Setting up a Chinese IP camera via a router. The best option for connecting an IP camera via a router to a computer. Single connection of IP cameras to surveillance via the Internet without the cloud

First, let's talk about the basic methods of transmitting a video signal.

Wireless method.

There are two main options here.

1. Connecting an IP camera via WiFi connection.

It does not matter whether the video camera has a built-in WiFi module or whether it is connected to WiFi router. It is recommended to launch the IP video camera for the first time with a direct connection to a PC from which you enter the wireless network login and password into the device’s software shell.

In addition, the IP address of the video camera is changed (in most cases, the default is 192.168.1.1). The IP address can be changed to a static “white” one, obtained for an additional fee from the provider, or you can assign a DDNS identifier to the device and access it in the future through a free DDNS service. After preliminary setup, it is turned off, installed in its normal place and started again.

Implemented WiFi connection cameras to the network - a new device appears, which you can connect to remotely, knowing your login and password.

2. Connecting a GSM or 3G camera.

In most cases we're talking about about devices with a built-in GSM module. Their setup is much easier, because SIM card already has its own unique address. But the client part of the software must be installed on the reading devices. In addition, when calculating operating costs, you should remember about the monthly fee for using the number and the Internet to the mobile operator.

Wired data transmission.

The classic way to transmit images from an IP video camera is via UPT cable of the fifth category (twisted pair). However, it has one significant drawback: the signal transmission range does not exceed 100 m. For longer distances, additional switches should be used.

There are hybrid devices that can work with both twisted pair and coaxial wire. They are capable of transmitting a signal at a speed of 100 Mbit/s. at a distance from 600 m to 1.5 km. For example, active amplifiers of the CooperLin series from the manufacturer ComNet.

LAN Power Systrms produces a series of devices VP-7000 (VIPER), which are capable of transmitting not only a video signal, but also power and control commands over twisted pair cable over a distance of up to 1.4 km. In addition, VIPER series amplifiers and converters are passive and do not require additional connection to the power supply network.

Devices that transmit digital signal from IP cameras via RG-59 or RG-6 coaxial cable.

Their popularity is due to the large number of analog networks that are now in use. For example, transmitters of the AVT-EOC950 or ST-VBT20 model are capable of transmitting images without loss of quality over a distance of up to 400 m via coaxial at speeds of up to 30 Mbit/s.

And a pair of devices model ST-VBT2/ST-VBR2 can increase the transmission range up to 2 km. For passive devices with the same operating principle, the transmission range is significantly shorter, it is 90 m at a signal transmission rate of up to 10 Mbit/s. For example, model B-204 from Channel Vision.

The most expensive method of transmitting video is optical fiber. However, this the only way transmit a signal without loss of quality over a distance of tens of kilometers.

To connect the fiber optic conductor to IP video surveillance cameras, you can use the Sigura ECO-plug video signal converter from Sigura B.V. it transmits images over a distance of up to 20 km.

POWER CONNECTION FOR IP CAMERAS

To connect power to IP CCTV cameras, two methods can be used:

1. Laying a separate power supply line from external source nutrition.

Depending on where the CCTV camera is located, indoors or outdoors, it may consume different amounts of electricity. To provide street cameras, a cable with the parameters of a standard household electrical network 220V 50 Hz is often used.

Inside the thermal casing, the adapter distributes the incoming energy to power:

• heating and air conditioning elements;
• infrared lighting sources;
• PTZ system power drives;
• the IP camera itself.

In this case, it is recommended to use a combined LAN cable ParLan combi U/UTP4 Cat5e. It represents a single cable, under the protective sheath of which there is a twisted pair in a separate foil protection and two power wires.

2. Power transmission of the IP video camera is carried out via twisted pair cable simultaneously with the video signal.

To do this, it is necessary that both the camera and the router support PoE technology. The only drawback of this technology is the limitation of the energy transmission range to 100 m. To solve this problem, several additional devices can be used:

PoE repeaters- passive devices that extend the Ethernet network segment by transmitting data and power according to the IEEE 802.3af PoE standard beyond the limited 100 m. Transmission can be carried out via UTP CAT5e/6 Ethernet cable. Additional gain range 100 m.

