IP CCTV

Circuit television system based on IP technology - a hybrid solution, in contrast to analog systems has more flexible structure that positively affects the overall security of the protected object.

The aim is protection of the object.

Objectives of CCTV:

  • identification of all persons that enter the territory;
  • track and control flows of people;
  • obtaining high-quality video and photo.

    • Requirements for identification:

  • to identify an unknown person object should be about 120% of the image size, and the image of a human head should occupy not less than 90 pixels;
  • for identification of known person object should be about 50% of image size, while height of the object should be at least 288 pixels;
  • for detecting intrusion object should be about 10% of image size, with the height of the object should occupy not less than 60 pixels;
  • for control a large number of people object should be about 5% of image size, and the height of the object should occupy not less than 30 pixels.

    • There are two types of IP video surveillance systems - a centralized and decentralized. The advantage of a centralized system is that the processing of all data from the cameras perform a central server - this allows less CPU intensive video cameras, but in case of refusal of a central server system is not operable. The advantage of a decentralized system is that the security camera is the ultimate network device that performs all the computations of current assets - it cannot operating additional hardware facilities (servers, workstations, etc.), which is economically feasible.

    The overall benefits of IP video surveillance systems to the analog:

  • scalability;
  • lower installation costs;
  • high reliability;
  • reduced cost of data storage;
  • better image quality.
    •
