01Overview
What the DHI-ARD2231-W2 is
Dahua DHI-ARD2231-W2 combines PIR and microwave detection for an indoor wireless alarm system. This listing is for the white detector, with coverage reaching 12m across a 90° detection area.
Three sensitivity settings let an installer tune the response to the room. Pet immunity applies to animals up to 18kg and below 50cm when the detector is installed under the specified conditions.
Mount the unit at 2.2m, pair it with a compatible hub and walk-test the intended area. A CR123A battery powers the detector, with low-battery, tamper and temperature monitoring available through the configured system.
