Frequently Asked Questions
153
a. Check to see if the camera is positioned correctly (see positioning
recommendations in
Chapter 1: Installing Your iCVR
)
b. You can speed-up auto-calibration by walking in front of the camera and
giving the analytics a chance to learn your appearance. Over time, the
false alarms may decrease as the camera learns the correct appearance
of a human or vehicle.
2. If false alarms are occurring during a time of day when the region does not
need to be monitored, change the active time for the rule.
3. Reduce the shape of the Region of Interest (ROI) to avoid an object that
causes false alarms (e.g. drop the ROI below the horizon).
4. If possible, use a Region of Disinterest (ROD) to avoid the area where false
alarms are occurring.
5. Lower the sensitivity on rules
a. If the false alarms occur during certain times of day, a rule with lower
detection sensitivity can be defined just for that time period
b. If the false alarms are consistently of a particular type (i.e., all humans or
all vehicles), a separate rule can be defined for that type of object with a
lower detection sensitivity
6. If the false alarms last only briefly, change the rule activity to “Object is
present in ROI” for greater than 2 seconds.
