■ Pre-alarm recording
When pre-alarm recording has been set beforehand, the same images will be recorded normally in the normal recording area and also in the alarm recording area. The normal recording images will be recorded in this way for the length of time specified by the DURATION setting, so that the images recorded before the alarm occurred can also be seen when the alarm recording is played back.

2 The most recent images will be recorded automatically for the specified duration, and they will be updated by being overwritten.
