Window Alarm Types Explained:
Magnetic Contact Sensors
How it works: Two-piece system - sensor on frame, magnet on window. When window opens, magnetic contact breaks and alarm sounds.
Best for: Detecting window opening - alerts when intruder enters
Limitation: Does not detect glass breakage if intruder breaks glass without opening window
Vibration Sensors
How it works: Detects vibration/shock from attempted break-in, glass tapping, or breakage. Sounds alarm immediately.
Best for: Early warning before entry - detects tampering and break attempts
Limitation: May trigger false alarms from strong wind, nearby construction, or loud noises (adjustable sensitivity helps)
Installation Instructions:
Magnetic Contact Sensors
- Clean window frame and sash with rubbing alcohol
- Attach sensor unit to window frame (stationary)
- Attach magnet to window sash (moving part) aligned with sensor
- Test by opening window - alarm should sound
- Adjust magnet position if needed for proper alignment
Vibration Sensors
- Clean window glass surface
- Attach sensor directly to glass pane with adhesive
- Adjust sensitivity dial (if available)
- Test by tapping glass - alarm should sound
- Fine-tune sensitivity to avoid false alarms
Best Uses for Window Alarms:
- Ground Floor Windows: Most vulnerable entry points - protect all accessible windows
- Basement Windows: Often overlooked but easy access for intruders
- Sliding Windows: Magnetic sensors work well on sliding window tracks
- Large Windows/Patio Doors: Glass break sensors for large glass surfaces
- Bedroom Windows: Personal safety while sleeping
- Vacation Homes: Alert to entry when property unoccupied
- Rental Properties: Non-permanent security without landlord approval
Window Security Tips:
- Secure all ground-floor and basement windows with alarms
- Use vibration sensors on large glass surfaces (patio doors, picture windows)
- Use contact sensors on opening windows (double-hung, sliding, casement)
- Layer protection: contact sensor + vibration sensor for comprehensive coverage
- Test alarms monthly to ensure battery function
- Replace batteries annually or when low-battery indicator sounds
- Add window locks or blocking bars for physical security in addition to alarms
How Many Window Alarms Do You Need?
- Minimum: All ground-floor accessible windows (typically 4-8 windows)
- Recommended: All ground-floor + basement windows (8-12 windows)
- Comprehensive: All windows on accessible floors + second-floor near climbing access (12-20+ windows)
- Budget Approach: Start with most vulnerable windows (front/back of house, hidden from street view)
