2.2 Snapshot
If the service linkage of the video source (see Section
5.1.3
) includes snapshot, when service
linkage takes place, automatic snapshot will be taken. The snapshot pictures will be saved in
the recording partition. For the same alarm, if multiple video sources (that is, cameras) are set,
snapshot will be taken by the principle of “first occupy and first snapshot”. Every time when a
snapshot is taken, the cameras will compete for the snapshot right at an interval of five seconds.
