Range - Sound Detection Technology - Compatible with The SimpliSafe Home Security System - Latest Gen : Electronics Review: Hope it works if needed. - Simplisafe is a damn good system. Hope I never hear any of it in use. All my doors and windows have Simplisafe sensors as well. This pretty much covers it. Everything is soo easy to install and program. Even a tech idiot like me had no problem installing any of it. Review: High quality system. Reliability of one component is my only concern. - I have a complete Simplisafe home security system and find it works well. Understandably, my main concern is reliability. I must be able to trust my system will perform without fail when needed. Yes, I can easily test for door and window openings and motion within protected areas but am somewhat unsure about my glass break sensors. In many home set-ups with large windows, protecting against glass-smash entries are critically important. Because of this, dependable glass break sensors are vital and part of a total security envelope. Because motion sensors are easy to test, I would prefer them but two things stop me from using them. (1) I prefer an intrusion alert before anybody actually enters my home. (2) Motion detectors are problematic with pets and roving house members. So, I employ glass break detectors in some areas. I have tested my Simplisafe glass break sensors using the recommended procedure and hand clap method and they always perform well. However, if I use a glass-smash sounds app on my phone at full volume the detections are hit or miss to say the least. Why is that? Now, I’ll admit that this may not be a true or fair assessment. I believe there could be technical reasons for the unpredictable results. Perhaps the smashing of a real plate glass window produces a sonic wave much more impactful than a recorded one from a tiny phone speaker. So, for now I’m going to take comfort in knowing the loud “hand clap’ tests did work and trust the Simplisafe technology which has been rock solid. As a confidence builder, I'd love to see a Simplisafe video demonstrating glass break sensors in action. ## Features - Glassbreak sensor - Detects the unique sound of breaking glass (up to 20 ft detection range) and triggers an alarm. - Get instant phone alerts - The SimpliSafe App notifies you if there's trouble. - Long-lasting battery - Simple set up - Peel and stick installation, place on a shelf or can install using included hardware.

Or is it always active?** A: You can set it in the app to work or not work in ALL modes. Completely tunable. I even use it to test when the system is off to send emails/texts or secret alerts when anyone walks in a certain room even when the alarm is off. **Q: Does this work with the Gen 1 system or is there an older glass break sensor available for that? Thanks** A: They recently decided to do away with the old system. They replaced all of my items for free with the new system. Call them. 😊 **Q: Will it work if door closed but window is within 20 feet?** A: The Glassbreak Sensor should be in the same room as the window you are protecting so it can pick up on the frequency of glass breaking clearly. **Q: How far can it be from the base?** A: All SimpliSafe components are battery-powered and communicate wirelessly with the Base Station, with a 400-500 foot range. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Hope it works if needed. *by T***Y on February 24, 2026* Simplisafe is a damn good system.
