Hikvision AX PRO wireless magnetic detectors consist of two parts: a reed relay and a magnet in a separate housing. A reed relay is an electrical contact in a sealed container that closes when the magnet approaches and opens when the magnet moves away. In this way, the sensor registers both opening and closing and the alarm system can notify users.
Sensors for doors and windows are an essential part of many alarm systems. They can activate alarm signals via the AX PRO alarm system, run automation scenarios and integrate sensors from third parties. All these functions make the detectors an important part of a smart home.
