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.
