Project Profile: Going the Distance with PoE

PoE-enabled Ethernet extenders change the game for IP-based security installations


Although the PoE Plus standard doubles the power that PoE devices can deliver, from 15.4 watts to 30 watts or higher, opening the possibilities in deploying PoE on access control devices, some still see PoE in the security industry as a fairly new concept.

“The security industry is just starting to move into this Ethernet PoE world and they are the ones that are going to benefit the most from the new PoE Plus standard,” said Tullis. “But it’s going to take a while for the industry to get ready for these new possibilities.”

HOW IT WORKS
Installing a PoE-enabled Ethernet extender kit is simple. Using the kit Tullis deployed, the Enable-IT 865 (PoE injector included), for example, the installer only has to connect their Ethernet cable to the PoE injector’s “IN” jack (RJ-45), then connect a short patch cable from the injector’s “OUT” jack to the base Ethernet extender’s LAN 1 port. This base extender (the CO unit), which does require 9VDC (wall adapter included), or can be powered from a properly sized PoE switch, sends the data and power over the same category-rated cabling from its “Interlink” port to the “Interlink” port of a remote self-powered “CPE” unit up to 2,500 feet away (up to 3,500 feet when only sending data). From there, you simply connect a PoE device, like a PoE IP camera to the remote/CPE unit’s LAN 1 port and you’re in business.
