Wireless dual PIR and MW detector 868 MHz DAHUA ARD2231-W2(868)
zł275.52
Tax included
The ARD2231-W2(868) wireless motion detector is an advanced device designed to detect intruders in a protected indoor space. By using dual detection technology, combining passive infrared (PIR) and microwave (MW), the detector is characterized by exceptionally high resistance to false alarms, making it an ideal solution for demanding security systems. The device features pet immunity for animals weighing up to 18 kg and up to 50 cm in height, which allows for effective protection of rooms where small pets are present, without the risk of triggering unwanted alarm signals.
The detector is powered by a CR123A lithium battery, which ensures years of maintenance-free system operation, matching the reliability of traditional wired solutions. Two-way communication and AES-128 data encryption guarantee a high level of radio transmission security. The device also offers advanced features such as adjustable detection sensitivity, anti-jamming protection through frequency hopping, and the ability to update firmware via the cloud. The robust construction and well-thought-out electronics make it a reliable component of a modern Dahua alarm system.

Software and system features
The device works with the Dahua wireless alarm system, offering full integration with the alarm control panel. The detector software supports advanced digital signal analysis algorithms that process data from the PIR sensor and microwave module in real time. As a result, the system effectively distinguishes an intruder's movement from environmental interference. The user can remotely configure detector parameters, such as detection sensitivity, via a mobile application or the control panel interface. The system also supports remote firmware updates (OTA), which allows for easy implementation of fixes and new features without the need for physical access to the device. Communication with the control panel is fully encrypted with the AES-128 protocol, which prevents interception or manipulation of the alarm signal. Additionally, the detector has a built-in test mode, making it easier for the installer to precisely set the range and detection angle during installation.
