Tech Trends: You Can’t Kill Coax

This legacy technology still serves a major role in both analog and IP video applications

PoC capability forms the basis for a number of other potential products, such as units at (or near) the head-end that service multiple remote transceivers, or remote PoE switches powered by the voltage on the coax. As Apple notes, “The typical coax-based IP product on the market today is either point-to-point, meaning there is one locally powered transceiver at the camera and one locally powered transceiver at the control room, or it is powered from a PoE port on a costly PoE switch. This is not efficient for multi-camera systems.”
