TSCM Bug Sweeping Equipment

A TSCM bug sweep is the process of detecting electronic monitoring devices. This is a service most often offered by technicians in the private sector.

  • As expected, a lot of expensive and technical equipment is required to perform a bug sweep.

Furthermore, bug sweeping is a highly technical and specialized field in the private industry that only a few technicians are capable of performing correctly. A lot of skill and experience is required to operate the very costly instruments.
