Review on Dualcomm POE Over Coax Adapter Kit DECA 200 by Walter Martin

Currently used to power the Ubiquiti G3 dome camera. Initially I had trouble getting this to work as the camera would not turn on when plugged directly into the adapter (same for mode A and B). But after some trial and error I realized that there is a compatibility issue with the camera, probably in how the camera determines whether to use 802.3af or passive 24V. It finally worked after adding the Ubiquity Instant 802.3af adapter between the mode B adapter and the camera. So the order is: Ubiquity POE switch > Mode A adapter > Mode B adapter > Ubiquity adapter > G3 Dome. The Unifi video program was able to see and receive the camera immediately.
