The only problem with that is that the off the shelf web cam does not write back to the Database for the nurse call system to say that someone without a badge was in the room, and doesn't alert anyone. Also I an not wanting to have a pc in every room with the camera.
Well, there are off-the-shelf solutions that certainly can do any of that, except that I don't see any way for any of these solutions to know whether there was a badge in the room. How do you envisage that part working?
