Linovision EOC-Converter is a combination of Power over Coax (PoC) and Ethernet over Coax (EOC) converter. With proprietary ePOE technology, it is designed to transmit both PoE power and ethernet data over coaxial cables or twisted pair cables, including siamese cable, CATV cable, power cable, Cat5E/Cat6, etc. The max transmission distance can be 3,300ft. It is super useful to upgrade the analog camera system to an IP surveillance system without replacing legacy coaxial cables. It can also be used in elevators to get power and network from coax or twisted pair cables.
