Summary: Worked for POE outdoor Trendnet cameras, but had to replace power supply on one after 4 months. Might have been environmental though as it was in an outdoor weatherproof enclosure in direct sunlight in Florida.
Summary: We have found that in some cases the run of the mill 4 port PoE switch doesn't quite push enough power to the EnGenuis units we install. Additionally, using an injector allows us greater flexibility in placing what we are powering as we get some extra length.
