In Nurdspace we use Constatus for recording (on demand - when the motion detectors detect motion while the space is closed) video from several cameras. scrollert is the main server for this. The rpi at the bar (the one managing that ticker) is a slave-system.
If you like more info about it, ping flok on irc in #nurds. If you like you can have a demo on friday or saturday evening in Nurdspace (note: not currently as we're closed for visitors due to corona).
