ROTO-VISION TM
The Roto-Vision Video Inspection System is designed to provide instant video footage of remote locations. It can be used for inspection of HVAC systems and air ducts for leaks, cracks, and contamination. The Roto-Vision's tiny camera can get into dark hidden spaces and simultaneously illuminate the area while providing full color digital video. 
In air duct cleaning, not only can the Roto-Vision be used for inspection before and after cleaning, it can be used as an active monitoring system during cleaning. The Roto-Vision digital camera can be attached directly to the Rotobrush hose up to two (2) feet behind the brush and nozzle. As the Rotobrush cleans, the Roto-Vision system will display an active picture of the entire cleaning process.