Several devices can be connected to a single circuit that do not require connection to the power supply line. In addition, the NIS-3200-102PR model has two rj 45 outputs, which allows you to power 2 devices at a remote monitoring site.

VDSL2 converters- can provide power transmission over a distance of up to 1.5 km. For example, the VDSL2 qBRIDGE-307m model is capable of providing power using PoE technology over a distance of up to 300 m for a standard UPT cable and over a distance of up to 1.7 km for a cable with a core cross-section of 0.5 mm.

PoE Extender- supporting devices this technology are capable of providing power to an IP surveillance camera, power supply to thermal casing elements, and operation of IR illumination at night at a distance of up to 500 m.

CONNECTING AN IP CAMERA VIA A ROUTER

When connecting one or more IP cameras to the router, you must sequentially perform the following steps:

1. The camera is connected to the computer.

2. Log in to the internal WEB interface of the IP camera. This can be done by entering the device's IP address in the address bar of any browser. The camera address can be indicated either on the packaging or in the device passport.

First you need to configure the PC subnet in accordance with the camera’s IP address by performing the following steps:

• Go to "Network Center" > "Connect via local network" > tab "Properties" > line "TCP/IP v4 protocol".
• Enter the static IP address of the PC so that the first two digits match the IP address of the camera.
• Launch any browser and enter the camera address in the address field.
We change the IP addresses of all cameras that will be present in the video surveillance system. We take the communicator address as an example, changing the last digit and writing it in the IP line of the camera.
• Save the settings, disconnect the camera from the PC and connect the device to the LAN port of the router.

3. Set up the communicator.

Different manufacturers make different settings menus, so you need to study them and find the "Port Forwarding" menu item. In the WAN menu item in the “Virtual server" tab in the list of virtual servers, enter the names and unique static IP addresses of the cameras.

If the communicator has a static IP address, then you can connect to the first video camera by typing http://(IP address): (port number) in the address bar. But most often the provider provides the user with a dynamic address. Therefore, you need to register with the DDNS server. We register as many unique names as there are IP cameras.

You also need to do port forwarding on the router. This is done as follows. We enter the WEB interface of the switch, find the tab “ Additional settings» WAN submenu. Go to the DDNS tab. Set the switch to “Enable DDNS Client”. And we indicate the address of the server from which we will receive services (where we registered). This could be a server from the router manufacturer or a third-party free resource.

We save the changed parameters. By going to the address registered in the DDNS service, we get access to the image of the camera that has been assigned this unique name (it is assigned in the “Virtual Server” tab).

The advantage of this connection method is the ability to remotely view video information from any device with Internet access, even without specialized software. The number of connected devices is limited not only by the number of ports, but also throughput the router itself and/or the channel width provided by the provider.

This limitation can be circumvented by artificially reducing the maximum resolution of the cameras and the number of frames per second to a level where the total information flow from all devices does not amount to approximately 80% of the switch's throughput.

CONNECTING THE IP CAMERA TO A COMPUTER

By connecting an IP video camera to a PC directly via a network card and entering its default IP address in the browser address bar, we will not receive an image or access to WEB interface. The fact is that both devices are in different address ranges.

It is necessary to first (temporarily) change the IP address of the computer in order to get into the internal program of the video camera (How to do this is described above).

Find an IP video camera using a regular browser or special program. For example, the Hikvision company has a SADP program, which is downloaded from the company’s official website. It is more convenient to work with the program if there are several IP video cameras from the same manufacturer on the network.

Cameras can also be connected via a switch. In this case, the maximum number of IP video cameras is limited only by the bandwidth of the cable going from the switch to the PC. Depending on whether the video camera is connected via a switch, directly or via a switch, the use of different cables is required:

Straight patch cord.

Serves to connect different types of MDI - MDIX devices: computer-switch; computer - router, etc.

Cross cord.

Designed for connecting devices of the same type (PC-PC, switch-switch)

CONNECTING THE IP CAMERA TO THE RECORDER

Unlike analog cameras, which immediately after connecting to the DVR begin to provide a picture, IP cameras require preliminary configuration. This is especially true for connecting to hybrid DVRs. The process of adjusting the parameters of IP cameras is carried out in several stages:

Connecting an IP video camera to a PC - directly or through a router.

