IP camera connection. How to connect an IP camera to various equipment. How to connect an IP camera and a DVR directly to each other

Pictured is a 2MP wide-angle indoor IP dome camera with 2.1mm wide-angle lens, latest generation processor, H.264/H.264+/H.265/H.265+ codec support

What is required to connect?

Let's start as usual, from simple to complex. This time I propose to consider the nuances of the first steps of launching an IP video camera, namely, catering and connecting an IP camera to a computer.

We need to connect.

  1. The camcorder itself
  2. Power supply or PoE switch (optional)
  3. A piece of a two-core cable of the required length and section (for power supply)
  4. Power plug
  5. LAN cable 5th category (twisted pair UTP Cat 5e)
  6. RJ-45 connectors
  7. PoE splitter (optional)

As well as a small set of tools:

Crimper (crimper) for mounting RJ-45 connectors on a LAN cable (yes, I know, you can use a screwdriver, you can, but you don’t need =)), a screwdriver of the required size for mounting the power plug on a two-core cable and connecting it to a power source, a stripping knife wires, free time, and of course desire, where without it.

We will proceed from the fact that the video camera is already installed in the required place and we just need to connect it.

Connecting the IP camera cable

First of all, let's prepare the cables for connecting the IP camera to the computer. Let's start with power, since IP video cameras are quite demanding on power and have a fairly large current consumption, it is advisable not to save on the power cable. As an option, you can take a two-wire cord ShVVP with a cross section of 0.75 sq. mm - it is easy to install, as it is quite flexible. But I’ll warn you right away: the shell is afraid of sunlight, so it is not recommended to lay the cord outside the room without additional protection. A corrugated pipe can act as this, but only intended for outdoor installation, a LAN cable can also be packed into it. Next, we connect the IP camera via twisted pair.

Pinout poe cable for IP camera

We take a knife in our hands and strip the insulation from one side of the cord. Then, since this cord has an individual color for each wire, we clamp the brown conductor into the power plug terminal marked “+”, and the blue conductor into the terminal marked “-”. Consistent pinout of the cable for the IP camera will allow you not to make a mistake when connecting the power supply of the IP camera and will help to avoid the so-called "polarity reversal", which can be fatal for the video camera. Happened? Great!

While we put the cord aside and take care of the LAN cable, we strip the outer sheath of the UTP 5e cable on one side for a distance of 2 cm (more is possible, not critical) and arrange, having previously straightened each, the conductors in the following order from left to right:

  1. white-orange
  2. orange
  3. white-green
  4. blue
  5. white-blue
  6. green
  7. white-brown
  8. brown

Then we cut the conductors to a length of 1 cm and insert them, without changing the color sequence, into the RJ 45 connector, placing it with the contact group up.

After that, we crimp with a crimper, while leaving the second side of the cable as it is.

Next, we insert the power and LAN connectors into the corresponding sockets of the previously installed video camera and pull the wires to the place where the switch or DVR will be installed, or a personal computer, if it was decided to use it as a recording device. After connecting the IP camera cable, connect the power cable to the power source observing the polarity, this is important!

We crimp the RJ45 connector to the second side of the UTP cable according to the above method and connect it to the DVR, either to a personal computer directly, or using a switch if there are several cameras.

After checking the observance of the polarity and correct crimping of the UTP cable, you can turn on the power supply to the 220 V network.

With the installation work is over, we wipe the sweat from the forehead =) and proceed to the setting.

Connecting an IP camera to a computer directly or through a switch

Initially, we need to enter the addresses of the video camera and PC in the same subnet, and there are two options. Option one - the computer was previously installed, it is included in the existing local network and possibly has access to the Internet. And the second option - the computer did not previously have a connection to local network, and has just been installed. Let's start connecting the IP camera to the computer from the second option, since it is the simplest. Consider the setting on the example of an operating room Windows systems 7 (well, because it is at hand =)).

The computer is not connected to the network

A modern PC or laptop has a network card, which allows you to connect an IP camera to a computer directly through a switch. First of all, we connect the video camera to the LAN interface of the network card, or we connect the switch to the LAN, and the video cameras to the switch, if we use several of them.

After we have done this, the network connection icon should appear in the lower right corner of the screen.

We click on it right click mouse and select "Network and Sharing Center" public access»

In the window that appears, select "Change adapter settings".

