With a transition from analog to digital video continuing, there remains a crucial requirement for reliable transmission of the video signal during today's period of coexistence. With many legacy installations it has been coaxial cable handling images from a camera to monitoring, recording or both. Coaxial has its limitations, including restricted transmission distance, signal degradation over long cable runs and interference.

Networking, digital and Internet Protocol (IP) have ushered in unshielded twisted-pair (UTP) cable and high-speed Ethernet, employing IP to carry the digitized video images. In some installations wireless transmission–radio-frequency, microwave, WiFi and mesh nets–play a role. Most enterprise security video designs are not totally wireless. Instead, the technology is applied to meet certain geographic or operational challenges
