Altronix eBridge400PCRM and eBridge100TMeBridge100ST are CAT5e to Coax cable Ethernet adaptersMedia converters that deliver data and power over the coax cable in a PoE compliant format. The paired set enables fast 100Base-T Full Duplex Ethernet digital communication to be transmitted over Coax cable. The eBridge400PCRM receivers are powered by any UL Listed, PoE midspan or endspans and pass power over the coax to the eBridge100TMeBridge100ST hardened transceivers. This enables the eBridge400PCRM to be used in a managed manner, allowing for remote camera reset. The eBridge100TMeBridge100ST, in turn, passes PoE compliant power to a PoE enabled camera or IP device. These plug and play units facilitate system upgrades from analog to IP camerasdevices 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 300m in comparison to 100m Ethernet maximum distance (see Maximum Length of Coax Type vs. Camera PowerPoE Class, pg. 3).
