Dahua ARA46-N-W2 Network and Wireless Alarm Repeater Pro

Overview

The Dahua ARA46-N-W2 Alarm Repeater Pro is a mains-powered range extender for the Dahua ARC3800H wireless alarm series. It links back to the hub over Ethernet, Wi-Fi and radio at the same time, so the connection stays up if one path fails. It suits a large home, a multi-floor office, a retail chain or a warehouse, and it lets a distant building join the alarm over the existing network rather than radio alone.

Is it right for you?

• It suits an ARC3800H series hub only. It will not work as a repeater for the ARC3000H hub.
• It suits a separate building or a far floor that already has a network connection, because the Ethernet or Wi-Fi link carries the alarm signals where radio cannot.
• If you only need to extend radio range on an ARC3000H system, the ARA43-W2 repeater is the matching model.
• Charging is limited to 0 to 45 °C, so it is not for a hot ceiling void or rooftop room.

Key features

• Relays up to 128 wireless peripherals.
• Airfly radio range up to 1,600 m in open space, RF-HD normal speed up to 1,200 m and RF-HD high-speed mode up to 300 m.
• One RJ-45 10/100 Mbps Ethernet port and Wi-Fi (IEEE 802.11b/g/n/ax), so it can reach the hub over the network as well as by radio.
• Forwards image and audio data from camera detectors and intercom sirens.
• Offline linkage (local automation) keeps scenes running if the link to the hub drops.
• System backup with automatic rollback after a failed upgrade.
• Built-in 4,750 mAh lithium battery: up to 35 hours of standby on radio only, or 18 hours when connected over the network or high-speed RF-HD.
• Two-way, frequency-hopping radio with AES128 (Advanced Encryption Standard) encryption, tamper detection and low battery detection.

What else you need

A Dahua ARC3800H series hub, a mains socket (100 to 240 V AC, 50/60 Hz, up to 22 W), and a network cable or Wi-Fi network if you want the network path. Pairing and cloud updates use the Dahua app.

Installation

An alarm installer can survey and set it up. Install it indoors on a wall or a desk, within the operating range of -10 to 50 °C (0 to 45 °C while the battery is charging), connect mains and, if used, the Ethernet cable, then pair it from the Dahua app.

Software and licences

The Dahua app is used for pairing and for cloud firmware updates.

Before you buy

• Compatible with the ARC3800H hub series only, not the ARC3000H.
• Avoid hot locations: the battery charges only between 0 and 45 °C.
• Standby time drops from 35 hours to 18 hours when the network path or high-speed RF-HD is in use.
