I need to know the size of the sc rew on the bottom of the video doorbell pro. I installed it directly on the front door, and the suplied screw tool is too long to tighten the screw. I can get an allen style tool to tighten it, but I need to know the size.
I may end up relocating it if I can convince my electrician to add a transformer for me. But for now, I still have to take it off and charge it.
