Possible cause
You are looking through glass.
Solution
Remove the glass or change the viewing position to avoid it.
Poor image quality / Detection range reduced
Possible cause
These problems may occur during observation in adverse weather conditions (snow,
rain, fog, etc.).
The image quality during the device operation at below
zero temperatures is worse than at positive temperatures
Possible cause
In positive temperature conditions, objects being observed (surroundings and
background) heat up differently because of thermal conductivity, thereby
generating a high temperature contrast. Consequently, the image quality produced
by the thermal imager will be better.
In low-temperature conditions, objects being observed (background) will cool down
to roughly the same temperature, which leads to a greatly reduced temperature
contrast and a degraded image quality. This is normal for all thermal imaging
devices.
Smartphone or tablet PC cannot be connected to the device
Possible cause
Device password has been changed.
Solution
Delete the network and connect again using the password saved in the device.
