Continuous archiving is the automatic process of sending video clips from selected cameras to a secondary location for storage. This practice is unique because it happens free from user intervention; instead of administrators choosing which clips to archive, the system itself sends footage to a storage facility. This means that recent footage that might have caught a reported event, including a triggered alarm, still exists somewhere and can be retrieved so that you get the chance to review it. It’s an added layer of security from your CCTV cameras.
This is a process that is independent from video event archiving, which is when users select certain clips of events to save in storage. However, it can happen in tandem with event archiving, meaning that different shots of the same event could end up being saved, even if completely by accident. When using CCTV cameras, continuous archiving is just another method of ensuring system safety.