Then, click on "Internet Protocol Version 4" and again, what to do, click "Properties".

And we see something like the following depressing picture, which hints to us that the address for this PC, in general, is not assigned and there is an option to get it automatically, which does not suit us a little, since there is actually nothing to issue it with. Let's correct this misunderstanding.

First of all, put a checkbox in front of "Use the following IP address"

and these fields become available to us for editing:

In which we, bearing in mind that the video camera has a default address of 192.168.1.10, that is, it is located in the first subnet (as indicated by the penultimate digit of the address), immediately enter the following values:

In the IP address line, enter the value 192.168.1.2 (well, because the 2nd address is free, in principle, the last number can be any unoccupied address within the 1st subnet) we get something like this:

The item "Main Gateway" remained, but in this moment we have no interest in it, for sim you can enter any address there, let's say 192.168.1.1 and at the output we will have this picture:

Click "OK" at the bottom of the window and consider that the network interface settings for this option are over.

The computer has a network connection and an IP address

But the first option is also possible, when the PC already has a connection to the local network and an assigned IP address, and then we need to do the following:

Exactly as described above, we get to the network adapter and right-click on the "Status" item.

Then, click the "details" button.

And we see the following: here we are interested in the values ​​​​highlighted by me, they will be different for you, but the essence of this does not change, we rewrite them, because the best memory is a pencil.

Then we exit this menu using the procedure described above (I will not repeat it), we get to this window that we have already seen.

In it, with a higher probability, it will either be the same as in the example, or some kind of address will appear.

If all the items in it are available for editing and addresses are already entered in them, then the connection of the ip camera of the video surveillance to the computer is completed and you can not read further. If everything is as in the example, then we proceed as follows: put the checkboxes opposite “Use the following IP address” and “Use the following DNS server addresses”, and enter the values ​​\u200b\u200bthat we saved on a piece of paper. As an alternative DNS servers you can specify four eights. Ready.

In the same window, click on the "additional" button and in the window that appears, click "add".

In the window that opens, enter a free address within the first subnet, for example, 192.168.1.3

The subnet mask will be written automatically, just click on this field, and then click the "Add" and "OK" buttons on all previous windows. Ready.

These actions were necessary in order for the PC to be able to work on two subnets simultaneously, which is necessary for further changing the IP address of the video camera and adding it to the software, which we will now deal with.

It's time to download and install the software. Despite the fact that it comes with the equipment on a CD, I recommend downloading it from the official website www.site.

Firstly, the CD is already an anachronism today and the CD drive is far from being present everywhere, and secondly, the version available on it is probably obsolete and why don't we get hold of a fresh version.

Configuring the software when connecting an IP video surveillance camera

Then, next to the "CMS" item, click "Details".

Perhaps someone will have a question, why exactly “CMS”, although there is an alternative in the form of “VMS”?

It's simple: This software was born first and why not give it the palm, and in general, it impresses me with the strictness of the lines and the austerity of the interface, and we will consider VMS sometime later.

So, despite the fact that there are more recent versions, we download the version from 03/07/16, because it is self-sufficient for Win 7 and does not require the installation of a plugin.

Then we start the installation.

Choose a directory to place the software (you can leave it by default)

In the future, all the time we press the “Next” button until we see this window:

in which we click "Finish", after which we receive an invitation to select the interface language of the installed software. Personally, I prefer Russian, but you are at your own discretion.

And, as expected, click OK. Done, the software is installed and moreover, it is running. We should see something like this

We leave everything in it as it is, the only thing you can do is put a kryzhik in front of "Autologin" so as not to receive this invitation in the future and click "Login". If a standard firewall is running on the PC, we get this warning

We allow access and see the following

Click "OK", in the lower right corner, select the menu item "System".

Adding IP devices, assigning an address

So, in the lower right corner, select the "System" menu item.

And then, just above "Devices".

We arbitrarily name it and click "OK" again.

Then we click on the created area and go to the menu item "Add device".

Where, in turn, we click "IP search" and we get approximately the following list of all video cameras and / or video recorders connected to this PC.

In your case, since we assume that everything is set up from scratch, there will be one or more devices with the address 192.168.1.10. If there is only one device, then left-click on it, after which the data should be rewritten to the lower area of ​​the window.

