3. Select a camera from the Camera Selection drop-down list, and configure these settings:
 Mask Region: If necessary, mask off the area on the camera view where any scene change
will be ignored.
 Sensitivity: Adjusts detection sensitivity. The higher the value, the more sensitive the system
is for changes in the camera view.
 Tolerance Time of Alarm: Sets the duration of scene change before an alarm condition is
activated. Move the slider or type a value (in second) in the blank.
 Automatically Disable Alarm: Stops all types of triggered alerts, including sound alarm,
flashing boxes and output module after the specified duration. Disabling the alerts will not
disable alert settings and the detection in progress.
 Skip Instant Light Change: Ignores sudden illumination changes to minimize false alarms.
For example, light switches can cause illumination changes suddenly. With the option
selected, the system will ignore significant illumination changes without triggering the alarm
and continue monitoring. See the Note below for possible risk.
 Invoke Alarm: Enables the computer alarm when the scene change is detected. Click the […]
button next to the option to assign a .wav sound file.
 Output Module: Activates the output device when the scene change is detected. Select this
option and use the drop-down list to assign an installed output module and a pin number.
 Never Recycle: Prevents the system from recycling the event files of scene change when the
recycle threshold is reached.
4. You can click Test to test your settings. If the scene change cannot be detected, increase
Sensitivity value to increase system sensitivity to changes in the camera view.
5. Click OK to apply the settings.
6. Start monitoring to run the application.
When a scene change is detected in the camera view for the specified time, its location will be
highlighted in live video, the selected alarm or output will be activated, and the event will be recorded
as Advanced Scene Change in System Log for later retrieval.
