Does anyone had fog or frost problem went installing the Avigilon H3-PD1 series during cold weather? We are located in a northern region where the temperature can go to -30 degrees Celsius (-22 Fahrenheit) in the winter. Since the last autumn almost half the Avigilon H3-PD1 that we have installed are getting foggy periodically. The fog comes and goes. We have some of the cameras that never had fog even if they are located few feet from the problematic cameras. We also install other types of cameras (Hikvision, Bosch) in the same condition without any similar problem.
[IPVM Update: It was an installation problem, confirmed and explained below.]
