Description
The DHI-ARD324-W2(868) is a wireless magnetic contact with mounting for the Dahua alarm system, suitable for securing doors and windows. It has a reed contact, up to 40mm opening, 1 dry contact input, low battery warning, LED indicator and tamper protection. In addition, the contact can measure the temperature level with an accuracy of ±1°C in the range from -15°C to +65°C. In addition to the open and close detection, this model also has a tilt sensor and a shock sensor, making this model ideal for bedroom windows where you can set the alarm to night mode and still ventilate the room with tilting windows.
The DHI-ARD324-W2 communicates bidirectionally at distances up to 1200 m in open space, using wireless frequency 868 MHz, with protection by AES128 encryption and frequency hopping. The sturdy housing, made of high-quality PC + ABS material, allows use at temperatures between -10°C and +55°C, and is designed for indoor applications. It is powered by a CR123A battery with an autonomy of up to 5 years.
