I gotta admire the british sense of humor....here's the short spot.

 

There is a guy posted and asked about  "TV License People Can Detect TVs from outside your house, how? The question is basically in my title:
TV license people can detect TVs from outside your house, how? What technology do they use for this?", found at whatever discussion forum called "digital spy" when I was shuffling on the Internet.

 

one of answers was followed: "They put a glass against the wall and listen really carefully"...lol

 

TV license is one of ridiculous taxes that people have to pay if they want to watch any kind of programme, channels received through televison in the UK, and the regulation has just been upgraded and extended that people who watch TV online as it's being broadcast have also to pay or "buy a TV license". 

I was watching BBC NEWS online broadcasting while I found about this notice....

 

For those who refuse to buy a TV license but watching TV at their home slinkingly. TV license people do have the technology that can detect the unpaid TV signal and find your location, knock off your doors or holes with police officer to force you to buy a TV license or confiscate your little box that can generate the image and sound. That's the reason of the question being asked above.
