11.4 Creating Detection Zones with Different Sensitivity
By default, every zone is set to a sensitivity setting of medium. The sensitivity settings control the overall
tracking capability of the radar. There are three settings, High, Medium and Low. See Section 12 for more
information on these sensitivity settings. In 99% of cases, the medium setting will work well and should not be
changed. However, in some very specific circumstances it may be necessary to increase or decrease sensitivity.
Typically, high sensitivity can be used in areas where the radar is struggling to track targets. This could be for
a number of reasons, but a typical example would be where targets are partially obscured because the ground
drops away, so the radar can only see the top half of a target. This makes it harder for the radar to detect the
target and therefore increasing sensitivity will help.
Note: The High sensitivity setting can lead to a significant increase in false alarms making the system less
effective as a fully automated camera. Therefore, it is recommended that High sensitivity is used only when
required, is only used in small zones where the extra detection capability is required and is tested thoroughly
over a period of time to ascertain where the false alarm rate is acceptable.
The reverse is true of using low sensitivity. This setting will it make it harder for the radar to detect targets. This
can be used in areas where normal targets, such as people and vehicles are being tracked well, but you are
experiencing nuisance or false alarms. Reducing sensitivity will help exclude smaller targets, such as wildlife.
Note: Reducing sensitivity may have an impact on the detection and tracking of genuine targets. So this setting
should only be used when required, only used in small zones where the detection capability is better than
required and is tested thoroughly over a period of time to ascertain where the detection and tracking remains
acceptable.
An example of using different zones for varying levels of sensitivity might look like this:
Secure
Building
Zone 1(Low)
Vegetation
Zone 2
(Medium)
Trees
Zone 3
(High)
Lower
Ground
Radar
Drop in Ground
Only 50% on the person can be
seen by the radar. Increasing
sensitivity will help the radar detect
this partially obscured target