Changing the IP address of the camera to one whose first 3 digits match the corresponding data of the DVR. The fourth number can be anything, including matching addresses that are already occupied by other equipment, since this network practically does not overlap with the office one.

The settings indicate not only the IP address of the camera, but also the data transfer protocol used. (must be similar to that used in the registrar). Most models require a login and password for authentication on the network.

Modern technologies offer many useful functions for users. One of them is the ability to connect to a video camera via the Internet and watch the recording anywhere in the world. You can access the video from any device that can connect to a Wi-Fi network.

Organizing video surveillance with the ability to view video remotely is not a difficult task, and it can be handled by a user who has a minimum set of knowledge in working with a PC and related equipment. To create such a network, certain equipment is required.

1. Digital video recorder. Its task is to receive recordings from cameras, process the signal if necessary (if the recording device is analog) and record it on a storage medium, for example, HDD. To access video via the Internet, the recorder must have a network interface. It can be software or server-based. In the first case, you will have to install special software on your PC, which usually comes complete with the recorder itself on disk. In order to view video from a recorder with a server interface, just go to the browser and go to a specific page. Many manufacturers of such equipment provide the user with the opportunity to download a browser extension from the website, which simplifies the task.
2. The local network. It is necessary to connect the camera, router and DVR. A local network can be organized wirelessly or via wires.
3. Router (router). It is used to create a local network if it is organized via Wi-Fi, and also connects the existing system with an external channel, that is, the Internet.
4. IP camera.
5. Software to watch the video camera from your tablet (smartphone).

Important! In addition to the equipment, you will need to obtain a static IP address. Typically providers provide it for a fee. The second way is to use cloud storage to watch videos.

Connecting one video camera

Obviously, the easiest way to create video surveillance via the Internet involves connecting one recording device. The procedure is simple.

1. The IP camera is connected to the PC, and its IP address is typed into the browser. You can find it out from the instructions; sometimes it is written on the device’s sticker label. This will be discussed in more detail below.
2. After entering the address in the browser, it opens network interface camera settings. You need to select automatic receipt IP addresses or manually register yours static IP address(you can find out on the Internet by searching “find out your IP address”). Here you should also enter a login and password to access the video remotely.
3. Next, you should specify the port through which the camera connects to the Internet. Typically it has a value of 80.
4. After specifying the desired address, the camera is disconnected from the PC and connected to the Internet.
5. Video viewing is available in the browser from any device. To do this, just enter the IP address in the search bar and specify the port separated by a colon.

Networking with a router

To create a system with multiple cameras, you will need to use a router: it creates its own subnet with access to all devices. The setup principle is similar to that described above. By analogy, you should go into the router settings and assign each camera its own port. Most often this can be done in the Routing menu. This item allows you to transfer external requests to different IP addresses of the system, that is, in the case of video surveillance to cameras.

So, the principle of operation will be as follows. Each device is allocated its own external port and its own IP address, which is already assigned by the manufacturer. For example, the external port of the first video camera has a value of 8080, and a specific IP is assigned to it. The second is port 8081 and its own IP. And so on for every camera on the network.

After setting up the router, you need to configure each camera. The setup is described above, but there is a slight difference: the IP address is not assigned to a common one (through which the user can connect to the entire system), but for each camera its own. After setup, you should connect each IP video camera to the router. You can see the recording by requesting “static IP address: external port of a specific camera” in your browser. Connecting the system with a DVR is completely similar. There are no differences in settings here.

Important! Many users correct setting systems cannot view video remotely. The problem is that they often try to connect to cameras from the same network in which the entire video surveillance system is registered. That is, a request is made from one IP address to connect to it. Obviously, this is not logical, and the device will not be able to connect to itself. You can only watch videos from other IP addresses.

For example, to connect the system to a tablet, you need to turn off Wi-Fi on it and turn on mobile network. The second option is that the tablet needs to be connected to another network that is not related to the organization of video surveillance.

Connecting the Wi-Fi camera

Connecting an IP camera Wi-Fi router in general, it is carried out according to the same scheme, but to watch the video you will need a special programs for viewing surveillance cameras via the Internet. Most often this is proprietary software from the camera manufacturer itself. The program is downloaded from the Internet and installed on a smartphone. Connecting the camera to the phone is done through this program.

Advice! It is much more convenient to use a Wi-Fi video camera where there is no possibility to run wires. It is quite logical to install such a camera in the entrance or at the dacha, and then connect to them from a tablet, smartphone or laptop.

How to find out the exact IP address of a video camera

An IP address is required to connect the camera to the Internet. You can find it out from the instructions on the device box, sometimes from a sticker located on the camera itself. Often this address is not entirely accurate, since it was registered for a family of video cameras ( model range), but not for specific device. In this case, you will need to use special software to determine the IP camera. One of the most simple ways To find out the IP of a video camera is to use the proprietary utility that comes with the camera.

If there is no disk, then you can download popular Angry IP Scanner app. With its help, you can find out the address of any device connected to a given local network. Another way - command line . In it you need to type the command “arp-a” or “ipconfig”. All connected devices will be displayed.

Advice! If you cannot determine which address belongs to the camera, you should perform this operation with the camera disconnected, and then with the connected one. The address that appears in the second case will belong to the camera.

Programs for viewing video surveillance from a smartphone or tablet

To watch video from a smartphone or tablet, you do not need to specifically configure the device. The method of viewing in a web browser was described above, but it is much more convenient to download a special application for these purposes. Currently, there are many utilities for the tasks described above, but the most popular are 3 applications.

1. TinyCam Monitor Pro supports up to 16 cameras simultaneously. Knows how to work with cameras from different brands. There are several multi-screens. Settings can be transferred from one device to another. You can directly write data to any media from the program. It is possible to digitally enlarge the image.
2. IP Cam Viewer allows you to work with several cameras at once, combine them into groups, and record video on media. There is an image scaling function. You can install the application widget for quick access and receiving up-to-date information. Supports about 700 models.
3. Exacq Mobile. Works on Android and iOS, supports 48 cameras simultaneously, easy navigation in the application, zoom function.

An interesting feature of these applications is that they can work with any IP cameras around the world. You can connect not only cameras installed at home, but also in other places. If the camera does not have a login and password, then simply enter its IP address in the application settings. Using such applications, you can connect to a video camera of an entrance, yard, or parking lot. You just need to ask those who installed the cameras about their IP address, login and password.

Video surveillance via cloud services

Cloud video surveillance technology is different in that the video is sent directly to network storage, and can be viewed from there. To operate, you need a recorder or camera that supports P2P technology. But a static IP address is not required. To configure the device, just go to its menu and check the “Cloud” or “P2P” box. Recording begins to take place in cloud storage.

There are paid and free services, which offer video storage space. One of them is shareware Ivideon: Connecting up to 15 cameras is free. All you need to do is complete a simple registration and you can use the services. In order to watch the video, you need to log into the site remotely and enter your login and password into the form on the site.

Important! The disadvantage of this method of organizing video surveillance is the speed limit, which can affect the bitrate of the video stream (the video may slow down).

Before you learn how to connect and configure an IP camera through a router, you need to take a closer look at the very concept of an IP camera, its purpose and areas of application. It is worth saying that you can connect the camera directly to a computer or laptop. But then you can limit yourself to a webcam (if you need one). Wireless IP cameras make sense if you have multiple video surveillance devices.

Every day IT technologies are moving forward, and it is no longer necessary to lay a lot of wires for all devices

IP cameras are used to organize a video surveillance system. They are used mainly in stores, shopping centers. Of course, they can be installed in your own home or on the street. They are usually installed during the renovation process (if it is a new room), since otherwise you will have to hide cords and wires under special structures. Many devices and appliances are switching to wireless connections. Here IP cameras are no exception.

