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.

None, Event, Alarm number (tied to camera number)
1 (least) to 9 (most)
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.
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).
Press the enter button to move into edit mode. Use the arrow buttons to select or deselect the
areas on the gird to set for motion detection. Press the enter button to cycle through the
selection cursors:
• White outline: Use to position cursor for selection or deselection of a previously selected
area
• Blue: Selects areas on the grid for motion detection
• Red: Cursor changes to red when parameter thresholds are achieved
• Green: Area to be monitored
Press the menu button to go to the commands in the edit window. Select from:
