Strengthen your home’s door and window security with these small, but mighty sensors. You’ll always know if an entrance is exposed. Accidentally left a door or window open? Potential break in? Your sensors are on it. They’ll immediately send a wireless signal to your Frontpoint Hub, triggering a high-decibel alarm that you — and any intruders — won’t miss. You’ll also receive an instant security alert on your smartphone via the Frontpoint mobile app.
