Long range. Our glass break sensor is here to provide an extra layer of protection. The sensor inside each device “hears” the sound of cracked and shattered glass.

Just installed my new Cove system: 18 window/door sensors, motion detector, glass break sensor, and 2 key remotes. All well worth it. Everything works well, and I’m very satisfied. **Rich** My alarm went off two days ago, and I was so nervous when the call center phoned me that I gave the wrong safe word. So, police were dispatched. Something had fallen inside my home, which caused the glass break sensor to set off the alarm. So, we learned the alarm does, in fact, work well! **Darlene C.** The day the Blue Angels were preparing for an air show, they set off the glass break sensor and rattled the whole house. We received a text and a phone call from Cove within 1-2 minutes, and it took authorities 5 minutes to arrive. The monitoring center did an excellent job. They asked the right questions and made me feel they really were concerned for my property. **Timothy W.** ## Know what’s happening right away. Use the Cove Connect app to check in on your home’s doors and windows no matter where you are.

Because we don’t cut corners when it comes to taking care of your home. ### Long Life With up to 5 years of battery life, you can install your glass break sensor and forget about it. It’s self-testing, so it’ll let you know when it’s time to change the battery. ### Tamper Resistance This sensor is tamper-resistant, making it easy to install and difficult for an intruder to disable. ### System Connectivity Our glass break sensor connects to your hub via a wireless radio connection, not Wi-Fi.

Window sensors could probably more accurately be referred to as “window opening sensors,” while glass break sensors could be referred to as “window breaking sensors.” Glass break sensors work differently. Instead of sensing the opening and closing of a window, they sense the window breaking. A glass break sensor is placed on the wall opposite a window, and it’s a lot like an ear. It “hears” the frequency of breaking glass. **Do glass break sensors really work?** Yes! Glass break sensors really can sense breaking glass! As long as your sensor is directly facing your windows and is within 15 feet, the audio recognition technology inside the sensor will notify you if your window breaks. These sensors are especially useful as an extra layer of protection or for second-story windows. **Can a dog bark set off a glass break sensor?** If the frequency at which your dog barks matches the frequency of breaking glass, it is technically possible that this could set off a glass break sensor. This is not a common occurrence, but if it happens to you, please reach out to our customer service team. **How can I test a glass break sensor?** Our glass break detector includes a test button, so you can ensure that your sensor is communicating with your panel at all times.
