Spy-Spot Investigations specializes in the sweeping and detecting of eavesdropping equipment. We can detect the infiltration of your telecommunication system as well as the interception of verbal conversations in both your home and business.

Spy-Spot Investigations provides quick and simple setup of TSCM (Technical Surveillance Countermeasures) service on a one time, periodic or contractual inspection basis. We utilize over $100,000 of the best and most advanced field proven spy equipment and TSCM gear on each and every assignment.

The equipment we use includes the following:

1. A radio spectrum search for actively emitting radio frequency (RF) devices in the range of 9 kHz to 21 GHz using OSCOR 5000 Counter Surveillance Receivers.

All suspect radio frequency emissions, including video carriers, are examined and demodulated. This equipment is also designed to detect eavesdropping devices that are being masked by stronger legitimate radio stations (“snugglers”). As a further option the Oscor will display any images transmitting from hidden video transmitters within the search area. The radio signals intercepted are displayed and a graph of the received spectrum produced. All signals are then identified as either emanating from a legitimate transmitter such as a local broadcasting station or originating from outside the area under investigation. At this point the radio spectrum “signature” is stored on computer disk for future reference.

2. A selection of wide band counter measures receivers are used to measure the RF field strength and detect eavesdropping devices that use directional antennas.

3. An electronically enhanced physical search is made of all wall, floor and ceiling voids, and furniture and object d’art, within the search areas using an ORION Non Linear Junction Detector together with a Locator Military 888 NLJD. This equipment is designed to detect any passive electronic surveillance device, either hardwired or remotely controlled regardless as to whether it is switched on or off. The NLJD is also used to detect hidden pinhole cameras.

4. A detailed physical search of all fixtures and fittings including desks, filing cabinets, and pictures frames, calculators, electronic office equipment etc. At this point notes will be made regarding exposure of confidential papers, locked desks and filing cabinets, available document destruction processes, access control systems, etc.

5. A physical and electronic inspection of all electrical sockets, power and lighting circuits and cable ducts within the designated search areas, using a range of physical search aids and radio receivers with enhanced very low frequency (VLF) capability to detect mains carrier devices. Transparent tamper evident seals are placed on the equipment where possible to prevent possible unauthorized modifications.

6. A physical check of the external areas is carried out where possible to determine whether any eavesdropping devices have been placed on or near the location.

7. The vulnerability to attack by remote eavesdropping devices, such as laser or boom-type microphones is also evaluated at this stage.

8. Telephone instruments and all ancillary equipment are physically examined. All telephone lines and accessible telephone wiring, including the terminal boxes, distribution points (DP) and main distribution frame (MDF) are electronically tested and compared with the known values for that type of system and telephone exchange.
