Motion indicator
To prevent false alarms, a threshold can be applied to the motion signal. This
allows effects such as the background noise from the camera itself to be filtered
out.
The blue line in the illustration represents the alarm threshold. Any value above
this level will trigger an alarm. The parts of the motion signal line which will cause
an alarm are shown in red. The alarm threshold can be set higher or lower to suit
your needs.
– Observe the amplitude of the displayed movement signal over a longer period
of time under all the lighting conditions that may be encountered.
– Move the pointer over the blue line.
– Press the left mouse button in and drag the line to the desired level.
Motion tracking
In some situations you may want an alarm triggered only if movement takes place
in a particular direction. In such cases, enable motion detection and select the
direction of movement required to trigger an alarm.
– Select On to enable the motion tracking feature of the video sensor.
Tracker
The Tracker field shows an arrow indicating the current motion vector in the
video image. The checkboxes at the corners of the field are used to select the
directions to monitor. For example, if all movements toward the left and up are to
trigger an alarm, mark the top left corner. If all movement to the left is to trigger
an alarm, mark the upper left and the lower left checkboxes.
– Observe the movement in the video image indicated by the arrow over a longer
period of time at all the relevant light levels.
– Mark the checkboxes to activate the corresponding directional components for
monitoring.
