The Dahua ARD2231-W2(868)-B motion sensor combines passive infrared detection (PIR) and microwave detection (MW) for indoor and outdoor use. Its dual technology helps reduce false alarms, while PIR detection covers up to 12 m at a 90° angle. PET immunity allows pets weighing up to 18 kg and measuring less than 50 cm in height.

The sensor uses 24 GHz...

  • Connectivity

    Refers to the wireless communication protocol used by the sensor to connect with other alarm systems or devices.

  • Login

    Wireless

    It connects wirelessly via a wireless communication protocol to the installation system. It is powered by a battery.

  • Detection Type

    Infrared

    Detects motion by sensing changes in infrared radiation (heat) emitted by humans or animals.

    Microwave

    Detects motion by emitting microwaves and measuring changes in the reflected radiation.

  • Range

    The range refers to the maximum distance in meters within which it can detect motion.

  • PET

    Motion sensors with this technology are designed to "ignore" the movement of small animals, such as dogs and cats, thus preventing false alarms.

Description

The Dahua ARD2231-W2(868)-B motion sensor combines passive infrared detection (PIR) and microwave detection (MW) for indoor and outdoor use. Its dual technology helps reduce false alarms, while PIR detection covers up to 12 m at a 90° angle. PET immunity allows pets weighing up to 18 kg and measuring less than 50 cm in height.

The sensor uses 24 GHz microwave detection based on the Doppler effect and offers 3 PIR and MW sensitivity settings. It includes bidirectional temperature compensation and two-way communication, anti-interference protection with frequency hopping and AES-128 encryption, a test mode, a low-battery warning, LED indicators, and an ON/OFF button. It features tamper protection and supports software updates via the cloud.
