Build your own weatherproof setup and run long cables to camera too…
The power Supply mounts indoors but the cable to camera can be longer as the 5 volts is regulated at the camera.
I have ran over 180 feet of 2 conductor cable to camera with this setup, use low voltage lighting wiring it can be buried, it is weatherproof and UV resistant.
Connect the 12v to 5v micro-USB regulator adapter to cable matching polarity ( +red -black ) along cable where a camera is needed if more than 2 cameras just get a 12 volt adapter with more current (Amps) The Adapter regulator is weatherproof except the micro-USB itself but the boot on the V3 takes care of that.
