I know this is old, but I bought one of those cheap 16 foot camera and use my laptop and was able to see the awesome work by Dutchman on my single AC< I wish I had bought two, I live in Tucson and that thing bakes in the summer sitting up on top, I also made a deflector for it since closing it off and shoving all that air through junky built duct work ( With the camera it is evident Dutchman did not seal the ducts to the framework,, and I get bleed through all over,, also found behind the TV they had punctured the duct with a vent pipe and with wires from TV<<
