These are WIFI enabled cameras with pan/tilt and 2 way audio (at least for windows). They have an integrated web interface and both an administration mode and a user mode. They can be programmed to run a pattern and only record when there is motion. The output can be directed to a server of your choosing or to the cloud.
I am thinking these could serve a dual purpose. The user mode could be used as Tele-presence devices. The device logs who connects to it and that can be sent to a server too. We can scan the logs for who is connected and put the name up on a display at the front of the room.
My next idea for added security? Dogs and Bazookas!
