Bug Detection and Counter Surveillance Services

Initial Survey and Assessment

You've got questions. We've got answers. Call 1-866-629-3757 to speak to a private investigator or security consulant.Jennings Smith’s specialized team of Bug Detection and Counter Surveillance experts will conduct comprehensive and systematic electronic sweeping processes and methodologies designed to detect hidden listening devices; cameras, transmitters, tape recorders and other illegal devices in businesses, homes, laboratory and research and development facilities.

The REI equipment used by our specialists represents the state of the art and is a microprocessor controlled counter surveillance system with a custom designed built-in spectrum analyzer that can operate automatically storing all encountered signals in memory for detailed review. These OSCOR units will detect all major types of audio and video RF transmitters, including carrier current and infrared. A discrete trace analysis of each electromagnetic emission received will be conducted in the suspect area from 0 KHz to 12 GHz, equating modulation received with a non radiating sound source located in the suspect area. Included will be power line carrier, sub carrier and infrared transmissions. This new detection technology is called Trace Analysis and will be utilized for identifying and locating RF signals associated with espionage related surveillance devices.

Counter Surveillance Inspections

Our team will also deploy Sweep Unit Counter-Surveillance Probe/Monitor, a broadband receiver designed to detect and locate all major types of electronic surveillance devices including room, phone, body bugs, video transmitters, and tape recorders. The equipment used by our specialists offers a Multi-Functional Utility i.e. with probes to detect RF transmitters (audio and video), carrier current transmitters, and telephone bugs. The Probe is also available to detect for infrared transmitters, tape recorders, and acoustic leakage. The equipment employed reveals high Wideband Coverage with no holes or gaps and features an auxiliary audio input, which allows listening to telephones or lines for “hot mikes,” hook switch by-pass and “infinity” bugs. It is very effective for rapidly detecting and locating transmitted signals. All naturally occurring transmitters (police, fire, HAM radio, etc.) as well as any other transmitter sources identified at the time the search will be conducted, these frequencies will be checked and stored with reference notes in a database for future cross reference purposes. AC power lines and switch box receptacles along with telephone lines will be also monitored.

Infrared Thermal Imaging

All room areas including ceiling and wall areas will be examined and subjected to infrared thermal deviation analysis utilizing a new FLIR i7 infrared thermal imaging camera. This camera will reveal hidden (behind walls, smoke detectors, sprinkler heads, etc.) transformers powering mini-CCTV and switched devices. Wi-Fi 2.4 GHz access port signals will be searched and analyzed. An audio contact amplifier will be used to evaluate the potential for “through the wall” over-hears along with NLJD searches where necessary for non-operational devices.

Telephone line Listening Device Analysis

During our All of the telephone lines will be inspected with an ISA ETA-3A electronic telephone instrument/line analyzer, in addition to inspections utilizing a Harris TS 25D test set with Harris Pro2000 wire probe and an SC8108 TDR network cable tester. These tests consist of off hook/on hook voltage tests, an all wire listening test which examined every wire in the telephones and conference call units for possible modifications which would allow audio to pass while the telephone is on hook, in addition all lines will be checked for infinity type devices and polarity negating circuitry then ground balance and resistance bench marks will be compared and registered in the database for future cross reference. Infrared carrier emissions will be examined. TDR (time domain reflectometry) tests will be conducted to reveal possible taps in local telephone wiring. A thorough physical inspection will be also conducted on each electronic instrument and its connections for any additions, which could possibly transmit conversations (audio).

All areas/rooms/offices will be inspected both visually and with highly sensitive metal detection equipment using a scanner operating at 13 khz/6,600hz for non-operating or switched tape recorders and or transmitting devices.

Hidden CCTV Camera Detection

All areas/rooms/offices will be inspected for non-operating or switched CCTV cameras and mini DVR recorders and or transmitting devices. We use pulsed high power LED beam arrays to detect hidden camera lens in addition to the FLIR i7. This method is very effective in locating hidden cameras. Methodology: our hidden camera detector/locator is the most reliable technology available for making sure that private actions are not being watched. Its function is based on the principle of optical augmentation. This technical jargon refers to the phenomenon where light reflected from a focused optical system, such as a video camera, is reflected along the same path as the incident light. This means that if a hidden camera is illuminated and viewed with our camera finder technology, then a strong reflection from the target camera will reveal its position to the technician.

Finally, a complete physical search, including all, fixtures, furnishings, ceilings and surrounding areas, as well as any existing electronic/computer equipment will be conducted to identify any non-switched listening devices and or voice recorders.
