We have a range of detection tools at our disposal in our vans.
Some aspects of the equipment have been developed in such secrecy that engineers working on specific detection methods work in isolation - so not even they know how the other detection methods work. We are able to tell you that the detection equipment used by TV Licensing takes as little as minutes to work and can distinguish between two television sets close together on either side of a partywall. Our detection equipment is able to operate from up to 60m away.
This gives us the best chance of catching licence evaders.
