Dahua AirShield ARM9A4-P-W2 868Mhz

The Dahua AirShield ARM9A4-P-W2(868) is a sophisticated I/O expansion module that enables seamless integration between traditional wired security peripherals and the modern Dahua wireless ecosystem. It functions as a robust communication bridge, allowing you to incorporate reliable wired detectors and sirens into a new wireless alarm layout without the need for expensive re-cabling or infrastructure changes.

This unit is equipped with 16 alarm inputs that can handle various pulse and resistance detection modes, ensuring compatibility with almost any standard wired sensor on the market. Additionally, its 4 relay outputs provide the necessary interface to trigger existing sirens or manage local automation tasks directly from the Alarm Hub.

What sets the "P" model apart is its advanced networking capabilities. It can communicate with the central hub via high-stability 868 MHz radio frequency or through a wired Ethernet connection for maximum redundancy. Supporting PoE (Power over Ethernet), it simplifies installation by using a single cable for both data and power. With features like frequency hopping to prevent jamming, cloud-based updates, and a dedicated space for a 7Ah backup battery, this module is the ultimate tool for creating high-performance hybrid security systems.
