Yes, it works even in cloudy or rainy weather!
Wyze Solar Cam Pan is equipped with a 6400 mAh lithium-ion battery, which allows the camera to operate through cloudy or rainy days without solar charging. The camera's battery life will last 2-6 months under normal usage.
Please note that solar charging will pause to protect the battery when the outside temperature drops below 32° F (0° C).
