I do have security cameras up, after a rash of thefts around my neighborhood to the vehicles I put up cameras to find the pattern as they were hitting the area at what seamed like once a week, I got jacked like 3 times.
So I put empty .45 cases in my glove compartment etc (all the areas they went through) and watched the cameras waiting to find the pattern to catch them but they got caught before I got anything on camera.
But now I use the camera to keep an eye on the kids, and I've even nailed some kids egging the house, one of which I gave their mother a copy of the video (he was in the hot sun scrubbing egg for hours
)
I even managed to get video of an attempted robbery of a neighbors house, the neighbor knows I have cameras so I gave them a copy of the video.
If you have video, even if you dont' get the plates you get more information such as number of people, male, female, black/white/tall/short/fat etc and the EXACT time it happened.
Most of what I see on my cameras is kids being stupid kids, some of it I have to laugh at. One morning I woke up and every trash can down both streets was knocked over and trash spread all over with some cans as far away as two houses down. So I pulled up the video and saw a car full of kids driving down the street ramming the trash cans with their car at a fairly high speed!
So yea, security camera may not be the smoking gun to protect your property, but they can give you additional information, and be ammusing at times.
heh, all this and I don't live in a bad neighberhood, city life I suppose.
