AirShield Magnet Pro: know when a door or window opens
The AirShield Magnet Pro is a compact wireless door and window contact designed for the longest battery life and the greatest range. With a battery that lasts up to 5 years and a range of up to 1,400 m, you can also place it in difficult locations without having to worry about it.
The AirShield Magnet Pro reliably reports whether a door or window is open or closed, with two-way communication, frequency hopping and cloud updates that recover on their own after a failed update. You choose white or black.
Why choose the AirShield Magnet Pro
Reliable open and closed detection
A reed contact immediately reports whether a door or window opens. Simple, stable and exactly what you expect from a magnetic contact.
Up to 5 years on one battery
The longest battery life in the range. Runs on a CR123A battery, included, with a notification when it is almost empty.
Bracket over the full length
The mounting bracket runs the full length of the detector and is secured with a tamper screw. As a result, it cannot simply be slid off without the alarm noticing. If you use adhesive instead of screws, you have the full length available to stick it down.
Greatest range
Up to 1,400 m in open field, thanks to two-way communication on 868 MHz with frequency hopping. Ideal for a shed or outbuilding.
Secure and self-recovering
AES128 encryption against eavesdropping, plus cloud updates that recover automatically if an update goes wrong.

Which magnetic contact suits you?
All three report whether a door or window is open or closed. The Magnet Pro has the longest battery life and the greatest range; the Magnet Plus already warns on vibration or forced entry, so before anyone is inside.
| Model | Detects | Shock / tilt | Wired input | Range | Battery |
|---|---|---|---|---|---|
| Magnet | Open / close | No | Yes (1x NO/NC/pulse) | Up to 1,200 m | CR123A, up to 4 years |
| Magnet Pro | Open / close | No | Yes (1 channel) | Up to 1,400 m | CR123A, up to 5 years |
| Magnet Plus | Open / close | Yes, shock and tilt | Yes (1x NO/NC/pulse) | Up to 1,200 m | CR123A, up to 3 years |
All three work wirelessly on 868 MHz with two-way communication and AES128 encryption, and pair with the same AirShield hub. Mount them on a non-metallic door or frame.
Notifications and expansion
An immediate notification in the DMSS app
As soon as a detector is triggered, the AirShield hub sends a push notification to your phone. In the free Dahua DMSS app you can see which detector was triggered and in which room, and you can arm and disarm your system. No subscription, on iPhone and Android.
No AirShield system yet?
This detector works with the wireless AirShield hub from Dahua. Put your system together room by room with the configurator, or have everything installed by our VEB-approved installers.
Frequently asked questions

For the longest battery life, up to 5 years, and the greatest range (up to 1,400 m). Useful in places where you do not want to replace batteries often or that are further from the hub.
Which doors is it suitable for?
For non-metallic doors and frames indoors. Keep the magnet distance below approximately 40 mm for correct detection.
What if an update fails?
The Magnet Pro works with cloud updates that recover on their own after a failed attempt, so you do not have to worry about them.
What is the difference from the Magnet Plus?
The Magnet Plus adds shock and tilt detection for the earliest warning. The Pro focuses on the longest battery life and the greatest range.
