Dahua DHI-ARA12-W2(868) — Wireless Indoor Siren with Temperature Measurement
The Dahua DHI-ARA12-W2(868) is a wireless indoor siren that sounds an audible alarm and helps deter intruders as part of a Dahua wireless alarm system. It communicates on the 868MHz band using two-way, frequency-hopping communication with AES128 encryption for a stable and secure link to the alarm hub, and it also reports temperature readings back to the system.
Who is it for?
This siren is intended for use inside a property as the audible alarm output of a Dahua wireless intruder alarm system, sounding when the system is triggered by a connected detector.
