It supports flexible power through either the rechargeable battery (via Type-C port) or a hardwired AC power supply (8-24VAC) for non-stop operation. The device is IP65 rated for professional water and dust resistance, ensuring stable performance in adverse weather.

∎ 【Seamless Connectivity and Convenience】The doorbell is equipped with Wi-Fi 6 standards, ensuring efficient, fast, and stable video transmission with lower lag.
