Chapter 7 Record Setup
7.2.2 Encode FPS (Frames Per Second)
Frame rate is the amount of individual images that are put together to make one second of video or frames per second (FPS). In CCTV cameras you can adjust
the number of images that are used to make up a second of video, less images used equals less storage used.
There is a trade off in video quality when reducing the frame rate, keeping in mind that 24fps is the standard for cinema so video around this frame rate will
look natural, anything below about 15fps will start to look a little jerky and unnatural. However, the purpose of CCTV is not to make cinematic masterpieces, it is
to record events to check for details later on. So long as the frame rate is high enough to capture images to be able to identify an intruder the smoothness of
the video doesn't really matter.
FPS: To adjust your frame rate select the value you want from the FPS drop down menu.
The menu will automatically update the rates based on the camera being used and the
resolution selected; generally the lower the resolution the higher the available frame rate
will be.
You may notice in the machine specifications there is a difference between the maximum
FPS of your recorder and your camera, this is because your recorder is designed to work
with a higher rate in case you add a camera that has the ability to work at a higher rate.
Reducing frame rate is one of the biggest savings you can make on storage space and is
definitely one of the first things you should adjust when trying to minimise bandwidth. You
will need to use a bit of trial and error to determine what is the optimum setting for your
situation.
