"Bug detectors"

There are many bug or signal detectors available on the market, indeed they are relied on by some search companies and are often used by private individuals. There are two problems with relying on one of these. Firstly more than 50% of bugging devices on the market are designed to go into a sleep mode (stop transmitting) when whoever has placed the bug is not actually listening, and so it is unlikely that they will be detected at the time of the bug sweep.

Secondly there can be 20 - 50 transmissions in many houses or offices and often more; these will come from legitimate sources within the building, but will also come from radio stations, taxis, or other houses or buildings nearby. A signal detector will detect many signals and will not necessarily be able to determine if they are safe or are bugging transmissions.

We use modern and sophisticated system equipment which is able to reliably detect and locate active (transmitting), and non active (not transmitting) bugging devices in addition to the latest threat of GSM devices. Bug Sweeping equipment used includes non linear junction detectors, sophisticated spectrum analysis, signal analysis software, near and far field signal detection and location, video detection, thermal cameras, and specialist GSM bug sweeping and location equipment.

Home Bug Sweeps

No home is private if someone is listening to or watching your every move. Spying or bugging devices for little more than a hundred pounds can pass your private conversations, movements or computer data on to indiscriminate third parties.

Vehicle Bug and Tracker Sweeps

A vehicle tracker can pass every move you make, and every place you visit, on to someone else with pinpoint accuracy. Trackers and mobile vehicle bugs can also be used to listen and transmit private conversations held within the vehicle.
