My girlfriend had me put up a Ring Doorbell. It is the recharge type and is not wired to the doorbell. We only have it sending to the apps we have on her phone and my ipad. It works great and is very clear with the video. The only think I don't like is the sensitivity seems to change. One day it will catch every car going down the road and other days nothing, but I'd rather have it too sensitive than not enough. We've had 2 questionable people come around when we were at work and ring doorbell and look around suspiciously. The video of both of them is clear as a bell and would be very easily to identify to the cops. At night, it is clear, but not as clear as daylight of course. It would be a little harder to identify someone but I think it would be fine for the cops. I would have to say overall I'm pretty impressed
