The Mini Inspector Robot is a video inspection tool that provides documentation of the interior of air duct systems and other hard-to-reach areas, says the company. The unit features a color video camera with wide-angle lens, 75 ft of cable, and a 6.4-in. color LCD video screen for instant viewing of interior surfaces. The user just plugs in a VCR to record all the action. The industrial case holds all the components, making this a compact marketing tool, the company says.
