I thought I'd post some peak wattage info which might be useful. I got this from FCC ID Search which allows you to enter the FCC ID number found on the back of any RF device to get wattage info. PVT581 controller: .059 watts NPVT581 controller: .062 watts RE500 extender: .0317 watts RE700 extender: .0703 watts FC200 camera: .011 / .031 watts* There are two values for the camera - I am not sure why. It might be that since we know we can adjust the signal strength (dBi) of the camera, the first number is default and the second number is max strength dBi. Just guessing.
