Motion Detection
Use this menu to set up the various parameters associated with motion detection such as the trigger, sensitivity,
target size, rejection threshold, and where on the video to monitor for motion.

Menu setting Options
Trigger None, Event, Alarm 1-16, IP Alarm 1-4
Indicator Check to enable/disable the displaying of the M indicator.
Sensitivity 1 (least) to 9 (most)
Target size 0-256. This setting is the minimum number of zones (from the 16 x 16 grid) that must be
activated simultaneously before it is considered to be valid motion.
Rejection None, low, medium, high. These settings are based on the number of simultaneously triggered
zones and the persistence of motion in a scene. The Low setting is the most sensitive to motion.
The Medium setting will filter out most false alarm situations due to sudden luminance changes
over the whole scene (clouds passing over). The High setting will filter out sudden luminance
changes as well as spurious motion events that do not persist for a number of frames (a bird
flying past the lens).
