I think people sometimes don't fully understand the complexities of actually catching a bad guy doing something bad. We see these videos on YouTube and think its easy to catch crooks. In reality, its very hard.
If you have a big area to cover, you need many cameras. A wide angle lens isn't going to give you the details you need. There there is the problem of night, having a high enough resolution, not having the camera distroyed by the bad guy, and maybe the biggest problem, how to find the one or two frames with the crook, from the millions of other frames.
I had two camera into a timelapse VCR in my previous house, and had several crimes, but never caught anything on camera. Either it was too dark or far for the camera to see, or I could never find the incident in weeks of months of tape when I didn't know exactly WHEN it occured.
Technology is getting better, but the fact of the matter is to catch a bad guy on tape with a non-human monitored camera, and hope to have a good enough image to catch the person is pretty hard. I'd either spend a bunch of money to get the best stuff, or don't bother and just add some additional outdoor lighting, motion detectors, etc.
