Setting the Object
Detection Function

— Object detection Menu

When you click Object detection in the Administrator
menu, the Object detection menu appears.
Using this menu, you can set the conditions for
activating the built-in "Moving object detection" and the
"Unattended object detection" functions. Moving object
detection detects moving objects in the camera image
and outputs an alarm. Unattended object detection
detects difference between the previously shot
background image and the image being shot currently
and outputs an alarm when the difference continues
recognized for more than the specified period.
The Object detection menu consists of three tabs:
Common, Unattended object setting and
Configuration.
What is unattended object
detection ?
The unattended object detection function of this unit
compares the reference background image with the
current image to detect an unattended object. The unit
can perform "Abandoned object detection" of an object
that did not exist and appears now as an unattended
object. The unit can also perform "Removed object
detection" of an object that existed before and now has
disappeared as an unattended object.
Abandoned object detection
The camera first stores in memory the background
image for reference. If an object that did not exist before
appears on the background and stops, the camera detects
the object as an unattended object. If the unattended
object stays in camera image for more than the specified
time, it is marked with a red frame and an alarm linked
to unattended object detection is output. you can activate
alarm sending of the FTP client function, alarm
recording of the image memory function and playback
of an audio file in synchronization with the alarm.
