my wife's cousins have 3 security cameras around the front of their house. the cameras have led lights built in and you cant even tell when they are on, the one right above their front door has a zoom and all these are connected to a mp recorder that re-writes itself when memory is full. you want to talk about evidence.
I thought about getting the same set-up. I thought they said the kit was only like $199 for 2 cameras and they paid like 49 for the 3rd. of course they did the labor themselves.
