The data is then recorded on S-VHS of Hi8 video tape for processing. The camera, mounted externally on the helicopter, is remotely controlled by the thermographer inside the cabin. The controls contain output signal gain and level, and cage, which return the camera to a preselected azimuth and elevation. LCRS rate stabilization assists the Thermographer in manual target tracking by dampening the effects of aircraft motion. The FLIR camera, unaffected by solar glare, can perform your powerline survey in the heat of the day, any time of the year.
