Figure 74. The motion detection parameters setup menu
Navigate in this menu using the arrow keys to select the field and change the parameters.
Activity Vs. Intrusion
Activity detection is a simple type of motion detection having only a sensitivity setting and a relay output.
Intrusion detection is a more sophisticated type of motion detection, with additional features such as false
alarm rejection levels, minimum target size, and an alarm output.
Activity Detection Setup
If
Activity
is selected in
Motion Detection Type
field, the following parameters are enabled:
Relay Output:
The unit may be configured to activate a relay output when motion detection is present. Select
either
1
,
2
,
1+2
(both relays), or
none
.
Link to Event:
Selecting
Yes
in this menu will activate the event record speed when activity detection is
present.
Intrusion Detection Setup
If
Intrusion
is selected in
Motion Detection Type
field, the following parameters are enabled:
Sensitivity:
Use the arrow buttons to change the motion detection sensitivity, 10 being the most sensitive.
Note:
The 10 setting may be too sensitive in most cases. Even changes that are not perceptible by the human eye may trigger
a motion indication.
Rejection:
Configure the unit's false alarm rejection feature by selecting
Low
,
Medium
, or
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).
Target Size:
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.
