  • requires minimal time for installation and configuration of the entire system, provided that the cameras are not many;
  • can use wifi ip-camera, thereby stretching the wires to the point of installation - One of the options for wireless video surveillance;
  • IP-camera plugs into a standard wall outlet for the Internet.
  • Minus:

  • video archive is not the standard means of the camera itself;
  • limitation of functional capacity
  • the camera itself;
  • when using a large number of cameras on a single object seriously increase the network bandwidth requirements for the Internet channel and the requirements imposed on the configuration of a router or need to buy a lot of ip-addresses from your provider;
  • for the implementation of video archives, operation, or on motion detection, alarm, you need a computer with the proper software, which should always be included, and it all leads to a substantial increase in the cost and reliability of the entire system.
  • 3. Also, video surveillance can be done not only through the Internet, but also in one or more of the combined local area networks. This implies the following.

For greater clarity, consider an example. When a high-rise office building on each floor of the guard sits and stares at the image with the camera through the monitor which is connected directly to the DVR. In turn, video recorders on all floors connected to the LAN of the building and also to the local network and computers are connected in common Security Center of the object. And center operators are surveillance over a local network. Using a local network, rather than the public network - the Internet, you greatly increase your safety as Third party to remotely connect to the system is not possible. Also note that the video surveillance for your home or apartment is much more suitable for the first option.

    4. Combined video surveillance - when using all three options in the first one. Very often there is video surveillance in schools combined. As part of the video is done specifically for parents, the other part for security systems and some to pass certification exams.
