Where Does the SimpliSafe Glass Break Sensor Go? A Comprehensive Guide for Optimal Protection

SimpliSafe’s glass break sensor is a vital component of a robust home security system, offering valuable protection against potential intruders. However, its effectiveness hinges on strategic placement. This article will guide you through the best locations for your glass break sensor, ensuring optimal coverage and peace of mind.

Understanding the Technology

The SimpliSafe glass break sensor operates using a sensitive microphone that detects the distinct sound of breaking glass. When triggered, it sends an alert to the SimpliSafe base station, which can then trigger an alarm, notify you via app, and even contact emergency services. To ensure accurate detection, it’s crucial to place the sensor in locations where it can effectively “hear” the sound of broken glass.

Best Placement Strategies

The key to maximizing your glass break sensor’s efficacy is strategic placement. Here are the key considerations:

1. Location: Proximity to Vulnerable Glass

The most obvious and crucial factor is proximity to the windows and glass doors you want to protect. The sensor should be within a reasonable distance for its microphone to pick up the sound of breaking glass. Generally, a distance of 10-15 feet is a good starting point.

2. Height: Eye-Level or Higher

The sensor’s placement height is critical. Ideally, you should position it at eye-level or higher, ensuring the microphone isn’t obstructed by furniture or other objects. This allows the sensor to capture the sound of breaking glass without any interference.

3. Avoiding Obstacles: Smooth Sound Propagation

Ensure the area between the sensor and the glass is free of obstructions that could dampen sound, like thick curtains or heavy furniture. The sensor needs a clear “line of sound” to effectively pick up the breaking glass.

Optimal Locations for Your Glass Break Sensor

Let’s delve into specific areas where your glass break sensor can be strategically placed:

1. Living Room and Family Room Windows

These areas often feature large windows, making them prime targets for intruders. Position your sensor near these windows, ensuring it’s at eye-level or higher, and avoiding obstructions like furniture or thick curtains.

2. Sliding Glass Doors

Sliding glass doors are particularly vulnerable due to their easy access. Place your sensor near the top of the sliding door track, ensuring it’s at eye-level or higher. This location allows the sensor to pick up the sound of breaking glass even if the door is partially open.

3. Bedrooms and Basement Windows

While less frequently targeted, bedrooms and basement windows shouldn’t be overlooked. Place your sensor near these windows, prioritizing locations with minimal sound-dampening obstacles.

4. Garage Doors

Garage doors are often a point of entry for burglars. Installing a glass break sensor near the garage door window, or even directly on the door itself, can provide additional security.

Additional Tips for Optimal Performance

1. Multiple Sensors for Enhanced Protection

For maximum security, consider installing multiple glass break sensors, especially if you have several vulnerable windows and doors. This provides comprehensive coverage and a higher likelihood of detecting a break-in.

2. Periodic Testing

To ensure your sensor is functioning correctly, test it regularly. This involves simulating a break-in scenario, like using a hammer on a piece of glass, to check if the sensor triggers an alert.

3. Sensor Placement Optimization

After installing your glass break sensor, take some time to observe its performance. If you find that it’s not triggering properly, you may need to adjust its placement or consider adding another sensor to improve coverage.
