We just got a new office; and for security purposes, we'd like to have a bunch of webcams, with data streamed to a centralized server (for motion detection / logging).
"Privacy" is not a problem as it's a small company and all the founders are okay with it.
What are the best open source tools for this? We'd like the backend to be linux, and for the actual cameras, just get a bunch of cheap cameras (that can hopefully stream over wireless or network).
We liked it so much better than the multi-kilo-buck commercial offerings that we use it everywhere, even where we had expensive proprietary setups before.
