I wont need a security camera nor a motion sensor to keep tracks of the halls. I want it to be a platform where some people will be given access to the site where as a class delegate enters a hall with a lecturer, he logs in to the site and tick a certain space in the platform indicating the hall is occupied and as so as he leaves the hall he logs in again and undo what he previously did making the fall free. My problem right now is developing the website or the mobile app.
