Motion Detection Parameters
A zone pattern grid overlays the video image when setting up motion detection. Each of the blocks on this grid can be independently turned on or off. This creates inactive areas where motion detection is not needed, and active areas where one of up to 8 separate sets of motion detection (A-H) are assigned according to the following settings:

Tracking settings reduce false alarms from transient or unwanted motion. 
This prevents false alarms from, for example, lightning or birds flying through the scene.

Size settings allow for alarming based on a minimum required object size.
This allows the unit to reliably distinguish between, for example, people and animals.

Sensitivity settings compensate for low-light or low-contrast situations.
This assures reliable operation in a variety of lighting conditions.

Motionless detection criteria are set up as above.
For Direction Detection, up to 8 zones may be paired (A'B, C'D, E'F, G'H).
 

Viewing Modes
The DS-1PL offers several viewing modes that reduce viewing fatigue and facilitate the assessment of on-screen information:

Trace Mode outlines moving objects with a "sparkle effect," and is available in three variations:
Normal Trace Mode; Trace/Memory, which allows trace to accumulate on-screen; and Trace/Flash, which shows the trace as a flashing overlay, allowing viewing of the underlying scene.

Blackout Mode leaves screen black, except during alarms, thus reducing viewing fatigue.

Blackout and Trace Modes can be combined, to show only a black background overlayed with the trace caused by movement in the scene.
 

Motion Detection Set-Up
Special on-screen indicators help determine optimal motion detection settings for each application:

Pixel Count shows the number of pixels being "violated"-that is, how much motion is being detected. 

This number changeswith the activity in the video scene, thus allowing the operator to see what kinds of activity does and does not cause an alarm.

Peak Pixel Count displays only the most recent maximum number of pixels violated in the video scene, and changes only when a new maximum is reached. This feature allows the operator to determine threshold levels for motion detection.

Alarm Count by Zone displays a continuous update of the number of alarms for each active zone.