Of course, such a system has its drawbacks. Surely everyone has a Wi-Fi router at home. This is the simplest example of using such a system. You just press the power button, and the entire house has access to the Internet. But you should also have noticed that the further away from the router the device through which you connected to it is, the lower the Internet speed. And in some places it is completely absent. It turns out that the powers of the router are not limitless. This is due to the quality of the received signal.

This means that the further your IP camera is from the Wi-Fi router, the worse the signal quality will be. In this regard, problems may arise with image transmission, audio stream speed, sound recording, and so on. Modern routers cannot distribute the network over long distances. Therefore, you should make sure that the camera is located close to the device that distributes the Internet. Then the thought arises that wireless connection cameras with a router and a computer will be relevant for small rooms. Otherwise, you will not be able to do without a wired connection.

So, if you have figured out the location of all devices, you can proceed to actually connecting and setting up the IP camera through the router. Take this moment seriously enough so that there are no problems in the future. It is worth noting that the use of Wi-Fi networks, for example, by other users, may add problems with signal transmission to the camera. You need to take this point into account. But with a wired connection such problems should not arise.

To begin, select the connection method: wired or wireless. For the first option you will need an additional UTP cable. It is needed to connect the camera to the router. If you have figured it out here too, move on to the next series of actions.

Setting up an IP camera

1. We connect the camera and computer with the appropriate wire.

1. Now you need to log into the camera control panel. To do this, you need to find the installed IP address of the camera and set the same subnet to your computer (usually the IP can be found on a sticker on the device itself or in the device box). For example, the address is 192.168.0.20. Launch the “Network and Sharing Center” menu in the control panel. There we find “Local Area Connection” and one of its tabs - “Properties”. We configure “Internet Protocol Version 4” according to the screenshot.

1. You have successfully configured the subnet. Next, launch the browser and enter the camera address http://192.168.0.20 in the field and enter the login information. They may also be on the box. If you still have one camera, then you don’t need to do anything else. If there are several, move on to the next steps.
2. We change the IP address depending on the local network range (you will need to know the router address). You will need to install the same one for the camera, but change the last digit. For example, the router has an address of 192.168.1.2, then the camera can be set to 192.168.1.11. To do this, you need to check the box next to the “Fixed IP” field and enter the appropriate data.

1. After saving the settings, you can disconnect the camera from the computer. We connect it to the LAN port of the router. Go to the local network connection settings (in the case of a wired connection between the router and PC). There we remove the previous settings (see point 2) and set automatic receipt of IP and DNS.
2. Having returned the patch cord to the network card, go to the browser at the new address of the camera, as in step 3. Find the Wireless menu to ensure wireless network to connect automatically. Here you will need the SSID and password. We save and restart the camera.

1. We disconnect it from the device and connect the others one by one. Their parameterization is the same, with only one caveat: they must have different IP addresses and ports. After finishing, you can proceed to setting up the router.

Setting up the router

1. Since all manufacturers have different settings menus, we will use the following example. We need a Port Forwarding menu item (or something similar). But first you need to enable virtual server, then enter the data according to the screenshot. Such manipulations need to be carried out for each camera (if there are several of them).

1. If you have a static IP address, simply write in your browser: http://your address:8181. This will take you to the page with the view from the first camera. But most often a dynamic address is set. In this case, proceed to step 3.
2. You need to enable the DNS client in the WAN menu. For example, Asus allows you to use their server for free. Otherwise, you can resort to using third-party services (NO-IP, etc.).

1. Having saved all the set parameters, you can, which you got after registering in the services. Ready!

Now you know how to connect and configure an IP camera via a router. From now on, you can install your own video surveillance system and even make it wireless. Enjoy!

Any user has recently had the information firmly stuck in his head that IP video cameras are much better than analog ones. This article will discuss the principle of connecting both IP and analog models.

After all, just a few years ago they appeared analog cameras high definition. These are AHD, CVI and TVI formats. In terms of resolution and picture quality, they are practically not inferior to the IP format, and the cost is several times cheaper.

As a rule, these are 1 or 2 Megapixel cameras. Their price segment is from 1000 to 2500 rubles. Moreover, if you already have an analog system installed and you just want to expand the number of cameras, or replace burned out ones, now it’s enough to buy modern inexpensive models with an OSD menu.

