3.9 Reduced False Alarms

Firmware version 2.1.1 includes an algorithm that improves the identification of people who are standing
or moving upright in a scene. Previously, the system was designed to detect sophisticated intruders, for
example a camouflaged or crawling person. This capability is retained in this firmware. In addition, you can
enable the identification of upright people that will reduce false alarms (see below).
Note:
The following limitations apply to this function:
1. It is possible that a person who is not standing upright might not be detected
when:


2. The camera should not be facing straight down (i.e., it should be at a 30-40
degree angle from the object).
3. The smallest objects are 30 pixels high in the D1 video.
4. In scenes where the camera does not have good low-light sensors or thermal
sensors, detection might be reduced due to insufficient data.
To enable the identification of upright people
