I want to hook up an inexpensive ceiling cam for a very small office. It should record for a specified time frame each time the door opens and make those videos immediately available to an online location that I specify.
I want to avoid any monthly fees for something proprietary and would prefer open-source free software. I might even try to start small with my Logitech cam pro 9000.
What hardware and software do I need to tie that to the door opening?
