I'm not a fan of a security camera society, so I won't get one personally, BUT when we were having an issue with some kind of rodent trying to claw its way into our house, above the front porch, I got a couple sonic rodent things. One is plugged into the porch outlet, and has a blue ring light that looks identical to one of the cameras. Chick's happy we got some camera looking device out front, and the rodent went away.
Whether you go with the camera or not, a well-positioned sprinkler setup and a remote control can provide hours of entertainment.
