What Are Door Sensor Alarms and How Do They Work?
Door sensor alarms are security devices designed to detect unauthorized entry through doors, enhancing safety and peace of mind.
- Magnetic Door Sensors: These sensors consist of two parts: a magnet and a sensor. When the door is closed, the magnet and sensor are aligned, keeping the circuit closed; if the door opens, the circuit breaks, triggering the alarm.
