Power adapter
The general power adapter can only work reliably within the
temperature range of between 0
℃
to 40
℃
. If the power supply
is being operated outside this temperature range then this may
result in an unstable power supply being provided to the
camera.
Please replace with an industrial-grade power adapter if you
are using it in a harsh environment.
