In order to understand all of the above even better, please refer to the table below containing four
possible combinations of settings using sensitivity level and trigger threshold percentage.
The objects listed in each cell will trigger an alarm under given settings:
Low threshold (0-5%)
High threshold (5-100%)
Low sensitivity
(0-65)
Big and fast
Small and fast
Big and fast
High sensitivity
(65-100)
Big and fast
Big and slow
Small and fast
Small and slow
Big and fast
Big and slow
The device
’s default sensitivity is 70 and threshold is 10%. By these default values, only
the rabbit and the turtle would trigger an alarm
while the butterfly and the snail would be
ignored by the motion detection system.
Important:
Please remember that changing the size of the motion detection region has an impact
on the threshold
– the bigger is the size of the motion detection region the smaller should be the
threshold value if you want the same object size to trigger motion. For example, if you increase
the motion detection region to twice the previous size, please remember to reduce the threshold
to half its original value (from 10% to 5%). On the other hand, changing the location of the motion
detection region has no impact on threshold.
