NG-MD10 is a Wi-Fi motion detector for home security: when motion is detected, alert notifications are sent to your phone so you can be aware of what's happening at home even when you're away. On standby, the battery can last 6-8 months, so it will not need to be replaced frequently. From the NGTeco Home all-in-one smart home app, you can handle various functions such as remote control, real-time alerts, and review history tracking. NG-MD10 is suitable for homes and offices.
