New Technology

A new important tool in a sweep is Infrared Thermography.  Our thermal imaging camera is used on all sweeps to detect the infrared heat signature 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 also emit or radiate  infrared energy.  This energy is not based on reflectivity of the object or on its color or intensity; it is based on the temperature of the material that makes up the object. 

Listening devices create a small amount of heat as electricity powers their circuitry. Even very faint amounts of heat are visible against the normal infrared background that the thermal imager detects, making it possible to find devices hidden in wall cavities or built into furniture and furnishings.

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 new technology can find.

Ceiling Visible.jpg (3317 bytes) The picture on the left shows a view of an office ceiling in visible light.  The picture on the right shows the same ceiling viewed using infrared thermography.  The white spot in the highlight reveals the presence of a chip camera hidden in a ceiling tile.

 Infrared Thermography reveals the presence of a small RF transmitter built into a speaker enclosure of a stereo.  The highlight shows a hot spot in the lower lefthand corner of the speaker

Wall Visible.jpg (4291 bytes) This view of an office reveals the heat signature of a radio transmitter in the wall behind the bulletin board. The highlight indicates the faint hotspot caused by the device.  Sometimes the indications are very subtle, but a skilled operator will not overlook them.

Conference room visible.jpg (5937 bytes) Thermal Imaging not only makes a sweep significantly more thorough, it can save time, too.  The photo on the left shows a view of a trashcan in a conference room.  The IR image shows the CCTV camera and transmitter built into a false bottom.

Wall Cavity Visible.jpg (3427 bytes)

 Thermal imaging is also used to located cavities in walls and other objects where devices could be or could have been hidden.  The picture on the left shows a wall in an office.  The IR image reveals a cavity in the wall.  It appears as a light colored rectangle.
