lomeh 0 Posted October 21, 2020 Hi , I have a IP box cam that runs from -40 to +70 °C (-40 °F to +158 °F) with 95% humidity . The Cam is not environmentally protected and I want to install it outdoors . So I want to buy a housing. I have 2 options : A heater blower and no heater housing. both rated at IP66. The installation place temperature is between 0°C (32°F) up to 20°C (68°F) in winter . Relative humidity is from 60% to 80% according to https://weather-and-climate.com/ First Question , Do i need a Heated Enclosure ? (to prevent glass from fogging and whatnot) Seconds Question : Does (glass Fogging) happen at certain time (sunrise maybe?) for example if the camera is day only (no night or IR ) do I need to care about heated housing ? Third Question: If I need a heated Housing , what is the duty cycle operation of the heater ( i know this is very technical ) . In other-words does it stay on all the time ? Thanks and best regards Share this post Link to post Share on other sites
