Reversing Polarity On a Television...?

True the Vidicons used a different type of phosphour.. a photo electric reactive type.. my theory on that is now a bit rusty....

I challenge though..

All this was superceded by the invention of the CCD, ...... This lead to the invention of video cameras, and TV cameras adopted them once the quality became good enough.

Video cameras (that is home/domestic) using Vidicon/plumbicon tubes were around long b4 CCD's and certainly CCD's allowed the domestic video camera to reach the pocket of joe average.. CCD's made adifferance as Domestic Video Cameras started to go mainstream..

So theoretically if you modified a small black-and-white telly a bit, stuck an absolutely huge lens on the front (a good distance from the screen) and hooked it up to the appropriate electronics, you could make it into a camera.

kill joy... but you are correct.. there is another problem.. the EHT in a television is (and worse in the newer sets) horrificly noisey/unstable this would make such an idea almost unworkable.
but it was just a thought..

signal leakage is how the TV licencing authority in the UK catch people without a licence in this country they pick it up with a reciever, then send you a big fine.

VEry true jinxy,

It is also how the same authority's are able to tell if you have recieving equipment listening to the wrong stations.. ie mobile phones, cordless phones.. radio scanners have very distinctive signatures.. hmm
I wonder what the leakage profile/signature of 802.11x receivering equipment is like? a methode to tell if some one is sniffing your 802.11 network..
Hey this thread has bounced into the realm of computer security..


Cheers
