As to serveilence cameras, is anyone familiar with methods of not getting photographed in the first place? Some methods I've heard of: 1) spray paint or vasoline on the lens (kinda obvious :) 2) putting a pin or finnishing nail in it's coaxial cable (umbilical if you will) - how good of a job of scrabbling the image will this do? 3) mounting a "test pattern" in front of the lens. 4) placing a magnet on the side of the camera (does this work?) 5) timing the pan, and taking advantage of "dead areas" (areas not covered for brief periods). Anyone familiar with the general range/resolution ratio, and how wide an area will get covered? Any other methods?
