Perimo Door and Window Sensor

Instant alerts the moment a door or window opens — no network setup required.

• Works without a network connection, so there's nothing complicated to configure
• Instant open/close alerts for doors, windows, cabinets, and other entry points
• Adhesive-backed install — no tools, no drilling
• Long battery life from a low-power design built for always-on monitoring

A simple way to add entry-point awareness to rentals, offices, and homes where a full alarm system isn't practical.
