Correct AND/W Setup Example
In the above example please notice that the And/W value number of the child zone is set to the detail
number of the parent zone. Also notice that the channel output (Ch/Out) of the child zone is set to NONE. It
is also of interest to notice that the parent zone is set up like any other zone, all the changes were made to
the child zone. The child zone will now place a call on the output channel of the parent zone (PROC:2 in this
example) when a vehicle is present on both zones at the same time.
To change the AND/W parameter, move the mouse cursor to AND/W and click either the left or right mouse
button to increment the AND/W values. When the desired value is selected, simply move the mouse cursor
to another zone parameter in the menu to set the value. The AND/W value is set to the same value as the
zone detail number by default, which effectively "OR's" the channel outputs. If you do not intend to use the
AND/W function, be sure that the AND/W value is set to the same value as the zone detail number.
Occlusion Rejection – This feature is recommended to be used when you want to minimize the effects of tall
trucks or tree shadows causing false calls in the left turn lanes.
Desensitize – If a zone is desensitized it will no longer participate in the dynamic three-stage algorithm most
of the time. If the camera is in LC then the desensitized zone will go into S3 mode. Care should be exercised
when turning on the desensitized option because it could lead to missed calls.
Pedestrian Rejection – As the name implies helps a zone reject pedestrian movement. Zones programmed
with Pedestrian rejection are less likely to false call due to pedestrian movement.
Bike Night S2 – Because of lighting conditions bicycles are harder to detect at night. Turning this attribute on
may help with missed calls in poor lighting conditions as it increases the sensitivity of the zone. The proper
solution is to improve the lighting at the intersection. The Bike zone will enter into S2 only when the system is
in night mode.
Bike Virtual Zone – If the camera is not mounted directly above the bike lane the Bike zone drawn may not be
rectangular but a parallelogram. Due to the position of the camera, the body of the bicycle rider may appear
out of the zone, and the call may be missed. This attribute will extend the zone in an attempt to capture the
rider. See figure below.
