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:
Crawling
Walking on all four (like an animal)
Camouflaged to look like an inanimate object (i.e., small tree)
Running and viewed from the side
Bent over and viewed from the side
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.
