Troubles
Possible Cause
Solutions
Images are blurred
No image calibration for
a long time
Click the shutter correction button
in the software
Camera can’t be started
The supply voltage
exceeds the normal
working supply voltage
range
Check whether the power supply
voltage is between 9 and 26V
The power connector is
loose
Check whether the power cable is
connected
Inaccurate temperature
measurement
The stabilization time
for thermal camera is
too short.
Keep the thermal camera stable for
more than 10 minutes.

Power cable or network
cable connection is
loose.
After checking the power supply
and network cable connection,
preview the images again.
Images cannot be
previewed.
The camera is not
