Mains Power Analysis
Mains power wiring is checked for devices that use such circuts as "Transmission media",  we check for both carrier current and sub-carrier surveillance devices.
All electrical devices with the suspect area are activated & deactivated during this test to ensure that none are radiating these types of transmissions.

Redundant Wiring Analysis

 

As well as testing the wiring that is utilised, we also trace all redundant wiring for eavesdropping devices. The use of redundant wiring is favored amongst professional eavesdroppers for transmitting / receiving media from their listening devices.
We would also recommend the removal of all redundant wiring in high risks areas.
