Professional window alarm installation for New Jersey and Pennsylvania homes. Magnetic contact sensors, glass break detection, and smart home integration—all backed by 24/7 professional monitoring. Protect every entry point with sensors trusted by 10,000+ families.
Window alarms are sensors that detect when a window is opened or broken, triggering an immediate alert to your security system. As a critical component of any home security system, window sensors protect the entry points that burglars frequently target—statistics show 23% of break-ins occur through first-floor windows.
At Security Dynamics, we install professional-grade window alarm sensors as part of our complete intrusion detection systems. Unlike DIY alternatives, our sensors are professionally positioned, reduce false alarms, and integrate seamlessly with 24/7 monitoring—giving you reliable protection backed by 40 years of local expertise.
We install multiple sensor types to provide complete window protection based on your home's specific needs.
The most common window alarm type. A two-piece sensor—one on the frame, one on the window—creates a magnetic circuit. When opened, the circuit breaks and triggers the alarm.
Acoustic sensors that detect the specific frequency of breaking glass. Essential for catching intruders who smash through windows rather than opening them.
Hidden inside the window frame for a completely invisible installation. Ideal for homeowners who want protection without visible sensors.
While DIY window alarms are available at retailers, professional installation provides significant advantages for serious home protection.
Homeowners, families with children, anyone seeking insurance discounts and reliable protection
Renters, budget under $200, tech-savvy DIYers comfortable with self-monitoring

Professional installation ensures your window sensors are positioned correctly for maximum protection and minimum false alarms.
Our technician evaluates all windows, identifies vulnerabilities, and recommends the right sensor types for each. We assess window styles, frame materials, and room layouts.
Based on your assessment, we select the optimal mix of magnetic contacts, glass break sensors, and recessed sensors. We prioritize first-floor and accessible windows.
Our licensed technicians install sensors with precision placement, ensuring clean installation and proper wireless communication with your security panel.
Every sensor is tested individually and as part of your complete system. Glass break sensors are calibrated to prevent false alarms from pets or loud noises.
We show everyone how the system works, demonstrate the mobile app, and explain what happens when a sensor is triggered. Your system is live with 24/7 monitoring.
Common questions about window alarm sensors
Yes, window alarms are highly effective as part of a complete security system. Magnetic contact sensors detect when a window is opened, triggering an immediate alert to your monitoring center. Glass break sensors add protection against intruders who smash through windows without opening them. Statistics show homes with alarm systems are 300% less likely to be burglarized.
The best window alarm depends on your needs. For most homes, we recommend a combination of magnetic contact sensors on all openable windows plus acoustic glass break sensors for large window areas. Professional-grade sensors from brands like Honeywell and DSC outperform DIY alternatives with fewer false alarms and longer battery life. Professional installation ensures optimal placement.
Window alarm sensors use magnets to detect opening. A sensor on the window frame and a magnet on the window itself create a circuit when closed. When the window opens, the circuit breaks, triggering the alarm. Glass break sensors use acoustic microphones tuned to detect the specific frequency of breaking glass. Both types communicate wirelessly with your security panel.
Absolutely. Statistics show 56% of burglars enter through doors and 23% through first-floor windows. Door and window sensors are your first line of defense, alerting you the moment an entry point is breached. They also qualify you for homeowner insurance discounts of 10-20%, often paying for themselves within 2-3 years.
Professional window sensor installation typically costs $30-$75 per sensor, including the sensor, installation, and programming. Most homes need 8-15 window sensors. Glass break sensors cost $50-$100 each and can cover multiple windows in one room. Complete window protection for an average home runs $400-$800 as part of a full security system.
Yes, window alarms can be installed on virtually any window type including double-hung, casement, sliding, and awning windows. Surface-mount sensors work on most windows without modification. Recessed sensors can be installed inside the frame for a hidden appearance. Our technicians assess each window and recommend the best sensor type for your specific windows.
