necessary, wipe off any dust and frost
on it.
In cold weather, a special antifogging
coating can be applied (such as those
used on eyeglasses or car rearview
mirrors).
The device cannot
connect to a mobile
phone or computer.
The Wi-Fi password is
incorrect.
Enter the correct password.
There are too many Wi-Fi
networks in the range of the
device, which may cause
interference.
To enable stable network access, you
are advised to move the device to an
area with a limited number of Wi-Fi
networks, or an area without Wi-Fi
coverage.
Wi-Fi signals are lost or
interrupted.
The device is beyond Wi-Fi
coverage.
There is blocking (such as
concrete walls) between the
device and the receiver.
Move the device to a place where you
can receive Wi-Fi signals.
The observed target
disappears.
You are observing the target
through the glass.
Observe the target directly without the
presence of glass.
The image quality is
poor or the detection
range shortens.
These problems are likely to occur when you use the device in harsh
weather (such as snow, rain, and fog).
When the device is used
at a low temperature,
the imaging quality is
poorer than that at a
normal temperature.
At temperatures above 0°C, the temperature rise varies with the
observed objects (environment and background) due to different heat
conductivity coefficients. As a result, high-temperature contrast occurs
and the image quality is better.
At low temperatures, the observed targets (background) usually cool
down to a similar temperature because of reduced temperature contrast.
