Does keyframe interval or fps affect motion detection

I have my cameras at a low frame rate (4fps). Does frame rate have any impact on motion detection, specifically is there any need for a faster rate with respect to motion detection?

Also, I have one camera where I can affect keyframe rate. It defaults to 12 (for 4fps). The other cameras do not appear to let me change and are at 8 (for 4 fps). Does motion detection occur on every frame, or only keyframe (I ask because one other product only did detection on keyframes)? This in turn feeds into the fps question, as if keyframes are important the only way with most of my cameras I can increase the keyframe rate is increase the frame rate.
