Installation of video surveillance

If you want to install a video surveillance system in your home or office, one of the main decisions to be taken is to choose  the type of video camera - network or analog.

Deciding on the use of IP cameras is not always easy, because there are advantages and disadvantages to each type of camera.

The main difference between the two types of cameras is the way the video signal is transmitted. Analog video cameras convert a video signal into a format that can be obtained by a television or other receiver, such as a video recorder or a security video monitor.

Network video cameras, also known as IP cameras, compress the video signal using a dedicated video compression module, after which the signal is transmitted over the network using the built-in HTTP server of the network camera.

This allows the IP camera to function as a network device, which makes it possible to view the received video image not only through an existing local network, but also through a web browser that can connect via the Internet.

To compress the video signal, as a rule, algorithms of frame-by-frame or stream compression are used. In the first case, each individual frame in the video stream is compressed separately (for example, using JPEG compression in the Motion JPEG algorithm). In case of streaming compression, in addition to individual compressed frames, only the difference between frames (MPEG4, MPEG2) is transmitted for other frames.
Both types of video cameras can transmit signals, either over a wireless channel or using cable connections, such as a twisted pair of the fifth category.

IP cameras have the added advantage that they can use switches (switches) and routers, which will expand the network built on a twisted pair to a wider scale.
