The alarm duration can be freely set between 1 to 180 seconds to match your installation environment and intended use.

◆Link with Other Smart Products

Through the dedicated app, it can be linked with other Kashimura smart products. For example, you can set it up so that "when the motion sensor detects movement, the smart camera starts recording."

Words from the Development and PR Representatives

The "alarm sound from the unit" and "detection notification to smartphone" when human movement is detected are not only useful for crime prevention but can also be used for family monitoring by turning off the alarm sound in the app.

Furthermore, setup is simple with just "power (batteries or USB), smartphone, and Wi-Fi," so even those who are intimidated by "smart home products" can start without hesitation.

We hope this product, which can be easily introduced and used in a wide range of situations according to your needs, will be of service to your daily life. (Development Representative)

Worried about whether your family living far away is doing well, but calling every day feels like a burden for both of you...

In such cases, placing this sensor in the living room of your parents' home, for example, allows you to subtly understand their daily activities through smartphone notifications.

This is an item that allows you to monitor your precious family members living apart with a comfortable sense of distance. Please make use of it! (PR Representative)
