Frame rate, aka FPS, (Frames per Second)

What does frame rate mean?
Frame rate refers to the number of individual frames that make up one second of recorded video. So, how many frames per second (FPS) do you need for your CCTV camera to capture the best footage possible?

Why does frame rate matter?
The greater the FPS, the smoother the video recording will be. For example, if your frame rate was 1 FPS and you were trying to capture footage of an individual running, you will only be able to capture one frame containing the individual as he/she would have cleared the field of vision (FOV) between frames.
