Image snapshots in a http-enabled folder will allow for low-bandwidth viewing and archiving. Should be configurable to:
1) take a snapshot (per-camera) at a regular interval measured to at least 1/10th of a second.
2) take a set of N images on motion detection from T1 seconds prior to the event (requires image buffer) to T2 seconds after the buffer. Eg: take a snapshot 10 times per second starting 10 seconds before motion detection and stopping 10 seconds after motion detection.
