Construction and setup of the owl box – a solar charge controller and power supplies are in a shed next to the box. Original Steve Simmons box design is based on the Feb 27, 2012 article “Build a Barn Owl Box as shown in the picture of the cover page below. My version adds a partition for the cameras. The wired POE cameras in the box are routed to the shed in conduit. The shed power cabinet contains the 12V battery/charge controller and buck boost power converters to power the 24V TP-link 5.8GHz wireless data link and 48V POE camera power.
