The Digital Input signal triggers can be congured as follows:
1. Traditional Recording: can be triggered when the DI enters the Trigger State or the Normal
State. If thus configured, the recording task will end when the post-event recording time is
reached.
2. The recording starts when DI is triggered, and will end when the DI signal returns to Normal.
3. The recording starts when DI is Normal, and will end when the DI signal returns to Triggered.
An example for the conguration can be: the recording starts when a door is opened (DI triggered),
and the recording stops when the door is closed (DI returns to normal).
When connected, a camera's Digital input signal is automatically detected as pulled-high or pulled-low.
Users should then designate the current state as Normal or Trigger. The conguration page is found in
Conguration > Application > Digital Input on a web console.
