A TSCM sweep or inspection involves three phases:

  1. Scanning a series of rooms or a space for hidden devices that transmit via a range of frequencies to firstly generate an RF spectrum footprint of the area and then to examine RF spikes to enable them to be identified as safe.
  2. Physical and technical inspection of electrical devices, telecommunications and IT systems are undertaken to search for hidden “hard-wired” microphones and or covert cameras. The in depth inspection of telecommunications devices, includes each handset and socket; through to internal and external exchange levels.
  3. Walls, floors, ceilings and ducts are all inspected and scanned for any hidden, redundant devices or wiring.