They have a switch on the shank that allows you to switch them to analog PAL mode.

Installation of video surveillance with analog cameras

Before you directly install video surveillance in your home, you need to draw on paper the locations of video points, cable laying locations, etc.

In order to maximize coverage of the entire space around the house, it is necessary to install at least one camera on each wall. It wouldn’t hurt to put another one on the roof in front of the front door.

Video surveillance materials

Here are all the materials you will need to install an analog video surveillance system:

• cable for powering the entire system from a 220V network

It is best to use the VVGnG-Ls 3*1.5mm2 brand.

• wires for switching in low-current switchboard - PUGV 1.5mm2

Do not confuse with KVK-V. The KVK-P brand is an outdoor option, and KVK-V is for installation inside the house. It is not UV protected.

• 3-core PVA wire cross-section 1.5mm2

First check that the number of video inputs on it is equal to or greater than the number of cameras.

• computer hard drive for video storage and recording

The minimum recommended volume is 1TB. Discs can be used as big size 3.5 inches and small 2.5 inches. Small drives are much quieter and generate less heat.

• power unit

For example, the same as used to connect LED strips. A standard power supply with a cable cross-section of 0.75 mm2 is enough for high-quality signal transmission over a distance of no more than 500 m.

Select the power of the unit according to the same principle as for LED strips. That is, the total power of all cameras + 30%.

They are needed to connect the cable to the camera itself and connect to the video input of the recorder.

If you don't want all your video surveillance to burn out in the first thunderstorm, don't skimp on this piece of protection.

It is most convenient to connect a DVR or UPS via a plug and socket. Please note that all these materials must be compatible with each other. Simple IP equipment will not work with analog equipment and vice versa.

You can choose ready-made video surveillance kits, or individual components - cameras, video recorders, cables, connectors, plus you can get acquainted with the current prices today.

220V power connection in the low current cabinet

The low-current switchboard, where the DVR, power supply, etc. are located, may be located in a different room from the general 220V switchboard, sometimes even in the garage or basement.
Therefore, the first thing you need to do is supply electricity there.

Ditch the walls and lay the VVGnG-Ls 3*1.5mm2 cable from the 220V switchboard to the low-current cabinet. You power it from a separate modular machine with rated current 10A.

In a low-current panel, connect the power cable to the terminals of another circuit breaker. It will be an introductory one for this cabinet. And directly from it you connect modular sockets and a surge arrester.

The arrester is connected according to the diagram below. The white and brown wire is the phase, the blue wire is the neutral wire, and the yellow-green wire is the ground wire.

Connecting sockets:

In the same cabinet there are:

• power unit

• DVR + 1TB disk

• UPS

The hard drive is mounted in the recorder itself. To do this, unscrew the screws and disassemble it. There should be a space inside for the hard drive.

Connect the connectors, and then screw the drive into place.

Please note that often the DVR case is also a cooling radiator for the disk.

Next, you power the UPS from the sockets through a regular plug. Most power supplies come without wires with a plug included, so here you will have to do it yourself. Use PVS wires and a regular Euro plug.

Mount a plug on one end of the wire, and strip the other and connect it to the unit at the 220V power terminals, designated L and N.

There is no particular difference in phasing or polarity where to connect zero and phase. Next, connect power to the video cameras.

If there are not enough 12V output terminals on the unit, it is best to use terminal blocks. Set them according to the number of cameras and label the pins as “+V” and “-V”.

Then, using PuGV wires, connect the 12V +V and -V output terminals from the power supply, with the corresponding connectors on the first terminal block.

It is better to use red wires for the positive wire, and black wires for the negative wire. The remaining terminals are powered by jumpers.

Installation and connection of cable KVK-P

Now you need to lay the KVK-P cable to each video camera, or rather to the place where you planned to place them. You can lay it indoors either in a plastic channel or simply on top of the walls.

On the street, if desired, it can be protected with corrugation, but not necessarily.

To protect the connection points between the cable from the recorder and the cable from the camera from snow and rain, mount a junction box on the wall and route the wires into it.

Next, remove the top layer of insulation from the cable, approximately 8-9 cm, and strip the two power cores. Press them with NShV tips.

