Dahua DHI-ARC3000H-FW2 Wireless Alarm Hub

Model: DHI-ARC3000H-FW2

Who This Is For

When building a scalable wireless alarm system is the priority, the Dahua ARC3000H-FW2 Wireless Alarm Hub is designed for installers and property managers who need a single control point capable of handling a large peripheral count without pulling cable. Supporting up to 150 wireless devices - keypads, sirens, detectors, and cameras - across a communication range of up to 2,000 metres in open space, it suits deployments that fixed-wire systems struggle to cover practically. The quad-path connectivity (4G, 3G, Wi-Fi, and Ethernet) with dual SIM support means communication continuity is built in from the start. Residential properties, villas, spacious commercial premises, and multi-zone industrial sites all sit within its scope. Remote arming, disarming, and monitoring through the DMSS app makes it relevant wherever the end user needs system control without being on-site.

What This Hub Actually Does

Who Buys This Model

• Security Installers on Large Residential Sites: Villas and acreage properties where cable runs are impractical - the 2,000 m open-space range and 150-device capacity cover the entire perimeter from one hub.
• Commercial Property Managers: Retail premises and office buildings that need remote arm/disarm capability without a staffed security desk - DMSS app control handles that from any smartphone.
• Integrators Building Dahua Ecosystems: Sites already running Dahua cameras benefit from the hub's confirmed integration with video surveillance, tying alarm events directly to camera feeds for verification.
• Industrial and Warehouse Operators: Facilities where fixed cabling to every detection point is cost-prohibitive - wireless peripherals at up to 2,000 m remove the need for trenching or conduit runs to outbuildings.
• Properties in Areas with Unreliable Fixed-Line Internet: Dual SIM plus 4G/3G fallback means the alarm system stays connected even when the primary Ethernet or Wi-Fi link goes down.

Honest Assessment

The ARC3000H-FW2 does the hard work in a wireless alarm deployment well. The 150-device capacity is genuinely large for a single hub, quad-path connectivity with dual SIM is a meaningful redundancy feature rather than a box-ticking exercise, and the 868 MHz frequency hopping approach handles RF congestion better than fixed-frequency designs. Cloud firmware updates are practical for installers maintaining multiple sites without repeated call-outs. This hub is stocked by Security Australia as part of the Dahua wireless alarm range.

What it will not do: it is not a wired alarm panel, so sites with existing hard-wired zone infrastructure will not get direct compatibility. It also relies on compatible Dahua wireless peripherals - it is not a universal hub for third-party alarm sensors. If the installation requires grade-rated alarm monitoring to a professional central station with specific compliance certifications, confirm those requirements against the product's certification documentation before specifying it.

Before You Buy

Quick Fit Check

• Good match if: You are installing a fully wireless alarm system using Dahua-compatible peripherals and need a hub with enough device capacity to cover a large residential or commercial site without running cable to every detection point.
• Good match if: The site has unreliable or shared internet and you need the alarm system to stay connected via cellular fallback - the dual SIM and 4G/3G support make mobile connectivity a built-in failsafe rather than an afterthought.
• You may need a different model if: The site runs existing hard-wired alarm zones or requires integration with non-Dahua wired detection hardware - a hybrid wired/wireless alarm panel would be a more appropriate product type for that scenario.

Real-World Scenarios

How It Compares

• Choose this if: You need a high-capacity wireless alarm hub with multi-path connectivity redundancy - the 150-device limit and dual SIM with 4G/3G fallback are not common at this product level.
• You may need a different model if: The installation includes existing hard-wired detection zones or requires a hybrid panel that accepts both wired inputs and wireless peripherals - a dedicated hybrid alarm panel would be the appropriate product type for that scenario.
• Pairs well with: Dahua-compatible 868 MHz wireless detectors, keypads, sirens, and panic buttons, along with Dahua IP cameras for integrated video verification of alarm events.

Common Questions

1. How many devices can the ARC3000H-FW2 actually support?

   Up to 150 wireless peripherals from a single hub. This includes a combination of keypads, PIR detectors, door/window contacts, sirens, cameras, and remote controls. For most residential and small commercial sites that number will never be reached, but for large villa complexes or multi-zone industrial sites the headroom matters when you are planning device counts across all zones up front.

2. What happens if the internet goes down - does the alarm system stop working?

   No. The hub supports 4G, 3G, Wi-Fi, and Ethernet simultaneously with dual SIM capability. If the Ethernet or Wi-Fi connection drops, the hub falls back to cellular automatically. As long as at least one communication path remains active, the system continues to report alarms and respond to remote commands through the DMSS app.

3. Will this hub work with non-Dahua alarm sensors I already have installed?

   No. The ARC3000H-FW2 operates on the Dahua proprietary 868 MHz wireless protocol with frequency hopping. It is designed for use with compatible Dahua wireless peripherals only. Third-party sensors from other alarm brands will not pair with this hub regardless of their operating frequency.

4. What is the real-world wireless range, and does it work through walls?

   The confirmed open-space range is 2,000 metres at 868 MHz. In practice, internal walls, concrete floors, and metal structures all reduce effective range. For typical domestic brick construction, plan for meaningful signal degradation through multiple walls. Where devices must penetrate heavy construction, position repeaters or use the open-space figure only as a maximum under clear line-of-sight conditions. The Security Australia product listing includes the hub's full specification sheet for reference when planning layouts.

5. Does the hub integrate with Dahua cameras, and what does that actually do?

   Yes. The ARC3000H-FW2 integrates with Dahua video surveillance systems. When an alarm event triggers, the integration allows the associated camera feed to be pulled up for visual verification. This means an alarm notification in the DMSS app can be paired with a live or recorded view of the triggered zone, allowing the user to determine whether the event requires immediate response before calling anyone out.

6. Does the hub require a subscription to use the DMSS app and cloud features?

   The DMSS app itself is free to download and supports direct device connection for remote arm/disarm and notifications. Cloud firmware updates are delivered through Dahua's cloud infrastructure. Confirm current subscription requirements for any advanced cloud storage or monitoring features directly with your supplier, as these can change with platform updates independent of the hardware specification.

7. What power supply does the hub need, and does it have battery backup?

   The hub runs on 12 V DC. There is no confirmed internal battery backup in the product specification. For sites where mains power interruptions are possible and continuous alarm operation is required, pair the hub with an external 12 V UPS or battery backup unit. This is particularly relevant for commercial and industrial sites where power cuts during an incident would otherwise leave the system without a power source.
