Recording (properties)

The term recording means saving video and, if applicable, audio from a camera in the camera's database on the surveillance system server.

Video/audio is often saved only when there is a reason to do so, for example as long as motion is detected, when an event occurs and until another event occurs, or within a certain period of time.

When you configure video and recording for specific cameras, recording properties include:

Always

Record whenever the camera is enabled and scheduled to be online. The latter option allows for time-based recording.

Never

Never record. Live video is shown, but users cannot play back video from the camera because no video is kept in the database.

Conditionally

Record when certain conditions are met. When you select this option, specify required conditions (see the following) which enables you to store recordings from periods preceding and following detected motion and/or specified events.

Example: If 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 also be important. Say 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 three seconds of pre-recording, video is recorded from three seconds before Door Opened occurs and until Door Closed occurs.

Built-in motion detection

Select this check box to record video in which motion is detected. Unless post-recording (see the following) is used, recording will stop immediately after the last motion is detected.

On event

Select this check box to record video when an event occurs and until another event occurs. Use of recording on event requires that events have been defined, and that you select start and stop events in the neighboring lists.

Use the Configure events list located below the other fields to define events that suit your needs.

Start Event

Select the relevant start event. Recording will begin when the start event occurs, or earlier if you use pre-recording. See the following.

Stop Event

Select the relevant stop event. Recording will end when the stop event occurs, or later if you use post-recording. See the following.

Enable pre-recording

Available only when the option Conditional is selected.

Specify the number of seconds for which you want to record video from before recording start conditions (that is motion or start event) are met.

Enable post-recording

Available only when the option Conditional is selected.

Specify the number of seconds for which you want to record video after recording stop conditions (that is motion end or stop event) are met.

Note that manual recording may be enabled. With manual recording, users of XProtect Smart Client with the necessary rights can manually start recording if they see something of interest while viewing live video from a camera that is not already recording. If enabled, manual recording can take place even if recording for individual cameras is set to Never or Conditionally.
