Figure 26. Activity Detection Mask
Activity detection continually monitors selected camera inputs for activity. When activity is
detected, the multiplexer increases the frequency with which those cameras are shown and
recorded. Activity detection is most effective when only a few cameras are showing activity.
As the number of cameras with activity increases, the slower the frequency at which they
can be shown and recorded. If all 16 cameras show activity, there will be virtually no
increase.
