COP Security IP (LAN) & Analog over Coax Transceiver Extender is a device to transmit IP & Analog over coaxial cable. This product enables you to replace analog cameras with IP cameras without installing new cabling. This product could simultaneously transmit analog CVBS video signal and digital IP video signal (or any IP or Ethernet LAN) over a single coaxial cable for distance transmission of 900ft ~ 1,500ft. It completely solves the problem of IP transmission delay by the hybrid transmission solution. This device should be used in pair, one as a local receiver and the other as a remote transmitter.
