Configure storage: Live and recording settings - H.264/MPEG4 cameras

Available functionality depends on the system you are using. See the Product comparison chart for more information.

This wizard page only appears if one or more of your cameras use the H.264/MPEG4 video format.

Specify which frame rate to use for each camera, and whether to record all frames or keyframes only. You can also select pre- and post-recording, allowing you to store recordings from periods preceding and following detected motion and/or specified events.

Note that all of the properties can also be specified individually for each camera.

Live Frame Rate

The required average frame rate for live video from the camera. Select the number of frames, then select the time unit interval (second, minute or hour).

If the camera supports dual stream and you have enabled dual stream, the Live Frame Rate column is read-only with the value Dual streaming. You cannot change this.

Record on

Select under which conditions video from the camera should be recorded:

  • 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.
  • Event: Select this to record video when motion is detected. Unless you add post-recording, recording stops immediately after the last motion is detected.

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

  • Motion Detection and Event: Select this to record video in which motion is detected, or when an event occurs and until another event occurs. Remember to select start and stop events in the neighboring columns.

Pre-recording

You can store recordings from periods preceding detected motion and/or start events. Select check box to enable this feature. Specify the required number of seconds in the neighboring column.

Seconds [of pre-recording]

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. Usually, only some seconds of pre-recording is required, but you can specify up to 65535 seconds of pre-recording, corresponding to 18 hours, 12 minutes and 15 seconds. However, if specifying a very long pre-recording time, you can potentially run into a scenario where your pre-recording time spans scheduled or unscheduled archiving times. That can be problematic since pre-recording does not work well during archiving.

Post-recording

You can store recordings from periods following detected motion and/or stop events. Select check box to enable this feature. Specify the required number of seconds in the neighboring column.

Seconds [of post-recording]

Specify the number of seconds for which you want to record video from after recording stop conditions (that is motion or stop event) are met. Usually, only some seconds of post-recording is required, but you can specify up to 65535 seconds of post-recording, corresponding to 18 hours, 12 minutes and 15 seconds. However, if specifying a very long post-recording time, you can potentially run into a scenario where your post-recording time spans scheduled or unscheduled archiving times. That can be problematic since post-recording does not work well during archiving.

Keyframe Only

Select Keyframe only if you want motion detection to take place only on keyframes of the video stream to reduce the system resources used on motion detection.

The template can help you configure similar properties quickly. For example, if you have 20 cameras and you want a particular frame rate on all of them, you can enter it once in the template, and then apply the template to the 20 cameras.
