Adding comments in different surveillance modes

In Archive and Archive Analysis modes, comments can be added both for specific frames and for intervals of time.
To add a comment for an interval, select an interval on the timeline, place the timeline indicator either inside the interval or at one border of it, and click the button.

In Alarm Management mode, operators can be required to give comments after classifying an event (see 알람 처리 구성) or comments can be left in free form, before event classification, by clicking the button. The comment applies to the entire duration of the alarm. You can add a comment in real time only if archive recording is enabled.
