They can store video either with: on board memory, send to an FTP Server, be controlled by an NVR (Network Video Recorder) Resolution is measured in standard pixels Features may require that you pay additional money to unlock capabilities Networking A single 5 MegaPixel Camera can use up 30Mbps of Bandwidth. Multiple Mega Pixel cameras can bog down a LAN. “Pushing Intelligence to the Edge” means that decisions about when to record video and other features are made by the camera itself and not a central NVR. Parallel Networks are used to give surveillance equipment their own dedicated Ethernet Network so that it does not interfere with Computer and VoIP communications. Power Over Ethernet allows you to power your IP Cameras through the network cable. Virtual PTZ Virtual PTZ allows you to zoom in on a specific area of a video …
