Dahua ARC3000H-GW2 868MHz Wireless Alarm Hub Wi-Fi LAN Gateway

The ARC3000H hub is the intelligence of the Dahua wireless alarm system: all 868MHz wireless sensors, detectors, sirens, and expanders connect to the hub wirelessly, and the hub manages the alarm status, zone programming, user access, and communications.

The GW2 variant designates this hub’s communication capability: Wi-Fi and LAN (Ethernet) connectivity provides the network uplink for remote monitoring via the Dahua DMSS app, push notification alerts to registered users, and communication with the Dahua cloud platform. The Wi-Fi connection allows the hub to be installed without running an Ethernet cable to the hub position, while the LAN port provides a wired network option where a cable connection is preferred for reliability.

The 868MHz radio frequency is the standard for European and UK wireless alarm systems, providing the range and building penetration performance required for residential and commercial alarm installations. The ARC3000H hub manages the 868MHz bi-directional wireless communication with all paired devices, including regular device health checks and battery monitoring.

The distinction from the FW2 variant (DHI-ARC3000H-FW2) is the communication module: GW2 connects over the local network (Wi-Fi and LAN), while the FW2 includes cellular communication for communication without a fixed broadband connection.

For Dahua alarm system installers completing ARC3000H wireless alarm installations across London and the UK where Wi-Fi or LAN network connectivity is available at the installation, the ARC3000H-GW2 provides the standard gateway hub.
