IP (Internet Protocol) CCTV cameras connect to and communicate over an IP network in much the same way a PC will connect to the Internet. These cameras are able to record at a much higher resolution than analogue cameras, from 1MP pixels and above. They also can accommodate a wider angle lens to cover a larger area from a single camera. 4K Cameras that are able to record at 12MP and a full 360°.
There are limiting factors that affect IP cameras. Higher resolution cameras generate larger volumes of network traffic and data storage. These factors can dramatically limit the frame rate (number of images per second) the camera can generate. Processing time for the system to compress and transmit the data over the network can also result in a delay between the event and recording. This limitation predominantly affects the control of PTZ (pan, tilt, zoom) when controlled by human operators.
