Motion Detectors vs Glass Break Sensors: Which should I use?

8 Jul 2019

Both glass break detectors and motion sensors are great additions to a home that is protected by door and window sensors.

Door and window sensors will only activate an alarm if the actual door or window is opened, so even if you've got contacts on every door and window, you're still only partially protected.

A criminal that shatters a sliding door or window and then climbs through the opening would be able to walk freely through your home without ever tripping an alarm.

This is why it is imperative to have interior protection as well as exterior systems when you design your home defense layout. Read on to learn about these two simple devices that can provide you with an additional layer of protection. 

Glass Break Detectors

Similar to door or window sensors, a glass break detector is another form of perimeter protection. A glass break detector uses an audio microphone to pick up the audio frequency of broken glass.

If the security system is armed and hears the sound of glass breaking, it will automatically put the system into alarm and notify our central monitoring station.

Whereas door and window sensors protect the door or window from being forced open, glass break detectors protect against someone physically breaking the glass and climbing into your house.

If your home has big windows, sliding doors, or doors with nearby glass panels around it, these detectors are a great way to make your home defense system more robust.

Motion Detectors

Motion sensors are considered interior protection. While door, window, and glass break detectors protect against an intruder coming through a perimeter point, a motion sensor detects intruders regardless of how they got in.

As long as the intruder walks into a room that’s protected by a motion sensor, an alarm is activated. It is always recommended to have both perimeter and interior protection when upgrading your property with home defense in mind.

Motion sensors protect against a wider range of intrusion types. Some people avoid getting motions out of concern that their pet will set off a false alarm, but the good news is there are pet-immune motion sensors
out there that are safe for use with small and medium-sized dogs.
