MOTION DETECTION
The
SW-D7000U
offers motion detection capabilities, including built-in Activity Detection. Activity
detection is used to adjust the rate at which cameras are recorded and can activate an output relay to
cause automatic external actions such as speed change on the VCR, or floodlights, or audio
announcements and so on.
The difference between Intrusion detection and Activity detection:
When digital video motion detection is used, it is important to know the difference between simple
activity detection and intrusion detection.
Activity detection:
Activity detection simply looks for changes in the luminance in various selected areas of the screen,
and if changes are above a set threshold (sensitivity) then the activity detector interprets that to be
activity. Typically, activity detection is used to detect activity in crowded areas, where activity is not
the result of intruders and where human traffic is normal and expected.
Intrusion detection:
Intrusion detection looks for real movement in the scene, and raises an alarm if it is found. It is used
to monitor areas where no human traffic is allowed or expected, and so when movement is found it
will be likely that it was caused by an intruder, and so an alarm should result. It is hence important
that intrusion detectors do not cause false alarms, resulting from light changes, camera vibration or
random reflections of light in the scene. An ability to reduce false motion alarms, in areas where no
motion is expected, is the key difference between intrusion detection and activity detection.
Upon selection of the MOTION DETECTION menu item, the following pull-down sub-menu appears:
Enable / Disable Detection
Setup Active Zones
Indicate Detection
Activity / Intrusion
Setup Parameters

ENABLE / DISABLE DETECTION
Each camera has the MOTION DETECTION function disabled when the unit is first powered up
(Factory default). The first setup item, which should be done by a programmer, is to enable the
cameras.
Select the ENABLE/DISABLE DETECTION section of the MOTION DETECTION sub-menu and the
following menu appears:
