Abstract

An IP video surveillance system is able to combine IP video camera transmission, control functions for at least one IP camera and other network equipment, power over Ethernet (PoE) power for network equipment, diagnostics and analytic capabilities for system management and monitoring, with an existing coaxial cable infrastructure, twisted pair wire, or multi-channel twisted pair wire (category cable). The system interfaces to a network and further provides the capability to operate at distances well beyond network standards.
