Bull, don't mean to rain on your parade, but.....the Denta-Cam would most likely be considered a medical devise and will require some type of FDA approval which can take a lot of time, money, and effort. Although it is considerably easier when it is a product similar to existing FDA approved products, it still a bureaucratic nightmare. Lots of stuff to prove, like how do you sterilize the camera and prevent contagous agents like HIV from being transferred from one patient to another. A big concern in dentistry. And the product liability costs are outrageously high. Just the direction inserts will be a *****, nothing as simple as the instruction sheets they have with the SecureView or marine cameras.
Doubt if they have even explored this yet. I use to work in the medical business and it is a whole different world. I would almost bet this idea will end up on the backburner until they have more fully tapped much easier markets for their product, like home and small business security. JMHO
