A new important tool in a sweep is InfraRed Thermography. Our themal imaging camera is used on all jobs to detect the heat signatures emitted by listening devices.
Here's how it works:
Visible light is reflected from the surface of objects. This appears to your eye as color and brightness. At the same time, the objects you see radiate infrared energy. This energy is not based on the reflectivity of the object or its color or intensity; it is based on the temperature of the material that makes up the object.
Electronic devices create a small amount of heat as electricity powers their circuitry. Even faint amounts of heat are visible against the normal infrared background that the imager sees. This makes it possible to find devices hidden in wall cavities or built into furniture or other concealments.
In our mission to provide state of the art service in detection techniques, we continue to use the latest in emerging technology to enhance our capabilities. Infrared Thermography is another valuable tool; not inexpensive, it demonstrates our dedication to doing the job to the best of the ability of our technicians and technology.
Take a look at the photo gallery for highlights of what this technology can find.