Insert these wires into the male power connector. There are two connectors "+" and "-". As we already agreed before, the red wire will be the positive contact, the black wire will be the negative one.

After this, remove the insulation from the coaxial cable.

Carefully move the outer copper braid back so that not a single hair has accidental contact with the core in the center. Otherwise, the quality of the picture will be poor, or there will be no picture at all.

Expose the central core by 3-4mm and mount the BNC-F connector.

Insulate everything from above with a protective cap.

Connect the connectors together and close the lid tightly.

To prevent moisture from getting inside, it is necessary to use a box with sealed cable entries on the sides.

All other video cameras on the walls of your house are connected in the same way. To each of them you will have to pull a separate KVK-P cable.

Connecting wires on the DVR

Now all the video surveillance cables need to be disconnected in the low-current cabinet. First, connect the DVR itself via an uninterruptible power supply.

Then you strip the second ends of the KVK-P cable, brought into the cabinet, in the same way as shown above. In this case, connect the power wires (red and black) to the corresponding terminal blocks “+V” and “-V”.

And insert the end of the coaxial cable, with the BNC-F connector installed, into the free socket of the DVR. Where it says Video In.

Do the same with the remaining video cameras.

All you have to do is set up the video surveillance by connecting the monitor to the recorder via VGA or HDMI connectors.

If the low-current cabinet is located far from the computer, you can use a laptop to configure it. And after that, output the signal to the monitor using a separate cable.

To safely use the monitor for other purposes, you can connect a computer to the HDMI connector, and cameras to the VGA connector. Then by changing modes you can easily switch pictures from different sources.

All software To set up video surveillance, it must be included with the video cameras. If for some reason it is not there, then you can try universal software, for example from ivideon.

Connecting IP CCTV cameras with PoE

To mount and install IP cameras, in addition to the materials indicated at the beginning of the article, you will need slightly different components:

The PoE function allows you to transmit both signal and power over the same cable through one connector.

Attempts by users who have purchased a surveillance camera in a store that completely satisfies them in terms of price and capabilities to record and view a video stream often end unsuccessfully.

The reason is that the instructions offered by the manufacturer do not take into account the existing realities of setting up a home or office network segment.

However, keeping everything simple and making the connection correctly is relatively easy.

Features of IP cameras

If we do not consider the functional content of devices, all digital IP models can be divided into several large significant groups according to the data transmission algorithm and the level of remote access provided.

1. Products connected via USB port via cable. Such devices do not require configuration and are used in conjunction with those offered by the manufacturer or third-party software.
2. Devices that require data transfer via cable Ethernet networks. Such an IP camera can be connected directly to the network card of a computer or laptop, or to a router.
3. Models operating wirelessly. Such devices can act both as independent points with a unique access method, and as part of a certain infrastructure after integration with a router.

Depending on the wishes of the owner and the functionality provided by the camera, various schemes for accessing the video stream are configured.

The user can view the broadcast data using a smartphone, computer or laptop.

Algorithm of actions for connecting an IP camera to a computer

First, it’s worth considering the simplest reference case: a computer or laptop was not configured to work within a local network, and its default settings were not changed. In this case, making the correct connection to IP CCTV cameras is not difficult.

The algorithm of actions is as follows:

• The factory assigned IP address of the camera can be found out from the sticker on the device body or documentation;
• in settings network card the computer needs to specify an address that differs from the camera in the fourth set of numbers (separated by dots);
• as a gateway in the computer settings, the camera data is indicated in the first three groups of numbers, and one is indicated in the fourth.

After saving the changes, you can connect the port of the computer and laptop to the corresponding connector with a network cable digital device.

All settings are made according to the manufacturer's instructions, without any deviations in the writing of the address or in the access modes.

This method is convenient for users who access the Internet from a computer or laptop via a wireless access point.

In this case, you can connect and configure video in minutes to monitor and record, as well as quickly remove data from the device that writes the stream to a memory card.

However, this simple setup method will not work if you are using a router that forwards and assigns IP addresses to devices connected to it.

