One time, when we were dealing with a bad neighbor, I set up a old, unreliable flash trail camera in a fairly visible spot and then a new well concealed infrared unit focused on that one. Thought might catch guy on video stealing first camera and get him for both trespassing and theft; but never caught him on either. Apparently, one of the short periods during which he behaved himself.
