Megapixel IP surveillance cameras have such advantages as high resolution, high speed imaging, digital presentation, signal processing and transmission. Ideally, it is better to use a separate network infrastructure for transmitting megapixel video surveillance traffic. This will avoid delays, minimize image quality losses, etc. But if the deployment of an isolated network is not included in the company's plans, and it is decided to use a common channel for video, then it is important to take into account a number of aspects. First of all, it is necessary to estimate the number of video sources and receivers in order to finally have an idea of the required bandwidth on each section of the network. In addition, you need to understand how fast each source will broadcast. It depends on the settings of the broadcasting equipment, video parameters and degree of compression. For optimal network configuration, you should know the volume of flows that will go through each part of the network. When choosing transmission technologies, it is better to place a bet on Multicast, although it is more complicated to install and uses its own protocols, it can significantly save, since the camcorder does not need to generate many video streams corresponding to the number of receivers: in this case there is only one stream. And this, in turn, saves computing power and does not load the network. This approach is extremely important if video surveillance serves for security purposes and, for example, anti-terrorism protection. The last moment of network preparation is the selection of appropriate equipment. It is important to pay attention not only to the price factor, but also to the characteristics that will achieve the desired effect. All cameras and infrastructure equipment must support this standard.
