Note
• A combination of continuous and event-based recording from a camera can
be achieved using the relationship between Frames Per Second (FPS) and
Group Of Pictures (GOP).
• FPS is a measure of the images every second from the camera, while GOP
determines how frames are sequenced.
• Every GOP starts with an I-frame (full image) and is followed by smaller
images which are relative to the images preceding it. So, for a GOP of 5 there
will be one I-frame for every 5 frames.
The following figure shows an example of three seconds of video at 5 FPS and 5 GOP.
Figure a-2 I-frame Example
The NVR record Quality Settings for Continuous (background) and Event recording can be
used to achieve different level of FPS by selecting one of the following options.
• Same as Live : Every frame is recorded (5 FPS in the example)
• Every I-frame : Every I-frame is recorded (1 FPS in the example)
• Every Second Iframe : Every second I-frame is recorded (1 frame every 2 seconds in the
example)
• Every Third Iframe : Every third I-frame is recorded (1 frame every 3 seconds in the
example)
Note:
For more detailed information on the relationship between FPS and GOP and
example settings to achieve different frame rates, refer to the
