Please note extreme cold weather may cause eufy battery-powered Video Doorbell to temporarily stop functioning since its operating temperature range is -4°F to 122°F / -20°C to 50°C due to the built-in lithium-ion battery. However, eufy battery-powered Video Doorbell will automatically resume working normally once temperature becomes warmer and falls within the device’s operating temperature range.

Note: Due to the working mechanism of Passive Infrared (PIR) sensor, eufy battery-powered Video Doorbell may not be functioning as sensitive when detecting motion in cold weather conditions. Therefore, it is highly recommended to increase eufy battery-powered Video Doorbell’s motion detection sensitivity level in the wintertime even if the current motion detection sensitivity setting works without issues in the summertime.
