IP(network) Security Camera Systems basically capture video and audio data and sends it through network equipments to network video recorders or routers. The NVR functions as a recording unit, as well as transmits video streams from the cameras over the LAN and internet for local and remote viewing. An IP camera requires a high speed internet connection (such as DSL), network switches or router. Another advantage of IP systems helps in eliminating excess cabling. The camera cables need not have to go to the NVR directly, it can be connected to a network switch located close to couple of cameras and just one Ethernet cable can run up to the NVR, saving in cable and labour costs.
The functions are similar to the HDCVI or HDTVI, but with the IP systems you can have cameras with much higher resolution ranging from 1 megapixel to 12 megapixels. This helps in clear detection in more bigger areas. However a strong network backbone is needed for handling high bandwidths of these network systems.
