I am selling an aosu wireless intercom. This is a set consisting of the intercom unit (built-in battery) and a receiver (AC outlet) for indoor installation, allowing for immediate setup without any construction (the intercom unit can also be powered by a power supply instead of battery operation if construction is possible). It connects via Wi-Fi, enabling 24-hour monitoring from outside the home. - Brand: aosu - Type: Wireless Intercom - Features: Security camera, Wi-Fi, Battery-powered - Design: Compact and modern design - Installation method: Easy installation I will ship it immediately after purchase. Thank you for looking. #aosu #Wireless #Intercom #Wi-Fi #SecurityCamera