In this case, after performing the operations to directly connect to the surveillance device, the user will not be able to access the Internet without restoring the initial settings of the computer or laptop.

Setting up and changing an IP camera using the WEB interface

Almost all modern cameras allow you to configure settings after connecting using a regular web browser.

Service engineers or those who are constantly faced with the need for such an operation carry a netbook and a network cable with them.

This makes it possible to quickly negotiate settings to gain access to device settings.

The mechanics of how to connect a WiFi IP camera will allow you to do everything using your smartphone.

The following operations need to be performed:

1. look in the documentation or on the sticker on the case for the name of the access point (camera transmitter);
2. The username, default password, and IP address of the device are also located there;
3. a connection is made to the access point, a name and password are entered;
4. A web browser is launched on the smartphone, after which the IP is entered into the address bar to access the settings.

This option allows you to view the video stream even without changing any data.

However, to do this from anywhere in the world or from inside a network infrastructure isolated from the outside world, you will need to assign an IP address to the observation point.

This is done in several ways:

• in the case of an isolated network structure, the IP address of the camera must be in the used range of values. The easiest way is to contact system administrator and outline the task at hand. It will highlight one of the free addresses, which is entered into the device settings;
• for access from the Internet - it is most convenient to assign a dynamic name to the camera. To do this, a name service is specified in the settings; many of them are free. After assigning a unique identifier to the device, you can access it and receive a video stream from anywhere in the world.

Configuring an IP model connected by wire is done a little differently, which is why engineers prefer to do this using a separate laptop or netbook. The method for coordinating addressing is described above in the method of direct connection between a computer and a digital monitoring device.

Further user actions are identical to those described in the documentation for the device: entering the IP in the browser line, if necessary, entering a name and password, gaining access to the settings.

Setting up a router for remote viewing of cameras

Using a central router is the most common option for organizing a video surveillance network. In this case, cameras can be either wired or wireless.

In order to make the process of connecting several devices into a single network and further configuration simple and understandable, you need to do several preparatory operations:

1. find out in the router settings its IP address, which will be the gateway for the cameras (or access point for wireless models);
2. find out the type of addressing of connected devices (dynamic or static);
3. in accordance with the data received, carry out initial setup cameras, register IP. With dynamic addressing of the router (DHCP enabled), the option of obtaining an address automatically is set in the connected devices. With static, IPs that are different from each other are selected, differ from the router by the fourth digit and do not intersect with other devices connected to it.

After the work has been done, it is necessary to mount the cameras and, for wired ones, connect them with network cables.

A router with dynamic addressing of connected devices; for convenient orientation and stable mechanics of accessing cameras, binding should be done.

This is done in the corresponding settings section. It’s best to find out how exactly from the documentation of a specific router.

Logical mechanics of this action is quite clear: connected cameras are identified by MAC (physical identifiers) and they are assigned one of the free addresses from a certain range.

To ensure that cameras are always accessed using the same IP, you need to fix the resulting combinations in the settings after connecting the devices.

In this case, even after turning off and turning on the power of individual points, their addresses will not change.

In a router with static addressing and precisely registered IP of each camera, you don’t need to do anything.

You can immediately go to settings that allow you to conveniently access the video stream of each point.

To do this, you need to find a port forwarding block. This section of settings is found in every modern router.

Here it is written:

• port number;
• IP address of the camera to which it will be linked;
• if necessary, the port number through which the video stream is broadcast.

Most modern cameras do not require access to a clearly marked port. However, if the router does not allow you to omit it, such data is always provided in the documentation for the video surveillance device.

After setting up port forwarding, you can access any camera by typing “http://router IP: number of the port assigned to the device” in your browser.

Also, most recording and monitoring programs support this type of settings for receiving a video stream.

Conclusion

In conclusion, we need to mention those working with the manufacturer. Most of these devices are wireless.

To conveniently access the video stream, the user only needs to configure the camera in accordance with the manufacturer’s recommendations and register it in the cloud service.

After this, having access to the Internet, you can not only view broadcasts in real time, but also work with the archive and even (from some manufacturers) receive the functions of a software motion detector, video recording on a schedule, and sending alerts when a certain event occurs.
