Default Can a TV camera be blinded by IR?

A friend of mine has a neighbor who has stuck a small video camera in
his bedroom window to spy on the friend's yard. The problem is in
clear view of the camera is the friend's 14 year old daughter's
bedroom window. The neighbor claims that the friend is running an
illegal business out of his home and the camera is there to try to
catch him at it. My friend hasn't tried to get the state police
involved yet but the local town cops won't do anything about it.

Anyway I had an idea. I keep a small B&W TV camera in the shop
connected to a monitor which I use to check IR remote transmitters.
When I hold a suspect remote a few feet from the camera and operate
it the camera is essentially "blinded" by the otherwise invisible
infrared pulse train. Can something like this be done cost
effectively but naturally on a much larger scale to blind Bozo's
camera? My friend got ****ed off one night and sat there with a laser
pointer directed at this camera for a couple of hours. Although it
didn't resolve the problem, it did bring the cops down to advise my
friend that he couldn't do that without violating the neighbors
privacy! Makes you question the definition of "freedom". The
distance looks to be about 200 feet. Thanks, Lenny.


Sounds like this neighbourhood war has been going on for quite awhile,
and this is just the latest episode. Sometimes the only solution is to
move, and be nicer to the next set of neighbours.