If there are several devices, and they have an identical network address, then we need to assign any free individual address to each device. To do this, select one of the devices and click "Edit".

After that, we assign an individual address, let's say 192.168.1.11 for the second device, 192.168.1.12 for the third, etc. Do not forget to click the "Change" button after changing the address and do this the required number of times, based on the total number of connected devices.

After that, we get a list of devices, each of which has a unique address. We just need to select one of the devices and click the "Add device" button, and do this for each new device.

Then click "OK" and consider that the adding procedure is over.

After that, an image from the selected device appears in this area. We do this for each added device.

We have considered the main points of connection. It seems to me that at this stage it makes sense to stop so as not to inflate the narrative format, we will consider further settings in the next cycles.

Development digital technologies allowed to bring to the market a huge number of network devices. Personal computers, tablets, game consoles and smartphones with powerful processors allow their owners to use all the resources of the Internet from almost anywhere in the world. IP cameras also belong to this category of devices. If you connect an IP camera to a computer with Internet access, you can use it to monitor the object anywhere in Russia, while all information will be written to the hard disk.

IP video camera in surveillance system

The network camera transmits data in digital format from using the networkethernet and IP protocol. organized on the principle of a local network.

It can use the following elements:

  • IP cameras
  • Routers
  • Registrars
  • Computers
  • Power supplies
  • Executive devices

The camera digitizes the image, processes and compresses it according to a certain algorithm. Then, through the WEB interface, via a twisted pair cable or Wi-Fi, the video stream is transmitted to the Internet. When organizing wireless video surveillance, the router works as an access point. The network may have a video recorder that itself finds all connectedIPcameras, and records information. To manage and configure the system used computer with installed software.

In the absence of a video recorder, video files are recorded on the hard drive of the computer.

Since the design of digital IP cameras includes powerful processor , then it is better to carry out their power supply from mains power supply and not from the battery. This is due to the rather high energy consumption. Most modern camera models support the PoE (Power over Ethernet) function. This allows you to supply a constant voltage supply to the cameras over the same "twisted pair" through which the video stream is broadcast.

In this case, the cameras are powered by a DVR that must support this function.

Reception point video information from an IP camera does not depend on its location in the network. Any user, and password, can access the network with personal device and receive audio and video information. Camera modes are configured using special drivers. With their help, the modes of camera activation, recording and viewing are selected. Advanced software allows not only to select operating modes, but also to use an intelligent situation analysis system. This allows you to use IP video surveillance as a powerful set of facility security tools.

Camera connection principle

Connecting an IP camera to a computer is easy. Some difficulties may arise setting it up. The connection is carried out using a special cable equipped at the ends. connectorsRJ-45 . One connector should be inserted into the corresponding socket on the camera body, and the other should be connected to the computer.

Since most users use wired Internet, the Ethernet jack on the back of the computer is occupied network connection, so you need to use a router to connect the IP camera.

The router has a WAN connector and several LAN connectors on the back wall. It is necessary to connect a wired Internet line from the provider to the WAN connector, and the LAN ports are used to connect any network devices, including IP cameras. Some models of routers and camcorders support PoE function, that is, the camcorder will be powered by the same cable that used for video streaming. If this is not provided, then a separate adapter must be used to power the camera.

Camera connection viaWi— firouterimplies a certain sequence of actions:

  • Connect the power adapter to the camera
  • Install Antenna
  • Connect an Ethernet cable to the router
Each network device has its own IP address.

If the camera is new, then the address is usually in the instructions for the device and on the software disk. It is also written on the packaging. If the camera was purchased from the hands, then this information may not be available. In this case, you need to find the manufacturer's website where you can find this information.

IP camera setup

Regardless of the camera connection type need to customize. To do this, it must be connected to a computer. network "LAN» cable and enter the address. After the address is typed into the browser, you can enter the network interface. In the line "IP address" you need to write the address, provided by the provider or check the "Receive automatically" box. Next, the port that is used by the camera is determined.

The default is port 80.

After that, you need to register a username and password for enter the camera interface. After that, the camera can be disconnected from the computer, and connect the cable from the Internet provider to it. To view the image from any device, you need to type the address and port of the camera.

If you plan to connect several IP cameras, you will need a router. It organizes a local subnet, which will include all cameras.

