    Finally, I can relax

Frequently Asked Questions

How does it work?

Each Home Guard sensor has two magnetic pieces: one mounts to the frame, the other to the door or window itself. When they separate, a built-in alarm sounds instantly — no app, no wifi, no subscription required.

How many sensors do I need?

Most families use one sensor per external door or window they want to monitor. Our bundles make it affordable to cover every entry point, including pool gates and cabinets.

Is installation difficult?

Not at all. Peel off the adhesive backing and stick both pieces in place — no drilling, no wiring, no tools. Most parents have it installed in under 5 minutes.

How long does the battery last?

Each sensor is built for long-lasting, worry-free use with a low battery LED indicator, so you'll always know when it's time for a replacement.
