Set Sensor Event Recording
●
Priorities of Motion Detection and Sensor Event Recordings
You can specify events priorities for the Motion Detection and Sensor Event recordings,
and if the events occur simultaneously, the recording with the higher priority is performed
first.
When using the Motion Detection and Sensor Event recordings together and motion
detection and sensor input occur simultaneously, the Sensor Event recording takes
precedence.
If two events with the same priority occur, the earlier event takes precedence. When the
earlier event terminates and the later event still remains, the later event will be handled.
