Where is the remote webcam add-in?
A few basic features would be helpful:
1: Support up to at least 4 cameras.
2: Allow me to reconfigure the streaming video port.
3: Maybe add in a 'motion detection' option on a per-camera basis like most CCTV systems to fire off alerts or capture camera snapshots to a folder on the server.
4: Maybe even allow for some audio?
I already have multiple USB Cameras, and long ago used a 3rd party app to do this (X10). It just makes sense to me to have an add-in for this where most people already have cameras, or can pick them up for $10 or less.
It would also extend the Essentials Server idea to also have CCTV features as an add-in, rather than have to keep them separate.
