WORKING WITH THE MOTION TAB
The DVR5100 Remote Client allows you to set up to three motion detection zones per camera. These zones may be any size and shape, and they
may be set to high or low sensitivity to motion. Motion settings may be used to trigger alarms of varying severity (minor, normal, major, or critical)
that can be included in recording schedules. From the video pane, you can show or hide detected motion. You can also search for motion events
using Quick or Enhanced Search. Motion must be enabled before the Motion tab is displayed.

Understanding the Motion Threshold
The DVR5100 Remote Client allows you to specify the motion threshold value in number of blocks. Table I describes the terminology and options
for setting the sensitivity and threshold values.
Table I. Motion Sensitivity and Threshold
Option Description
Sensitivity Determines how sensitive each individual block is to motion detected within it (1–100; default is 50).
Threshold
Determines the number of blocks or percentage of blocks that must detect motion to trigger an alarm. The motion zone
can be up to 1350 blocks.
• Threshold Percent: Allows you to specify the threshold level in percentage. By default, this value is set to 20
percent. The Threshold Percent range is automatically adjusted between 2–100 percent, depending on the number
of blocks used to define the motion zone.
• Threshold Blocks: Allows you to specify the threshold level in number of blocks. By default, the minimum number
of blocks is 2.
Activate zone Determines whether alarms will be triggered by motion in the defined zone. By default, this setting is not enabled.
