REMOTE VIEWING OF ANALOG CAMERAS
This is due to their high reliability, and most importantly. relatively low cost of cable networks and equipment. True, when using a twisted pair, it is possible to provide a video signal transmission over several kilometers. no more.
Thus, the scope of this option. video surveillance of extended perimeters, significant production areas, etc.
Digital video surveillance systems, in comparison with analog ones, are more preferable in terms of organizing remote access. However, there are also pitfalls here.
REMOTE ACCESS AND IP VIDEO SURVEILLANCE
Since a digital signal can be restored without loss an unlimited number of times, theoretically there are no distances for an IP video surveillance system, but Honor follows the cost and features of organizing digital data transmission channels.
Wired communication lines require the installation of appropriate switches every 100 meters, supply voltage to them, the use of hermetic boxes (for outdoor use), which makes their use impractical for significant distances.

Fiber optic would be almost ideal, but its price and the cost of laying, coupled with the matching equipment, make its use economically feasible for trunk lines, but not for a single video surveillance system.
Radio channel. which use wireless WI-FI systems with the proper approach (using repeaters, directional antennas) can sometimes be an acceptable option.
REMOTE VIDEO SURVEILLANCE
To organize remote video surveillance, it is advisable to consider two options for building a system:
- A separate communication line is used for each CCTV camera (Fig. 1).
- Remote access is organized to the information processing device (video recorder, computer, etc.) (Fig. 2).
Obviously, if a channel provided by an Internet provider is used as a communication line, then we can talk about remote access via the Internet, which is discussed in a separate article.

However, there are cases when the technical possibility of such access for various reasons is absent or impractical. Then the laying of cable networks will have to be done independently, taking into account the following points:
REMOTE INTERNET ACCESS TO THE CAMERA
Remote viewing of CCTV cameras is carried out, as a rule, via the Internet. Both analog and IP video surveillance cameras are suitable for these purposes. Organization of remote access for network (IP) devices can be carried out in various variations:
- direct connection of the camera to the Internet;
- remote monitoring through a computer (PC);
- Internet access via a video recorder.
The first option is not available for analog CCTV cameras. Of the two remaining, the most widespread was access through a video recorder. Currently, almost all registrars support connection to the global network, and they can work with both static and dynamic IP addresses.
The easiest way is to view video cameras through cloud video surveillance services. A minimum of settings allows you to set up remote access with your own hands in a matter of minutes. This method works for any of the above options.
However, the “cloud” allows you to opt out of video recording systems on the client side. Thus, using special cameras, you can do without other equipment, viewing online video and archive directly.
REMOTE SURVEILLANCE SETUP
Since remote video surveillance via the Internet is most often used, the issues of setting it up for the user are the most relevant. In this case, access to the surveillance camera can be carried out in several ways:
- using cloud services;
- via a computer or video recorder;
- using mobile internet.
Setting up remote access through the cloud requires minimal effort. After connecting the video surveillance camera to the recorder or computer, the client part of the special program provided by the service is installed on the device from which the video monitoring will be carried out.
After that, the setting is carried out in accordance with the instructions attached to the software. It should be noted that this method of remote access is possible for both wired and mobile Internet.
If you already have a ready-made video monitoring system with a recorder, then you can see the material on how to set up video surveillance via the Internet. Please note that both wired and wireless connections can also be used here for remote access.
Recently, video surveillance through mobile devices is gaining popularity: phones, tablets, etc. At the same time, there are two options for organizing remote viewing:
- setting up access via WI-FI router;
- gaining access directly to the CCTV camera.
The second method is naturally much more mobile, but it requires the use of specialized cameras and appropriate software.
This method of working via the Internet is described in the article about P2P video surveillance. You may also find the article about connecting a CCTV camera, including via the Internet, useful.
