Notice!
Alarm Repeater Pro is only compatible with the ARC3800H series hubs.
The Dahua ARA46-N-W2(868) is a professional wireless alarm repeater that significantly increases communication between the alarm hub and wireless security devices. Designed for use within Dahua alarm systems, the device provides a stable and reliable connection even in larger buildings or installations where the range of the hub alone is not sufficient.
By supporting RF, Wi-Fi and Ethernet, the repeater can use multiple communication channels simultaneously. This increases system reliability and minimizes the risk of signal loss. Two-way communication and frequency hopping keep the connection stable and secure, while AES128 encryption protects against unauthorized access.
The repeater supports up to 128 wireless devices and can transmit signals up to 2,000 meters in open field (Airfly mode). This makes it ideal for larger homes, commercial properties or more complex security installations.
An integrated 4750 mAh lithium backup battery ensures that the system continues to function during power outages, with a standby time of up to approximately 35 hours. Additionally, the device supports cloud updates, automatic or manual pairing of peripherals and offline pairing for added system security.
With its compact housing and wall or table mounting capability, the ARA46-N-W2 is easy to install and suitable for a variety of security environments.
