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.

04Why choose this

Built for the way you actually use the DHI-ARD2231-W2

Combine detection methods

Dahua DHI-ARD2231-W2 uses PIR and microwave sensing for indoor movement detection. Configure the sensitivity around the occupied space.

Plan around pets

Use the supported pet-immunity limits when choosing the installation position. Keep furniture and climbing routes clear of the detection pattern.

Monitor device condition

Tamper, low-battery and temperature monitoring help maintain the configured alarm system. Check notifications during handover.

05Where it fits

Right at home in these scenarios

Indoor access routes

Dahua DHI-ARD2231-W2 can monitor movement through an internal hall or entrance area. Position it so people cross the detection pattern.

Rooms with pets

Check animal size, mounting height and the room layout before relying on pet immunity. Walk-test with normal household activity.

Wireless alarm extensions

Add the detector to a compatible hub after checking the regional radio version and available system capacity.

    Pair Dahua DHI-ARD2231-W2 with a compatible alarm hub and matching regional radio version. Confirm communication at the planned location.

  2. Mount and align

    Install at the specified height and set sensitivity for the room. Avoid obstructions that interrupt the detection pattern.

  3. Test before arming

    Perform a walk test, check tamper reporting and confirm alarm notifications. Repeat checks after changing the room layout.
