Video (properties)

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

When you configure video and recording for specific cameras, you can use either the MJPEG video format or the MPEG video format. Depending on which of the two options you choose, you can set different options for your camera.

MJPEG video format

With MJPEG, you can define frame rates for regular as well as speedup modes. If the camera offers dual stream, you can also enable this. Note that there are three places where you can set frame rate:

Live Frame Rate - used for the regular recording stream
Live Frame Rate - used when speeding up recordings in connection with motion detection or similar functionality.
FPS (frames per second) - used for the additional stream used for live viewing.

Regular frame rate mode

Frame Rate

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

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.

Recording Frame Rate

Required average frame rate for recorded video from the camera. Select the number of frames, then select the time unit interval (second, minute or hour). The frame rate must be higher than the frame rate specified under normal mode.

Speedup frame rate mode

Enable speedup frame rate	The speedup feature lets you use a higher than normal frame rate if motion is detected and/or an event occurs. When you enable speedup, further columns for specifying speedup details become available.
Frame Rate	Speedup frame rate for viewing video from the camera. Select the number of frames, then select the time unit interval (second, minute or hour). The frame rate must be higher than the frame rate specified under normal mode.
On motion	Select this check box to use the speedup frame rates when motion is detected. The camera will return to the normal frame rates two seconds after the last motion is detected.
On event	Select this check box to use the speedup frame rates when an event occurs and until another event occurs. Use of speedup on event requires that events have been defined, and that you select start and stop events in the neighboring lists.
Start Event	Select the relevant start event. The camera begins using the speedup frame rates when the start event occurs.
Stop Event	Select the relevant stop event. The camera returns to the normal frame rates when the stop event occurs.
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). The frame rate must be higher than the frame rate specified under normal mode. 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.
Recording Frame Rate	Required average frame rate for recorded video from the camera. Select the number of frames, then select the time unit interval (second, minute or hour). The frame rate must be higher than the frame rate specified under normal mode.

Speedup does not necessarily have to be based on motion- or events, you can also use scheduling to configure speedup based on particular periods of time. If you prefer such time-based speedup, you should still enable the use of speedup by selecting the Enable speedup check box.

Dual stream

Enable dedicated live stream	This additional stream feature lets you use the alternative stream of the camera. It enables two independent streams to the recording server—a stream for live viewing and another stream for recording purposes, with different resolution, encoding, and frame rate.
Stream	Select the type of the live stream. Stream settings for viewing live video and for recording video may very well be different in order to get the best result.
Resolution	Select the resolution of the camera.
FPS	Select the camera's live frame rate per second (FPS)

MPEG video format

Frame rate

Frame rate per second	Frame rate for viewing live and recorded video from the camera. Select number of frames per second.
Record keyframes only	Key frames stored at specified intervals record the entire view of the camera, whereas the following frames record only pixels that change. This helps greatly reducing the size of MPEG files. Select the check box if you only want to record keyframes. Note that you can specify exceptions if motion is detected or events occur.
Record all frames on motion	Allows you to make exceptions if you have selected to record keyframes only. Select this check box to record all frames when motion is detected. Two seconds after the last motion is detected, the camera will return to recording keyframes only.
Record all frames on event	Allows you to make exceptions if you have selected to record keyframes only. Select this check box to record all frames when an event occurs and until another event occurs. Use of this feature requires that events have been defined, and that you select start and stop events in the neighboring lists.
Start Event	Use when recording on Event or Motion Detection and Event. Select the relevant start event. The camera begins recording all frames when the start event occurs.
Stop Event	Select the relevant stop event. The camera only records keyframes when the stop event occurs.

Dual stream

Enable dedicated live stream	This additional stream feature lets you use the alternative stream of the camera. It enables two independent streams to the recording server—a stream for live viewing and another stream for recording purposes, with different resolution, encoding, and frame rate.
Stream	Select the type of the live stream. Stream settings for viewing live video and for recording video may very well be different in order to get the best result.
Resolution	Select the resolution of the camera.
FPS	Select the camera's live frame rate per second (FPS)
