CGI is a serious issue. That concern is resolved however with the proper solution.
A street has 100 businesses on it with 100 different and separate security systems recording to privately controlled, not networked, DVR. Something bad happens on that street. Are all 100 separate systems going to be CGI altered? That's highly unlikely.
Cameras are not just regular visual light either. The person would have to fool infrared, thermal, low light, and regular cameras. They would also have to fool systems not based on cameras (magnetic, motion, temp, etc.) as well.
Speaking of communities, I believe you've seen my post about this, @theblindsquirl. It is directly related to this post, or I wouldn't be sharing it here. :) Thanks!
It still seems to me like people are far too willing to give up any right to privacy for the illusion of security.
We have privacy in a public place? Inside your home, sure, but on the street and in the play ground down the road? My children are playing there. I'd rather have cameras and people watching them for their safety.
