eBridge1PCR and eBridge1PCT are CAT5 to Coax cable Ethernet adapters that deliver data and power over the coax cable in a PoE compliant format. The paired set enables fast 10/100Base-T Ethernet digital communication to be transmitted over Coax cable. An eBridge1PCR receiver sends power over the coax to the eBridge1PCT transmitter under PoE protocol. The eBridge1PCT in turn delivers that PoE compliant power to a PoE enabled camera or IP device. eBridge1PCR will not deliver power to non-compliant devices, thus avoiding damage to improperly connected analog cameras. These plug and play units facilitate system upgrades from analog to IP cameras/devices utilizing existing legacy Coax and eliminating the costs and labor associated with installing new network cabling. In addition, data transmission and power over the Coax is possible up to 500m in comparison to 100m Ethernet maximum distance (see Maximum Length of Coax Type vs. Camera Power/PoE Class, pg. 3). A maximum range from headend to the PoE camera/device is 700m, taking into consideration that up to 100m of structured cable may be deployed at each end.
