Cabling and Wiring for CCTV Camera Installation
For most commercial CCTV systems, structured cabling running throughout the walls and connecting your security cameras to the server or NVR will be a vital component during surveillance camera installation. While more and more wireless security cameras are becoming popular, especially for home use, wired security cameras still reign supreme for more permanent and demanding security use.
IP Camera Installation Cabling
When using IP cameras – as most CCTV systems do these days – you will most likely be looking at Cat5E or Cat6 cables, which can transfer the large amount of data required by digital video and high resolutions at very fast speeds, and often over long distances. This is an upgrade from the coax cabling that usually powers analog security cameras; coax cables are reliable, but not compatible with IP camera installation. In many cases, Cat5e and Cat6 cables will also power the security cameras, eliminating the need for further wiring. This is called Power-Over-Ethernet and requires a PoE switch when the security cameras are not connected to an NVR. Wireless security cameras may need less wiring in the walls but will still require cables to power the security camera separately, usually via 110VAC power.
