[Environmental Resistance] (Outdoor mode Only)
⚫ Disable: Select it for applications to control PTZ camera. Response time of alarm is minimum but false
alarm can increase in harsh environment such as a fog or snow.
⚫ Enable: False alarm can be reduced by balanced detection ability.
⚫ Enhanced: False alarm due to fog or snow is reduced, but response time is long and some objects
may not be detected.
[Minimum Tracking Size]
If an object is smaller than Minimum Tracking Size, the object is ignored. After an object is detected, the
object is tracked while the size is larger than Minimum Tracking Size.
[Maximum Tracking Size]
If an object is bigger than Maximum Tracking Size, the object is ignored. After an object is detected, the
object is tracked while the size is smaller than Maximum Tracking Size.
[Non-Detection Zone (Ignoring Area from Ceiling)] (Vertical mode Only)
Objects near to ceiling are ignored. In vertical detection area, protruding objects on the ceiling can cause
false alarm. Enter the height of the ignoring area.
[Auto Area Adjustment]
REDSCAN continues to learn background area and update background information gradually.
By checking Adjust Detection Area, the detection area is adjusted proportionally to the background. (i.e.
False alarm by snow can be reduced.)
In vertical mode, learning area can be limited to Maximum Adjusting Height. Changes under the height are
learned as background.
In horizontal mode, learning area can be limited to Width of learning Perimeter. Changes in the perimeter
are learned as background.
