About the image recognition function

AVMD, which is one of the image recognition functions, are featured in this unit.

It is possible to detect moving, abandoned, or removed objects in the shooting area by setting the detection program in advance. (☞ page 34)

When an abandoned or removed object is detected, the frame and track, are displayed on the live images. (☞ page 12)

Auto track for the detected object is also possible using another analog camera. (☞ page 41)

It is also possible to specify the range of people’s motion and the size of detected object by setting the detection depth.

AVMD can be activated for up to 2 channels at the same time.

Intruder detection

The motion of object is detected in the shooting area of the channel for which the AVMD is activated.

Up to 8 objects can be detected simultaneously per channel. It is impossible to recognize 9 objects or more. (Depending on the size of moving object, less than 8 objects can be detected.)

The detection status will be canceled when the moving object goes out of the shooting area.

By setting the intruder detection area (☞ page 34), it is possible to activate an alarm when a moving object goes into the area. (To prevent false notifications, it is necessary for the object to be detected as a moving object for 2 sec- onds or more.)

Detection of abandoned or removed objects

By setting the detection area of object abandonment / removal (☞ page 34) in the shooting area of the channel for which the AVMD is activated, it is possible to activate an alarm when an object is abandoned in the area or removed from the area. (To prevent false notifications, it is necessary for the object to be detected as an abandoned or removed object for 20 seconds or more.)

Up to 8 objects can be detected simultaneously per channel. It is impossible to recognize 9 people or more. The detection status will be canceled when around 40 seconds have passed after the detection.

Important:

AVMD will be activated even after the camera moves or is moving from the selected preset position. To prevent false notifications, it is recommended not to move the camera connected to the channel for which the AVMD is activated.

About AVMD (Advanced Video Motion Detection)

AVMD of this unit is the image recognition function that detects motion based on the luminance transition in a desig- nated area. Under the following circumstances, AVMD may not be activated properly.

•There is no difference in luminance level between the moving object and background.

•Luminance level of image is too low (During nighttime, etc.)

•Movement of object is too fast or too slow.

•Object is too big or too small.

•Luminance level of shooting area is subject to change (outdoors, by the window, etc.)

•Outside light (sunlight, headlights, etc.) enters the shooting area.

•Fluorescent light is flickering.

•Depth of object is too long.

•Dirt, drip, or splash is on the dome cover of camera.

•Object is moving directly toward the camera.

•Too many objects are moving.

•Camera is shaking.
