Understanding the Threshold Percent

The Threshold Percent allows you to specify the number of blocks in a motion zone that must detect motion before a motion event can be initiated.

Scenario 1: Motion Zone = 100 Blocks

For example, if the motion zone has 100 blocks (maximum setting), you can set the Threshold Percent option to 2 (minimum setting). In this case, the number of detection blocks in the motion zone can be as few as 2 (refer to Figure 80). You can adjust the threshold blocks from 2–100 blocks. These values are derived as follows:

Number of Detection Blocks = (Zone Blocks x n%)/100 or 100 x 2/100 = 2

Figure 80. Motion Zone and Threshold Percent: Example 1

NOTE: Threshold Blocks cannot be set to a value less than 2. If you attempt to do so, the remote client will automatically readjust the value to 2.

Scenario 2: Motion Zone = 50 Blocks

If the motion zone has 50 blocks and you attempt to set the Threshold Percent option to 2 percent, the remote client automatically readjusts this value to 4 percent (refer to Figure 81 on page 71).

Number of Detection Blocks = (Zone Blocks x n%)/100 or 50 x 4/100 = 2

Figure 81. Motion Zone and Threshold Percent: Example 2

Scenario 3: Small Motion Region = 16 Blocks; Large Motion Region = 56 Blocks

If multiple regions are defined in a motion zone, the DVR5100 Remote Client:

•Adds the blocks from each region to arrive at total blocks for the motion zone.

•Bases the threshold calculation on the total blocks.

For example, in Figure 82 on page 72, there are two regions: a larger region (56 blocks) and a smaller region (16 blocks) totaling 72 total blocks assigned to the motion zone. The Threshold Percent is set to 28. In this case, 20 blocks (72 blocks x 28% = 20) must detect motion before a motion event is triggered.
