Tv detector vans....?
Answers: i dont see how they could work, it's adjectives on computer these days(if you dont have a licence)
i seriouslt doubt it
although, they can pick up a tv signal, they cannot relate what channel you are viewing far smaller number see it!
as far as i know they cannot detect a computer screen surrounded by your home, as it is not recieving/sending airwaves which is what they detect.
no they can do neither.......how do i know... let's just utter i'm in the detection business. Phreaking in opposition is possible but you have to be contained by extreme cose proximity to the monitor/ tv
Detectors cannot detect which channel you are watching on a laptop, just that your notebook is receving a tv signal.
your right they can...they can also see what underwear your wearing
Yes, that was probably the earliest method of 'hacking' employed by industrial spies.
Early VDUs weren't shielded worth a damn, so it be quite practicable to sit out an office block and tune surrounded by to a radiated signal from a VDU and see what be going on.
TV detector vans are a waste of space. They are maketed to terrify people into buying a tv licence. They can't fastener you with one of them, it's adjectives a load of rubbish...
No, because you are not delivery the pictures via the airwaves. With your TV you are. Also they only check those houses which own no licence. In this age of computers any house without a licence is graceful to spot on their records.
Yes - TV detector vans are notably sophisticated. They go to a road where on earth all but one or two enjoy a TV license. They park the van up, get out, look to see who have TV Aeriel's then travel to the houses without license and peer through the letterbox or window to see what the associates inside are watching before knock on the door.
TV detector vans are a bit of a myth. The technology behind detection is finding the signal from the hetrodyne heir in the TV. It is a frequency a TV produces to give support to demodulate the AM signal of the TV's picture signal. This signal can carry across to the Aeriel cable and can be see with an oscilloscope and supposedly TV aerials can transmit this frequency so the 'vans' can pick it up. However, the signal is especially weak, an Aeriel will transmit any signal really poorly and by the time the signal is transmitted at hand would be so much interference it would be impossible to detect. Plus, AM/FM modulation is no longer used in digital systems, so the unbroken 'detection theory' can no longer be used!
