Buying Guide for Alarm Magnets For Doors
Understanding Alarm Magnets
When I first heard about alarm magnets for doors, I was curious about how they worked. Essentially, these devices consist of two parts: a magnet and a sensor. When the door opens, the magnet moves away from the sensor, triggering an alarm. This simple yet effective mechanism provides an added layer of security that I found appealing.

4. **Battery Life**: I preferred models with long-lasting batteries. The last thing I wanted was for the alarm to fail due to a dead battery.
5. **Durability**: I looked for alarm magnets that were weather-resistant. If I planned to use them on exterior doors, I needed them to withstand the elements.
