2.6.5 Configure the SCD settings [SCD area]
Click the [SCD area] tab on the “Alarm” page. (→For menu display and how to operate, refer to 2.2.1 How to display the setup menu, 2.2.2 How to operate the setup menu)
By configuring SCD (scene change detection) setting, it is possible to issue an alarm when a camera is covered with something or the camera direction is changed to shoot a different subject.
The detection area using the SCD function can be set on this section. Up to 1 area can be set. When a shooting subject is changed in the set area, it will issue an alarm.
IMPORTANT
Since it takes time for necessary learning in the following period, the SCD will not function for a while.
Right after the SCD is set
After the power of this product is turned on
After a scene change is detected
The alarm occurrence indication button (→1.1.2 About the “Live” page) will be displayed when scene change is detected by the SCD function.
The alarm occurrence indication button will be displayed at a VMD alarm occurrence or when receiving a command alarm as well.
Depending on the network environment, notification may be delayed even when “Real time” is selected for “Status update mode” on the [Basic] tab of the “Basic” page. (→2.4.1 Configure the basic settings [Basic])
After configuring the SCD area, the SCD area may move out of alignment when “Image capture mode” of the [Image] tab is changed. Make sure to check the SCD area after changing the “Image capture mode” setting.
In the following cases, scene change may not be detected.
Only a part of the shooting area is covered or the covered object can be seen.
Subjects look alike each other before and after the camera direction has been changed.
In the area where the privacy zone is set.
The SCD function is not the dedicated function to prevent thefts, fires, etc.
We are not responsible for any accidents or damages that may occur.
When “Detection time” of “SCD area” is shorter than “Dwell time” of “Day & Night(IR)”, a scene change detection (SCD) may be activated at the time when an image is switched to BW. It can be improved by setting “Dwell time” of “Day & Night(IR)” shorter than “Detection time” of “SCD area”.
When the image color is close to monochrome, detection of SCD alarms may become difficult. When no alarms is detected, increase “Detection sensitivity” or set smaller “Detection area”.
