More importantly, with the low-power consumption mode enabled, the battery can last 3~10 days without recharging, depending on how often the PIR sensor is triggered, and up to 100 days in deep sleep standby mode. | AI-Powered Human Shape Detection: With on-device smart AI technology, this small surveillance camera is able to differentiate people from other moving objects.
