When the topic of temperature and trail cameras is discussed there are two areas of interest. Below we have provided the information for both.
Safe Operating Temperatures
Browning Trail Cameras are designed to be left outside for long periods of time and are built to withstand a range of temperatures. Extreme temperatures however may cause harm to the camera. These extremes are anything over 130° F and anything below -30° F.
Performance Temperatures
Browning Trail Cameras use a PIR (Passive Infrared Sensor) for detection. This means the camera is not solely looking for motion to trigger but also a variance in temperature. Thusly when it is hotter than normal outside and everything is hot the trail camera may take longer to see a variance in temperature and that applies to the cold as well.
Below are a few articles that relate to this topic for more information.
