NEW Outdoor Window & Door Sensors
Extend Your Outdoor Security
Expand your outdoor security perimeter with cutting-edge 2-way fully encrypted sensors. These tamper-resistant waterproof sensors protect detached structures that would typically be out of the wireless range of your security panel.

Intrusion detection security sensors
Monitor Your Doors and Windows
Secure and monitor any door or window in your home – from entryways to interior doors – with our perimeter alarm door contact sensors. Our smart sensors give you an added layer of protection from intrusion & burglary.

Intrusion detection security sensors
Get Notified to Unexpected Motion in Designated Areas
Place motion sensors in highly trafficked rooms, entryways, and other areas you’d like to monitor. When your system is armed and you’re away, any unexpected motion will sound an alarm.

Intrusion detection security sensors
Sound an Alarm if Glass Breaks
When glass is broken, the glass break detector triggers an alarm to alert both you and our Central Station of a potential emergency.

Water detection sensor
Be Alerted to Any Water Leaks
Water damage starts where you can’t see it: under sinks, behind washers, under water tanks and in attics and basements. Protect your home’s most vulnerable areas with wireless water sensors. They’re small, smart and always on guard.
