Do you hear what I hear?

The IQ Glass break detector hears when your window breaks and sounds the alarm.

More than one way to enter a window

To break in through a window, an intruder can either pry it open or break the glass. Door/window sensors detect when a window is pried open but you need a motion detector or glass break detector to catch them breaking the glass.

Let a big dog roam

Motion detectors are only pet immune for small and medium size pets. With the IQ Glass you can arm your system and let your large dog roam free without triggering an alarm.

Multiple layers of protection

Want to be extra sure an intrusion will be detected? Use a glass break detector along with door/window sensors and a motion detector for double detection.

Detect intrusions with Surety

If you’re going to use a security alarm, choose a professional grade glass break detector with secure wireless communication so you can be confident it will do it’s job.

Why should I use encrypted sensors?

The majority of security systems are not as secure as they could be. With technology advancing rapidly, it’s becoming more and more likely that someone who wants to compromise your security system can do so without much effort or expense.

IQ encrypted sensors send signals in a coded form that can only be understood by the alarm system they are connected to. This ensures that only your system can access the content of the message, keeping your sensor activity data safe and practically eliminating your system’s exposure to spoofing and replay attacks.
