Temperature resistance is a critical aspect of any security solution and should be considered when choosing a camera. Whether it is rain, ice,  snow, or heat, an outdoor surveillance camera is often up against extreme weather  conditions which can cause components to fail or freeze. Humidity
can also cause component damage such as condensation on the inside of
the camera during warm temperatures, and frost in cooler conditions.

The ArcticPro Series of extreme environment cameras combine temperature-tolerant components with a waterproof enclosure to
ensure flawless operation in temperatures as low as –40 °F
(–40 °C).
To be sure, you are specifying the right temperature rated camera, Dahua
data sheets specify a minimum and maximum operating temperature, as well as a storage temperature range. Extensive tests are performed to ensure
devices meet climate conditions.