When creating a subnet, the network address of the router and the addresses of all network devices are used. Each camera is assigned its own address and port.

Usually, a software disk is supplied with an IP camera, which also contains all the necessary drivers.

Video surveillance using a registrar

To organize remote video surveillance, IP cameras can be connected to a DVR. Such a monitoring system very reliable in operation Moreover, there is no need for a separate power supply for cameras, since most DVRs support the PoE function, and power will be supplied to the cameras through data cable.

The disadvantages of such a system include a strictly limited number of cameras that can be connected to the registrar, and in case of building up the system, the device will have to be replaced.

And its HDVR hybrid modification are full-fledged network devices, and are equipped with a LAN port that allows you to work via the Internet. If NVRvideo recorder designed to work only with IP cameras, the HDVR recorder allows you to connect both digital and analog cameras. DVR connects to the network through a router like any other network device. The registrar receives all settings through the built-in DHCP server.

Video surveillance kit usingIP models may consist of the following elements:

  • Indoor and outdoor cameras
  • router
  • NVR
  • Cable set
  • Network adapters
  • HDD

If devices support the PoE function, then the need for network adapters disappears. Typically, a hard drive is not included with the recorder and must be purchased separately.

Features of IP cameras

Thanks to the introduction of innovative developments, they are moving to a leading position in video surveillance systems. Despite the high cost, IP models are installed in especially responsible security systems. High-definition analog cameras provide very high quality images, but some features of digital cameras are simply not available to them.

In modernIP devices, the following technical solutions can be used:

  • 3D DNR
  • D-WDR
  • IR filter

During the operation of surveillance cameras, for a number of reasons, distortions called “snow” may appear on the image. They may be of an electromagnetic nature, associated with external influences, or caused by the inherent noise of the electronic components of the camcorder.

3D DNR technology allows you to analyze the image using the built-in program and completely remove noise from the image.

D-WDR is an extension function dynamic range signal. During digital processing, both very dark and very light areas of the image are equally clearly depicted on the image. PoE technology provides a constant voltage supply to the camera via the information line, without the use of additional wires.

When working in low light conditions, the camcorders operate using infrared illumination. A special filter allows you to remove this component, as it degrades the image quality.

Smart functions of camcorders

Intelligent functions have been introduced into modern digital camerasSmart

  • Antifog
  • Autotracking
  • Face recognition
  • Selection of the area of ​​interest
  • Fixing car numbers
  • Sound change control

In conditions of poor visibility due to fog or smoke, you can clean up the image by automatically adjusting the contrast and white tone compensation. Automatic tracking allows you to capture moving objects, control and analyze their trajectory, and record objects left unattended.

Face recognition technology is widely used in video analysis and is used to automatically count people in the viewing area, and control the behavior of suspicious persons, moreover, they are detected by the program without operator intervention.

The selection of the area of ​​interest allows you to change the image quality and increase the detail in a limited area within the frame. Some IP cameras may highlight up to 4 areas due to quality degradation in other areas.

The camcorder can be programmed to registration of car numbers, and all information processing is carried out by means of the camera itself. Since all IP cameras are equipped with a microphone, an alarm can be provided if the sound level goes above or below a given threshold.

Conclusion

According to experts, IP video cameras make sense install on important sites. Despite the high cost, such cameras have more capabilities than analog devices. In some cases, when using hybrid DVRs, it is possible to combine both types of cameras in one surveillance system. This will reduce the cost of organizing the system and, at the same time, save high level object security.

Today, the use of IP cameras is popular. They are installed in public facilities, mainly to capture various images. Each device has an internal web server, and it can fully function with Internet networks using a connection via WiFi connection either WAN or LAN networks. Each device has its own IP address, which can display video images on the screen of any personal computer who has internet access. To view video images, it is not necessary to install special software, a browser is enough.

In addition to the standard image transmission, some devices have additional functions:

  • sound reproduction;
  • ability to transfer voice messages through the built-in speaker;
  • installed motion sensors, night vision, etc.;
  • Possibility of e-mail notification.

Cameras are used not only for the safety of surrounding citizens, they are also installed at various work sites, such as mines. It happens that video surveillance serves for cultural acquaintance of people with the territory.

