The team has the latest advanced professional passive and electronics counter surveillance equipment to search for and locate surveillance devices or 'bugs'. The sweeps include searching and locating Infra red, video, burst, encrypted, spread spectrum and frequency hopping transmitters. This covers serious professional bugs, not just ‘domestic’ transmitters that can be purchased by anyone at ‘spy’ shops in London.
