The built-in pressure equalization element of the device continuously equal-
izes the internal pressure of the device to the ambient pressure. Thus, the
temperature and humidity difference between the housing interior and the
ambient air is balanced, and hence the formation of condensation is largely
prevented.
Condensation Inside the Housing
Despite the built-in pressure equalization element, a sudden drop in tem-
perature (e.g. based on heavy showers or thunderstorms) may temporarily
cause water vapor (moisture) inside the housing, resulting in condensation
on the inner surface of the bubble as well as on the front glass element of
the camera lens.
In this case, activate the integrated heater manually via the WebConfig user
interface of the camera until all components are free of condensation again.
However, note that the built-in heater cannot be activated if the internal
housing temperature has ex60 °C (140 °F).
Condensation on the Outside of the Housing
Condensation on the outside of the housing may form temporarily – usually
in the early morning when the humidity level is high, as the ambient air is
warming faster than the outer surface of the housing.
This results in condensation on the outer surface of the polycarbonate bub-
ble (like dew on the grass).
This phenomenon is due to physical reasons and, therefore, does not consti-
tute a defect.
