Build your custom Dahua wireless alarm system online
Design a complete Dahua AirShield wireless alarm system in minutes. Start with a system base — a ready-to-arm ARC3800H kit or just the bare hub if you prefer to build from scratch — then add wireless PIR motion detectors and door/window contacts, sirens, a keypad and remotes. Every device pairs to the hub wirelessly, so there's no alarm cabling to run. The ARC3800H hub includes Wi-Fi, Ethernet and 4G LTE backup with battery backup, and is self-monitored through the free DMSS app — the same app as your Dahua cameras. All genuine Dahua Australian stock with warranty and free local tech support. Add to cart or request a tailored quote.

Dahua alarm — frequently asked questions
Do I need a separate monitoring contract?
No. The Dahua AirShield system is self-monitored by default — arm, disarm and receive instant push notifications through the free DMSS app on your phone, with no monthly fee. If you'd like professional back-to-base monitoring, our team can arrange it on a quote.
How many detectors can the hub support?
The ARC3800H hub supports a large number of wireless devices across multiple arming areas — more than enough for a typical home or small business. Start with a kit and keep adding detectors, sirens and remotes as you grow. We'll confirm the exact device count for big sites on your quote.
Will it still work if the power or internet drops?
Yes. The hub has a built-in rechargeable battery backup and 4G LTE cellular backup, so it keeps arming and sending alerts even if mains power or your home Wi-Fi/NBN goes down.
Can I link the alarm to my Dahua cameras?
Yes. Both the AirShield alarm and Dahua CCTV run in the one DMSS app, so a triggered detector can pull up live camera footage and you manage everything from a single dashboard.
Are these genuine Australian-stock Dahua alarms?
Yes. Every hub, kit, detector and accessory is genuine Dahua Australian stock, backed by warranty and shipped Australia-wide with free local tech support.
