All-Weather Camera Doorbell – Designed to work reliably in rain, snow, and extreme cold. While the video doorbell wireless continues to operate in harsh conditions, please note that battery consumption may slightly increase in low temperatures.
Battery Consumption Linked to Recognition Process: The doorbell requires 4-5 seconds to detect and determine whether the activity is caused by a human, which consumes some battery. If set to "Human Detection Only" mode, non-human activity will not trigger video recording, but the recognition process still consumes battery power.
