Window Alarm Types
- Magnetic Contact Sensors — Two-piece system sounds alarm when window opens. Best for detecting entry on sliding, double-hung, and casement windows.
- Vibration Sensors — Detects glass tapping, tampering, or breakage before an intruder fully enters. Adjustable sensitivity to reduce false alarms.
- 2-Pack Sensor Sets — Affordable multi-window coverage with adhesive installation and no tools required.
Contact Sensor vs. Vibration Sensor
- Choose Contact Sensor if: You want to detect window opening — alerts when an intruder enters
- Choose Vibration Sensor if: You want early warning — detects tampering and break attempts before entry
- Best approach: Layer both types on ground-floor windows for comprehensive coverage to include your door security alarms

- Rental Properties — Non-permanent security without landlord approval
Window Security Tips
