The IP66-and NEMA 4X-rated AXIS Q1635-E offers aluminum and robust casing, sunshield to simplify installation time and costs. It is protected from dust, rain, snow and sun, and can operate in temperatures from -40 °C to 60 °C (-40 °F to 140 °F) using High PoE (30 W). The camera does not only function at -40 °C (-40 °F), but it can also power up at that temperature following a power failure. This feature is known as Axis Arctic Temperature Control. To guarantee heating, multiple heaters are placed in direct contact with the camera and the window. AXIS Q1635-E offers a dual shell technology, where an internal shell stores heat in cold environments. A fan ventilates the air in hot environments, where the heat is transferred to the outer aluminum chassis for efficient cooling.
