No obstructions,
such as trees,
vegetation, and
wire netting in the
detection area.
Not suitable. The target is blocked. (×)
Background
complexity
●
In scenes with
complex
background, the
target is hard to be
identified, and the
detection distance
will be shorter.
●
The larger the
temperature
difference between
the target and the
background, the
better the detection
result will be.
Not suitable. False alarm and missed alarm might be
caused, and the detection distance will be shorter.
