When motion is detected, the signals are displayed in the Motion window shown below.
Detailed settings for motion detection are as follows:

Sampling pixel interval [1-10] – Select a number from 1-10. The default value is 1. If the
value is set as 3, within the detection region, the system will take one sampling pixel for
every 3 pixels by each row and each column (see the figure below).

Detection level [1-100] – Select a number from 1-100. The default level is 40. This sets
detection level for each sampling pixel; the smaller the value, the more sensitive it is.

Sensitivity level [1-100] – Select a number from 1-100. The default level is 80, which means if
20% or more sampling pixels are detected differently, the system will detect motion. The
bigger the value, the more sensitive it is. When the value is bigger, the red horizontal line in
the motion indication window will be lowered accordingly.

Time interval (sec) [0-7200] – Select a number from 0-7200 (seconds). The default interval is
10. The value is the interval between each detected motion.
Triggered Action
The Administrator can specify alarm actions to be taken when motion is detected. See Figure 57:
Motion Detection Screen. The options are listed as follows:

Enable alarm output – Check this box and select the predefined type of alarm output (low or
high) to enable alarm relay when tampering is detected.

Record stream to sd card – Select this box to store the motion detection alarm recording in a
microSD/SDHC card when tampering is detected. Enter the number of seconds for the pre-
trigger buffer. Select the first radial button to upload for a specified length of time and enter
the number of seconds. Alternatively, select the second radial button to upload during the
active trigger. See Figure 53: Application – Record Stream to SD Card.
Note:
Make sure the local recording (with microSD/SDHC card) is activated so that this
function can be implemented. See

Send Message by FTP/E-Mail – Select whether to send an alarm message by FTP and/or
e-mail when motion is detected.
