The Door/Window On-Site Alarm Host for Your Home

Forget to close door/window?

you to close the window when you are going to leave for work,
go to sleep or when it looks like to rain

The HEYI door/window alarm system allows
you to arm your home. Once the theft enters,
it will warn you at a very high voice(above 90dB).

Anti-Tampering and Damaging Design

The HEYI Door/Window alarm will inform you immediately
about any attempts to remove the host or open its case.
You can sure that you and your family are protected
