By default, video is recorded to the archive with the same frame rate as the video capture card digitizes it. Thus, to reduce the archive size, you can configure the frame rate of this parameter.
Note
To change the recording frame rate, do the following:
Specify the recording frame rate value in the Recording frame rate field. The value mustn't exceed the digitization frame rate value. The value set for the Recording frame rate parameter allows calculating the interval (msec) in which a frame must be captured for archive recording. You can calculate according to the formula:
Time interval = 1000 / Value in the Recording frame rate field
Note
Setting the video frame rate is complete.
