Window sensors are a key component of most home security systems, designed to alert you when a window is opened or tampered with.
What are window sensors?
Window sensors are security devices that detect when a window is opened, tampered with, or broken. They’re a key component in any smart home alarm system.
How do window sensors work?
Most window sensors consist of two parts:
- A magnet installed on the moving part of the window
- A sensor placed on the window frame When the window is closed, the magnet and sensor are aligned. If the window opens and the magnet moves away, the sensor is triggered and sends an alert to the alarm system.

Do Verisure systems include window sensors?
Yes. Verisure’s smart alarm systems include window sensors as part of their Shock Sensor technology, which detects unusual vibrations or forceful impacts—often before a break-in occurs.
What makes Verisure window sensors different?
Verisure’s window sensors stand out thanks to their advanced technology, smart integration, and expert installation that together offer proactive protection.
- Shock detection: Advanced sensors identify break-in attempts before the window is fully opened or broken.
- Smart connectivity: Verisure sensors are connected to the Verisure Smart Alarm system, sending instant alerts to the 24/7 monitoring centre.
- Professional installation: Sensors are strategically placed by Verisure experts for maximum protection.
Can window sensors detect broken glass?
Verisure’s Shock Sensors can detect vibrations consistent with glass breaking, which helps trigger an early alarm—even if the intruder hasn’t entered the property yet.
Will I be notified if a window sensor is triggered?
Yes. If a sensor is activated, Verisure’s alarm system will send an instant alert to your smartphone via the Verisure app, and their monitoring centre will assess the threat and contact emergency services if necessary.
Are window sensors visible?
Verisure sensors are compact and discreet, blending in with most window frames while still offering powerful protection.
Can window sensors be installed on all types of windows?
Verisure’s professional team evaluates your property and installs sensors on various window types, including sash, casement, and sliding windows.
Are Verisure window sensors part of a wider smart system?
Absolutely. They work seamlessly with other Verisure products like motion detectors, cameras, and smart locks, creating a comprehensive smart home security solution.
