Record keyframes only
Keyframes 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 (see "Overview of events and output" on page
104) 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 required start event. The camera will begin recording all
frames when the start event occurs.
Stop Event
Select required stop event. The camera will again only recording
keyframes when the stop event occurs.

This feature is only available on cameras supporting dual stream.
Name Description
Enable dedicated live stream

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)
If the camera uses the 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.
