Aerotec’s teaming partner for airborne infrared inspection of electric power transmission facilities is HOT/SHOT Infrared Inspections, Inc.

Typically (for airborne data capture operations) HOT/SHOT will provide both the airborne infrared camera equipment and a qualified operator while Aerotec provides the helicopter and flight crew, mission planning, and logistical support.

Typically (for results processing), HOT/SHOT will provide the qualified operator/interpreter of the infrared photography and the report generation while Aerotec provides the data processing necessary to a) geo-reference the infrared video and b) present the geo-referenced video/results in an interactive GIS-browser access environment.

The HOT/SHOT infrared equipment used may be generally described as follows:
The FLIR Systems 2000F infrared camera has a thermal resolution of 1/10th°F, and a pictorial resolution of 525 lines per frame (560 CCIR) with 352 elements per line (428 CCIR). It utilizes a Mercury, Cadmium, Telluride, (HgCdTe) 2x4 TDI detector array, with an IR spectral bandwidth of 8-12 microns. It renders an image of an object's thermal emissions in shades of black to white, with white representing the hottest portion of the image. The data is then recorded on S-VHS data disctape for later processing. The thermographer inside the cabin remotely controls the camera, mounted externally on the helicopter. All system operational controls are adjusted with the hand-held system controller. It contains output signal gain and level, and cage, which returns the camera to a pre-selected azimuth and elevation. LCRS rate stabilization, assisting the thermographer in manual target tracking by dampening the effects of aircraft motion, Field-of-regard (azimuth +120° to -120° and elevation +30° to -180°), Field-of-view (wide [1X] 28° x 15° and narrow [4X] 7° x 3.75°), image polarity, focus, and system power, are also remotely controlled.
