A detailed physical inspection is performed in all areas under investigation. The search includes all drop or feature ceilings, floor coverings, furniture, electronic appliances, and other general office equipment. Particular attention is paid to acoustic leakage to adjoining areas and rooms
The wiring exiting the areas under survey is visually inspected and electronically tested to verify that no room audio is present on the wires. Room surfaces are also examined with Non-Linear Junction Detectors (NLJD's). The NLJD is a microwave device that detects active or passive electronic circuitry that may be hidden in furniture, walls, ceilings, etc.
Sweepteam is able to detect inert or dormant, as well as active surveillance devices. New developments are continually reviewed to maintain our superior detection capacity.
