7.5.4. About the Alarm Input Mode
The Alarm Input mode for Alarm Recording can be set to "EDGE" or "LEVEL."
Each input mode operates as follows:
[Recording period when input mode is set to "EDGE"]
Performs continuous recording during Pre-alarm Recording and Alarm Recording Periods.
[Recording period when input mode is set to "LEVEL"]
Provides continuous recording during periods of time of Pre-alarm Recording, alarm activation, and Post-
alarm Recording.
Note
Pre-alarm recording is operated by the Alarm Recording Setting. It does not operate even if an alarm is
activated during General Recording or Internal Timer Recording since they are operated by their own settings.