Since most people switched to video surveillance, the question arose of how to connect an IP camera to a computer directly. Of course, users who are not well versed in computers will not be able to immediately connect a video camera, but those who communicate with the computer on “you” will certainly be able to do this.

Video camera installation

An IP camera is connected directly to a computer through a connection. This method connections of an IP camera powered by twisted pair are familiar to everyone, because they connect WiFi routers, as well as a direct wired Internet connection, set-top boxes and many other different hardware. If two or more video surveillance devices need to be connected to the computer, then the IP camera is powered over twisted pair in the same way only with the help of a router.

Each device has its own IP address, which you must know to connect to a personal computer. Eat special programs, which help to determine the IP address of each device individually. Also, usually complete with a video camera should go installation disk, which contains device drivers and special programs.

Once you know the IP address, you should change it using standard or downloaded programs, since your local address must match the local network address. It is possible to change the IP address via the local network. To do this, go to its properties and select the Internet Protocol. In the window " IP address» enter the updated address, and in the window « Main gate» Enter the address of the video camera.

After that, access to the device can be obtained by entering its address in the browser. When you go to the IP address of the device, you can immediately connect to it and see the image. So in a simple way used by everyone who wants to see their own webcam from the monitor screen. In addition to the fact that you can record from an IP camera to a computer, it is possible to provide a connection for an IP video surveillance camera to a DVR.

The process of connecting a camera that has a Wi-Fi interface

To accomplish this task, you must perform the following steps:


After all the steps taken, the video link should work and be displayed in the browser of a personal computer.

To connect multiple cameras, you need to have router. The router has its own input for connecting to the Internet and many inputs for connecting IP cameras. It is configured in exactly the same way, the only difference is that instead of one address, a set is written, since each device has its own unique address, and it must be registered to access the device. Each camera has a unique port number, and the fourth digits must be different.

How to connect an IP video surveillance camera without a computer

It is also possible to use the connection without a PC. For this use special registrar And storage disk data that contains the recording from the IP camera. All this is connected to the monitor directly and displayed on the screen.

This method is used only if HDD, recorder and cameras were purchased from the same manufacturer. This is feasible because different manufacturers may not be compatible with each other and therefore can give you a lot of problems when connecting. And not the fact that the connection will have a successful result.

Video surveillance over the Internet

At the moment it is possible to view your camcorders using cloud. This will get rid of a lot of complex settings, port assignment in the router and DNNS settings. cloud services are easier to use, and it is also possible to purchase a video camera from them, which will already be with ready-made settings. And all that remains to be done is to create a connection to the router and download software application to your mobile device. Thanks to this, you can configure in a matter of minutes without using a personal computer. As well as nice bonuses, for example, on cloud service Videon it is possible to connect several cameras for free, because you will start paying only when the number of cameras exceeds 15 pieces.

Providing power for the IP camera is the key to uninterrupted and successful operation. For this, IP camera technology is used. . The PoE IP camera can be directly connected to the power supply and provide uninterrupted monitoring of the object. Power supply for IP cameras provides power, sometimes used for connection splitter to connect the camera via PoE injector for IP cameras. An injector is needed in order to connect a camera with an IP address to the unit if it does not have a PoE connection. In this case, the injector plays the role of a conductor. There are cameras with built-in PoE that do not need to be connected to an injector. Multi-channel injector uses the connection of all cameras to it and provides them uninterrupted power supply due to the fact that a PoE power supply for IP cameras is connected to it.

Today in the video surveillance industry there is a trend of a gradual transition from analog cameras to modern digital IP video capture devices. This fact is quite natural, since analog devices have not kept pace with the development at all. modern technologies when both offer the user much best quality images and ease of use of the video surveillance system as a whole for virtually the same amount. Plus, with the help of the latter, it is quite easy to organize remote control of an object, which in our time is also becoming an important point when creating a video surveillance system.

In connection with the widespread transition to IP cameras, more and more people began to be interested in the question of their correct connection and setting. Of course, for a novice user, this may seem like a difficult and insoluble task, but for those who have been familiar with a computer for a long time, connecting and configuring IP cameras will not cause much difficulty. In this article, we tried to describe in as much detail as possible the process of connecting a digital IP camera to a computer, as well as tasks correct settings For correct operation devices.

Connecting an IP camera to a computer

Any IP camera connects to network board computer directly via . If there are several cameras, then to access the image viewing from each of them, you need to connect IP cameras through a router.

