Image recognition
This unit is equipped with the following image recognition functions. Presetting of detection conditions allows
this unit to detect human intrusion, abandoning an object, and removing an object on a screen. When human
intrusion, abandoning an object, or removing an object is detected, the detection frame and trajectory can be
displayed on the screen.
In addition, by setting the human size, it is also possible to designate the size of an object and the motion range
of a human. Up to 2 cameras can be simultaneously operated for the image recognition function.
Intrusion detection
The motion of an object is detected on the image that is shot by the intrusion detecting camera.
Presetting of an intrusion detection area allows an alarm to be issued when a moving object intrudes into the
area. (To prevent a false alarm, the moving object needs to be detected for 2 sec. or more as a moving object
to issue an alarm.)
Up to 8 moving objects can be simultaneously detected by 1 camera. A 9th or higher object cannot be
detected. (The detectable maximum number may be less than 8 depending on the size of moving objects.)
The detected status is cancelled when the moving object moves out of the screen (when alarm automatic can-
cellation is activated).
Object abandonment/removal detection
This function detects object abandoning/removing on images via the cameras with which object abandonment/
removal detection is performed.
Presetting of the areas of object abandonment/removal detection allows an alarm to be issued when object
abandonment/removal occurs in the areas. (To issue an alarm, the status of object abandonment/removal
needs to last for 10 sec. or more.)
Up to 8 object abandonment/removal can be simultaneously detected by 1 camera. A 9th or higher object can-
not be detected. The detected status is cancelled approx. 60 sec. after detection (when alarm automatic can-
cellation is activated).
Important:
• You are recommended not to move the direction of the camera that is performing intrusion detection to pre-
vent a false alarm.
• A movement is hard to be detected or cannot be detected, or a malfunction is caused in the following
cases:
No difference in brightness between a background and a foreground
Water droplets or stains attached on the camera dome
Insufficient brightness, for example, when shooting at night
The object is moving straight at the camera
The object is moving too fast or too slow.
The object is too small or too large.
There are too many moving objects
Variable light state, for example, in outdoors and at the window
The camera is shaking.
Entry of outside light, such as sunlight or the headlights of a car
Remarkably bad weather conditions
Flickering fluorescent light
Object with a depth
• For intrusion detection setting, perform area setting in accordance with camera installation conditions and
expected object movements, and then perform the operation check in the daytime and nighttime. If nothing
is detected or false detection occurs, use another sensor (option).
• Object abandonment/removal detection is dependent on fluctuation in brightness. Therefore, use of this
function at places where brightness is stable is recommended.
