A:Answer I took my phone and camera to the area I wanted to mount it. Held it in place to see what kind of signal I had. The Wi-fi shows 4 power bars and the worse one I have is 3 bars. That's 60 feet away and through 3 walls. I have another that is 60 feet away but the front wall of the house is the only obstruction, it shows full strength. The third camera is about 50 feet, goes through 4 walls and it has 3 bars.
