I know someone who had thier travel trailer stolen from thier driveway , and they caught the thief on camera . The police officer that came out to make the report looked at the video , but didn't even want a copy of it . He asked the people if they knew the guy , and they said no . He said "neither do I , what do you want me to do drive arolund and look for the guy ? " The camera does not mean you will catch whoever is on the video , but alot of people will not mess around if they see that you have cameras . I have them on my house , but more as a deterent than anything .
