Unfortunately there isn’t just one piece of equipment that detects all listening devices on the market. Depending on your situation and your environment there could be 5 or 6 individual pieces of equipment required to detect a type of listening device. It’s a highly technical field requiring experience, knowledge and knowhow on types of devices, how they are installed and whats available in the market.

Site survey’s are an essential service for (debugging & TSCM) to identify and locate illegal eavesdropping devices on the higher end of the scale. Our TSCM surveys are conducted using meticulous risk management procedures along with the latest military equipment available in the world.

We survey the spectrum externally prior to conducting comparative analysis in offices, boardrooms, homes of executives and other personnel where sensitive discussions are often held. Luke Athens performs the surveys with professional equipment.

We can create customs antennas with the Oscor 5000, omni spectural correlator to help locate burst/packet listening devices, which are one the most difficult devices to detect apart from bluetooth listening devices. Custom antenna’s will help scan the environment over 100 times quicker to ensure even the most sophisticated device in the market will be detected.

International Intelligence Agency offers VIP protection programmes, provide secure environments for special meetings and offer workshops on the threat of eavesdropping devices to management to help educate companies on what are the latest threats in the world. We regularly consult companies regarding their security needs, including prevention measures, encryption for mobiles, land lines, word documents and or storage components. Our general risk management solutions minimise theft and maximise site security.”Prevention is the cure”

Our technical surveillance countermeasures survey’s may include the following investigations and analysis :

FULL SPECTRUM ANALYSIS FROM 10KHZ TO 21GHZ

We offer various options depending on the threat level and we are capable of performing a spectrum analysis up to 21 GHz. (21 000 MHz)

We analyse, detect and locate all types of transmitting devices including electro-magnetic radiating devices, video, or data signals, including free to air transmissions and devices that utilise the power lines, ac/dc as a transmission source. Special probes and procedures are used to identify sub-carrier and spread spectrum RF analyses.

Our state of the art instruments are combined with a computer controlled spectrum analyser, a spectral correlator, and broadband receivers to analyse, detect, verify, locate and demodulate all radio frequency (RF) signals. The Oscor 5000, omni spectrural analyser allows the tscm operative to hear and see the signals detected. This function is imperative in circumstances where it is difficult to demodulate signals, such as digital signals. Digital signals are encrypted therefor unable to listen into the transmittions without the demodulation key. There are millions of types of demodulation keys and it is impossible to be able to apply demodulation in reasonable time frames. This is why a site survey is essential prior to the detection process, most signals today are digital, such as mobile phones, radio, television. It doesn’t leave much for the operator to demodulate. The oscor will use comparative signal analysis along with signal strength processes to detect digital devices. Once this has been done we can be satisfied with our results and outcomes.

The detected signals are stored on our computer’s hard drive for future surveys and comparisons. Conducting a RF sweep without a spectrum analyser can be compared to trying to make a phone call with no numbers.

Telecommunications Systems Analysis

We are capable of testing digital, electronic and electro-mechanical single and multi-line telephone sets and lines for devices and modifications which would allow the interception of room audio and telephone conversation.

Tests include the use of Single and Multi-line Telephone Analysers designed to detect all known threats.

We also test telephone lines and cable pairs for all known wiretapping techniques or cable pair modifications that would allow for the interception of telephone conversations and room audio. Tests are done to reveal all wire irregularities, including parallel bridge taps and split/resplit inductive wiretaps.

Telephone frame rooms and distribution panels in the area of concern are physically and electronically inspected. The equipment used is compatible with all three generations of telephones, electro-mechanical, electronic and digital systems.

Physical Inspection

A thorough physical search is performed in the areas under investigation. The search includes all crawl spaces, drop ceilings, floor coverings, fixtures, appliances, and office equipment. Particular attention is being paid to the areas adjoining the rooms that have to be secured as well as the walls between the areas.

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. Depending on the size of the area more than one NLJD will be employed.

The testing procedures during the physical search also include the detection of active or inactive infrared, light or ultrasonic and microwave transmitters beyond the range of the RF analysis.

We also use a variety of multi-meters, scopes, flashlights, ladders and other instrumentation necessary to perform a thorough physical inspection.

Analysis, Report and Recommendations

At the completion of the survey a comprehensive report outlining the work performed, results, record of findings, readings/measurements, as well as our evaluation and recommendations are furnished.
