Startup Idea: Biometric and Surveillance Tech for Night-time Daycare

Startup idea to develop a cost-effective technology for a small, night shift daycare center. The solution would track children's breathing rhythm, heart rate, movement, and provide automated audio and video alerts when children enter restricted areas.

I run a small daycare center that cater to parents that work night/3rd shift. Ideally, the children I watch would sleep through most of the night, but it seems they are as mush as night owls as their parents! I have my business set up where the sleep area is farthest away from the eating/cooking/lounge section for the adults; and although my staff is vigilant, at least twice a week a child will slip away to play in areas they shouldn't.

I dream of a technology that can track the breathing rhythm, heart rate, and movement of a body. Also video and audio that is automated so if someone goes past a certain area we are instantly alerted. A bonus would be affordability of this technology.
