Ghost hunting is apparently a popular hobby, with media and cable programs galore.
And ghost hunters love CCTV equipment, and not just the cheap stuff either, FLIR cameras are all the rage these days. Many stores sell esoteric and expensive equipment (EMF detectors, full spectrum cameras, etc) with dubious value for the consumer.
And then they have their own gear too. Take a look at this 'novel' 360 infrared puck light.
Maybe it was originally designed to snap into the middle of an icRealtime 720 , but stand alone it will set you back $130.
So, assuming you don't believe that spectrers can be captured by cctv, would you sell, install and consult on a system that you don't believe could ever work for what it's intended to do?
Why or why not?
