A small motion sensor for keeping an eye on elderly people living alone. Alerts only when there is no movement. No installation required. No fees.

[Notifications Only in Case of Abnormalities] Attach the sensor to a door that is opened once a day, and a smartphone app will notify you only if there is no movement for a certain period of time. This provides just the right level of monitoring without requiring constant attention from the monitor. [Unobtrusive Sensor] The sensor is small and designed to blend in with any interior. Unlike cameras, it doesn't intimidate seniors, making them feel like they're being watched. [No Installation Required] Simply attach the sensor to the door with the included double-sided tape; no extensive installation is required. It can be used with sliding doors, so it's suitable for those living in Japanese-style rooms. [No Usage Fee] There are no monthly fees; all you need to do is purchase the device! It's easy to get started and can be continued for a long time. [Easy Maintenance] The sensor lasts for approximately one year with the push of a button, eliminating the need for frequent maintenance.
