This is a really good example of why it's cool to have cameras around the place.

Agreed. It needs to be really obvious which areas of the space are
being recorded at any given time.

I think having all the cameras recording at a time could and should be
used sparingly with a notice being posted that an event is happening
where that would be taking place.
I think it would be really neat for someone to be able to tell the
server to record a video or an image at a (tunable) frequency (like
you have for the timelapse) to record builds. That camera would have
it's corresponding lights on the info board illuminate so people know
that if they go within its view they will be recorded.

While I'm the one who originally proposed this, on reflection I don't
think it would actually be a good idea, at least not a 'kill all the
cameras' button. If someone had been working on a time lapse of a
build they'd be pretty miffed if someone cut it off, especially if
that concerned person never went in to the field of view of that
camera. As long as, at any time outside of the global "we're recording
everything", there is somewhere people can work and hang out without
being recorded I think it'll be fine.

I'd make the recordings from when the space is closed available in a
general share on Morphia and then when a user/member requests a
video/interval they should go in their home directory (under some user
configurable location [yes, I'm volunteering to do that bit]).
Recording all cameras for the whole time the space is closed isn't
feasible, we just don't have that much disk space. We can how ever use
packages like Motion to trigger recordings when there's movement.
Telling Motion to stop monitoring the cameras is an exercise in bike
shedding so let's build that bridge when we need it.

The way that PS:one is anonymising the data is good.
With the 3d from 2d tech you've been playing with (or just some
birds-eye-view placements) I think it would be possible to generate a
heat map of the space which would be utterly cool and something I'd be
interested in helping with.
