Video surveillance as part of active protection system
A video surveillance system is an integral part of the overall security of any property: a construction site, a private sector or a production facility.
Everything is limited only by the correct choice of components of the system, as well as the correlation of their characteristics with the expected conditions. If there is absolutely no desire or time for independent selection, the store provides an opportunity to buy ready-made video surveillance kits for a very democratic price.
The standard system shall consist of:
1. Camera.
2. Registrar.
3. Wires.
4. Power supplies for each camera.
A more advanced system, for a small surcharge, will have:
• IR spotlights.
• Vandal protective jackets.
• Special attachments.
• Lightning rod, etc.
All of the above can be bought, while independently adjusting the search parameters in accordance with the available sum.
To choose from the client are analog, IP, HDTV cameras. During the purchase process, you only need to consider:
• Manufacturer (the site presents the four most popular);
• body type (PTZ, compact, dome, cylindrical);
• the number of TVLs (from 500 to 1000 TV);
• lens (fixed or varifocal).
As for the video recorder, here the store provides a choice. The range includes completely different models, both with and without a pre-installed drive. DVR DVRs can be bought with different number of connectors for cameras. If analog video surveillance is undesirable or cannot be installed due to the large scale of the territory, it is worth considering IP DVRs that can also be bought cheaply. Their installation and configuration takes much less time.
Why buy IR spotlights if the camera has a regular backlight?
Of course, almost 90% of models have built-in lighting, which works effectively up to 20 meters. But if the camera is at a height of 10 meters, it will be difficult to recognize the face of someone. Additional spotlights are installed together with the camera and have their own mount. Dimensions depend on the chosen model.
Power supplies
They are needed to connect power to the camera and, accordingly, twisted pair from the recorder. Blocks are made in protective buildings from moisture and precipitation. Some models have built-in batteries that ensure the operation of the cameras at the time of disconnection of the household or industrial network.