All IP cameras have their own address by default, and before we start configuring the IP camera, we need to know it. To do this, you can use specialized software, which usually comes with devices, or download the necessary utility on the manufacturer's website. In addition, the IP address of the camera is usually written in the user manual or on the attached label of the device.

If you try to enter the camera interface through a browser on the first connection, you will surely fail. This happens because the computer and the camera are configured to work on different subnets. After we know the IP address of the camera, you need to bring it in line with the one used in your local network.

Today, the creation of remote video surveillance is especially important. Surveillance via the Internet is quite easy to implement using a router with a dedicated IP address. Online video surveillance can be implemented in 4 ways, which you can read about.

Creating remote video surveillance is becoming more and more accessible with the help of special ones. Moreover, when implementing cloud video surveillance, you do not need a dedicated IP address, and equipment settings are reduced to a minimum.

For video surveillance at remote sites, you may need GSM cameras. They will be convenient to use in a country house, garage, or country house, as they can promptly warn you about the occurrence of various extraordinary events at the facility by sending a message to your mobile phone. You can read about GSM cameras for video surveillance at the link.

To find out the IP of the local network, you need to go to the "Sharing and Network Control Center", then in the "Connections" line, select the item "Ethernet" or "Via LAN". In the window that opens, click on the "Details" button, then a new tab opens for us, on which we find out the IP address of the local network - we look at the line "IPv4 default gateway", in our case the computer is on the network 192.168.99.*. Let's say the IP address of your camera was like this: 192.168.0.24, now our task is to replace it with 192.168.99.24 - you can have any other numbers, but the principle remains the same.

Find out the IP address of the local network

You can change the IP address of the camera using the same program through which you recognized it. At Hikvision, for example, it is called SADP, other cameras come with their own programs. After the IP address of the camera is adjusted to the address of the local network, the image from it will become available at the new IP address, in our case it is http://192.168.99.24.

Changing the IP address of the camera through its web interface

There is another way to get into the web interface of the camera, which involves changing the IP address of the local network. For example, the IP address of our camera is 192.168.0.24, and the computer's local network is 192.168.99.22, and we need the computer and the camera to work on the same subnet (.99. or.0.). To do this, let's bring the subnet of the local network in accordance with the address of the camera, for example, change it to 192.168.0.22. To do this, go to the "Sharing and Network Control Center", then in the "Connections" line, select the item "Ethernet" or "Via LAN". A window should appear, as in the screenshot below. In this window, click on the “Properties” button, then select “IP Protocol version 4 IPv4”, call its properties, and manually enter the IP address 192.168.0.22, and specify the address of our IP camera 192.168.0.24 as the gateway. Don't forget to save your settings.

Specifying an IP address to access the camera. The picture is available for enlargement

Now, through any browser, we go to the web interface of the device - we drive in the camera address 192.168.0.24 in the search bar. If you did everything correctly, a window should open for entering the username and password, which we take from the instructions for the camera. They usually default to admin/admin, admin/12345, admin/00000000, and other easy combinations. After entering the data, you will be able to view the image from the camera, as well as camera settings.

In the web interface of the camera, you need to match the IP address of the camera to the address of the local network. Usually these settings are on the tab called "Network". For example, your router is located at the local network address 192.168.99.22, which means that for the camera we need to set an IP like this: 192.168.99.24. We put a tick in the IP settings on "Fixed IP address" - we will need it to configure it, and write down the data:

  • IP address: 192.168.99.24;
  • Subnet mask: standard 255.255.255.0;
  • Gateway (IP address where our router is located): 192.168.99.22;
  • DNS IP Address: 192.168.99.22.

If you do not want to view your cameras via the Internet, then simply check the box next to Dynamic IP (DCHP).

Now you need to assign a port to your camera. By default, port "80" is open, so if your camera does not have such settings, you must use it. If this line is available, we prescribe the values ​​​​manually for each camera. For the first, for example, we will set port 8081.

