TSCM Technical Surveillance Counter Measures Experienced NVS engineers will implement a "sweep" of the target area to pre-specified parameters. Following 10 years experience of deploying surveillance equipment, NVS have the experience to offer this counter surveillance service to investigate and search for intelligence devices, e.g. cameras, bugs and wiretaps. A technical operative will sweep for live RF devices from DC up to 11GHZ, IR frequencies, and check wiring for covert signals. A physical operative will sweep the target area in very "hands on" manner looking for dormant or dead devices. The operative will search under floors, above ceilings, in the fabric of the building and within objects in the target area. Our TSCM Specialist has over 20 years experience in RF manufacturing (HF, VHF, UHF & Microwave) combined with service in the telecommunications industry and latterly specialist in the design & manufacture of covert video/ audio surveillance. Systems are available for hire or sale to industry. New technology is constantly being exploited by the people who deploy these eavesdropping devices, making each sweep unique. Therefore a bespoke service is required.
