⚫ Vertical (Vertical Detection Area)
This mode allows setting of a fan-like detection area in the vertical direction with a maximum radius of
30 m (Approx. 100 ft.), a spread angle of 180 degrees.
This mode creates a non detection area, 1.5 m (variable) immediately in front of the unit, in order to
avoid possible false alarms caused by birds or obstructions close to the unit.
Recommended installation height is from 4 m (Approx. 13 ft.) to 15 m (Approx. 50 ft.).
This mode will detect an object that traverses the detection area.
[Sensitivity] (Default: Middle)
The Sensitivity is to avoid false alarm caused by instantaneous event. If an object is detected longer than
the Sensitivity time, alarm is issued.
[Minimum Target Size (Width)] (Default: Middle)
The Size is to avoid false alarm caused by small object. If an object is smaller than Minimum Target Size,
the object is ignored.
[Detection Time] (Default: 10) (version 8.0.0 or later)
Can be changed when loitering detection is being selected. Specify a time from intrusion of an object in a
detection area to issuing an alarm.