Scheme of connecting IP cameras to a computer through a router and creating access via the Internet

Save settings, disconnect network cable camera from the computer and insert it into a free port on the router. After that everything manual settings We reset the IP addresses that we generated earlier in the local network to connect to the web interface of the camera to automatic - just set the dots to receive the IP address and DNS addresses automatically, and connect the router to network card computer. If necessary, we enter the web interface of the camera through the router at the IP address assigned to it ( http://192.168.99.24), and set wireless connection via Wi-Fi. We do the same settings for each camera, and do not forget to assign different IP addresses and ports to all other devices, if this is allowed (on some cameras there is no manual setting of ports, for them it will be standard - "80"). For example, assign IP 192.168.99.25 to the second camera, and port 8082, third camera 192.168.99.26/8083, fourth camera 192.168.99.27/8084 and so on.

For video surveillance using IP cameras through a computer, you may need special programs. They can be bundled with the equipment or downloaded separately from the Internet. You can read about them at.

Instead of IP cameras, in some cases it is more expedient to use. For example, when the video surveillance system consists of only one camera.

You can organize video surveillance in your country house using a regular 3G router and several IP cameras. At the same time, it is very important that there are no signal interruptions in your area. cellular network. Read the article on how to implement country video surveillance in this way.

Setting up a router to view IP cameras via the Internet

After configuring the cameras, it's the turn of the router:

  1. We connect all configured cameras to the router via network LAN ports, or via Wi-Fi;
  2. We connect the router to the computer via Wi-Fi or a network cable;
  3. We go into its web interface, and proceed to port forwarding, so that the router, when accessing a certain address from the outside, knows which camera to issue from the internal network.

These settings can be found in sections called "Port Forwarding", "Routing", "WAN", in the "Virtual Server" or "Virtual Server" tab. First you need to check the box to activate the virtual server. Depending on the model of the router, you can stumble upon similar settings:

  • Service name - we prescribe manually, for example, "First camera";
  • Port range - the port that we assigned in the settings of the first camera (8081);
  • Local IP address (camera IP address) - for example, we have it 192.168.99.24;
  • The local port is 8081, or 80 if the camera has no port settings;
  • Protocol: TCP – IP camera works with this protocol;
  • Protocol number: leave the field empty, or write any number, for example, 1.

Connecting and configuring an IP camera through a router

We prescribe the settings for each camera according to the above described principle. Do not forget that each camera must have its own different IP address and port, if, of course, there is such an opportunity.

In order to be able to connect to the cameras from any device with Internet access, you will need a static IP address. You can order it from the provider for a fee, or use the DynDNS service. Using this service, you can assign any domain name to your dynamic IP address, such as http://your_unique_domain.ddns.en. But first you need to activate this function in the router settings. In some routers, these settings are located in the "WAN" section on the "DDNS" tab. There you can specify the server (DynDNS, ASUS, NO-IP, etc.), your 3rd level domain name, and other necessary settings. Next, we register a domain name on the service (by the way, ASUS routers have their own free service for these needs), and prescribe it in the settings of the router.

Checking the functionality after configuring IP cameras

After configuring the IP cameras and the router, we will check their performance. To do this, open a browser and address bar write the IP address of the camera and its port in a similar way: http://your_unique_domain.ddns.ru:8081, or http://your_static_IP_address:8081. When accessing the camera from your computer located on the same local network as the cameras with a router, simply enter its unique IP address into the address bar.

If you configured everything correctly, the system should work, and when you write different ports in the address bar of the browser, you will see a picture from the corresponding camera.

So, we have sorted out the question of how to connect an IP camera to a computer and configure it to work on a local network, as well as organize access to it via the Internet from any device. Remember that some nuances on the equipment different manufacturers may vary, but the basic principle of tuning will always be the same.

    Hello, thanks for reading the article.
    the question is, any, roughly speaking, not expensive ip-camera, can I connect to the laptop by “conjuring” with the ip-address?

    ps I need to shoot a video in the dark with an IR camera. For these purposes, it will be enough for me: camera-ip, software, laptop?
    Thank you

    1. Hello, of course, you can connect any even the cheapest IP camera to your laptop. Everything you described will be enough to connect one IP camera to a laptop.

      Are there ip cameras with wifi and the ability to connect directly to it without using a wifi router?
      Those. there is a phone with android and wifi, there is an ip-camera with wifi in an open field 😉 how to make them friends?

      1. Try using tinyCam Monitor to connect CCTV cameras to Android. With it, you can connect most IP cameras that have a WiFi access point to your Android gadget.
