In all but a few cases where a user's network has been designed specifically to include CCTV, a separate CCTV network is generally installed as part of a new IP CCTV system. The high volume of digital data traffic between cameras and recorders would severely slow down or even crash the average commercial or retail network.

Depending on distance from CCTV network switches and recorders most IP cameras are powered by power over Ethernet (POE) and do not require a local power supply at each camera. The camera power is carried from the network switch or recorder on the same Cat5 data cable as the system uses to send the image data in the opposite direction from camera to recorder.

Most people automatically associate IP CCTV with High Definition (HD) quality but not all IP cameras and recorders provide High Definition HD quality images. If you choose an IP CCTV system to achieve HD quality images you need to ensure that the system provider is aware that you require full live and recorded HD image quality from your system.

Upgrading a traditionally cabled (co-axial) analogue CCTV system to achieve HD quality images may not require the expense of replacing existing co-axial cabling with new (Cat5) network cable. The latest technological advances allow us to fit HD quality cameras and recorders on to existing co-axial cabling and local camera power supplies (depending on quality and length of existing cabling).
