The following types of environment can impair performance, lead to damage, pose safety hazards and shorten the useful life of the camera. Select the sites for installing the storing the camera carefully.

Direct sunlight, rain or snow

Flammable or corrosive gasses

Very hot or cold (beyond -10 to 45 operating, -20 to 60 storage)

Humid or dusty

Exposed to vibration or shock

Strong electrical or magnetic fields

Exceptionally strong light

Continuous operation

In situations where the camera is used continuously for long periods of time, the ambient temperature should be kept below 40 in order to avoid accelerated deterioration of internal parts and to derive maximum long-term reliability.
