We have many analog cameras with local DVRs in multiple buildings.
We are looking for an open source solution, to convert analog cameras to digital, have local storage and backup (in near real-time) to a remote location.
Looking for a how-to solution and equipment needed to accomplish this:
Buy product x to convert the cameras to digital,
use a Computer with software Y for the local storage - software Y will also send video to a remote location for backup.
No custom software/hardware.
