I worked at a medical clinic that was looking to do something similar. When the COO found out I was a Raspberry PI hobbyist, he approached me to find out if his plan was possible. What he wanted to do was to put IR sensors in all the medical exam rooms, so he could determine usage, without impacting patient privacy. This was technically quite easy to do, but not something that went forward, mostly due to too many other projects. This same COO later became the head of a private school...
