The Counter

Technical Surveillance Countermeasures involves the detailed physical and technical inspection of the working environment, or home, to locate and neutralise covert surveillance devices. A TSCM inspection is targeted at preventing, as well as detecting, the unauthorised and illegal interception and subsequent disclosure of sensitive information.

Artemis Security Solutions Ltd adopts an intensive and thorough approach to TSCM. A thorough TSCM programme will protect against all the bugging devices that are for sale at the above web sites.


Artemis Security Solutions LTD only employ former Government service signal analysts to conduct their TSCM work. These are the only individuals with true in depth and all encompassing knowledge of the signals environment.

Unlike many other TSCM companies we do not believe that the bugging threat ends at 5 Ghz, the limit of the Scanlock M2. We sweep up to 18 GHz, which involves the use of sophisticated and expensive spectrum analysers. Most other TSCM companies are reluctant to make this sort of investment.
