Infrared Bug Detection – Thermal Emissions Spectrum Analysis ™

(TESA ™)

Infrared Bug Detection of a Ceiling Tile

Infrared Bug Detection, or Thermal Emissions Spectrum Analysis (TESA) is a sensitive infrared detection technology. Our instruments sense and visually display temperature differentials. This advanced technology gives our technical teams the ability to easily find hidden surveillance cameras and other devices during the evaluation process. Here’s how it works.

Whenever electricity flows through a circuit, some of the energy is lost in the form of heat. Sometimes you can feel an electrical device heat up, like your mobile phone or laptop. Human touch, however, can’t detect subtle heat losses. We can only detect about a two degree change, besides touching everything to detect bugs is not practical, especially ceilings.

All electronic devices emit heat, but very small electronic surveillance devices only generate s scant amount of heat. It requires special equipment to detect it. Although your sense of touch can’t detect this microscopic heat gain – a thermal camera can. Thermal Emissions Spectrum Analysis can also reveal density differences in materials, thus revealing hidden compartments, and construction alterations.

Thermal Emissions Spectrum Analysis - Infrared Bug Detection of a Clock Radio Our laboratory grade Infrared Bug Detection (TESA™) instrumentation displays these microscopic heat differentials. This advanced technology allows us to find hidden surveillance cameras and other devices, without any property damage. In fact, whole rooms can be quickly scanned for operating devices, and even recently turned off devices will be detected — heat takes a long time to dissipate.

Thermal Emissions Spectrum Analysis Bonus

This technology has allowed us to alert clients to unseen disasters-in-the-making, on several occasions. Examples include: electrical device overheating, and water leaks from roofs, pipes and air conditioning systems. This spared them from more than just eavesdropping. Fire, flooding and the need for mold remediation come to mind.
