DHI-ARD323-W2(868)
Dahua Wireless Door and Window Magnetic Contact Detector operating at 868MHz. Uses a reed switch sensor to detect door or window opening events, triggering an alarm when the gap between sensor and magnet exceeds the detection threshold (up to 40mm movement distance). Features two-way communication with AES128 encryption, frequency hopping for interference resistance, built-in temperature monitoring, 1-channel dry contact input, and cloud-based remote firmware updates via the DMSS app. Powered by a single CR123A battery rated for up to 4 years (NO input type).
