[Number of] seconds pre/post recordings on event:
Available only when the option
Conditional
is
selected, i.e. when video received from the camera should be stored in the database on certain
conditions only.
You are able to store recordings from periods preceding and following detected motion and/or
specified events. Using such a pre/post buffer can be advantageous: If, for example, you have
defined that video should be stored when a door is opened, being able to see what happened
immediately prior to the door being opened may be important.
Specify the number of seconds for which you want to store video from before and after the storage
conditions are met.
Example: You have specified that video should be stored conditionally on event, with a start event
called
Door Opened
and a stop event called
Door Closed
. With a pre/post buffer of three seconds,
video will be stored from three seconds before
Door Opened
occurs to three seconds after
Door
Closed
occurs.
Note:
Pre/post recording periods cannot be displayed in the timelines of NetGuard-EVS's timeline
browser. The fact that these periods cannot be displayed in the timeline browser's timelines does
not affect recording.
