By combining passive infrared (PIR) and active microwave technology, false alarms caused by environmental factors such as temperature fluctuations or air currents are drastically reduced. An alarm is sent only when both sensors detect movement simultaneously. The device communicates via 868 MHz and Wi-Fi for a stable connection to the AirShield Hub.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDual-tech detector: PIR + microwave — alarm only when both sensors detect movement simultaneously\u003c\/li\u003e\n\u003cli\u003eDrastically reduced risk of false alarms compared with standard PIR detectors\u003c\/li\u003e\n\u003cli\u003e868 MHz and Wi-Fi connectivity for a stable connection to the AirShield Hub\u003c\/li\u003e\n\u003cli\u003eInstant push notification in the event of an alarm via the Dahua DMSS app\u003c\/li\u003e\n\u003cli\u003eCompatible with Dahua AirShield alarm systems\u003c\/li\u003e\n\u003cli\u003eFault detection and communication encryption\u003c\/li\u003e\n\u003cli\u003eWireless — easy installation without cabling\u003c\/li\u003e\n\u003cli\u003eDimensions: 128 × 71 × 53 mm — black finish\u003c\/li\u003e\n\u003cli\u003eIndoor use\u003c\/li\u003e\n\u003cli\u003e3-year warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMotion detection in environments with a high risk of false alarms\u003c\/li\u003e\n\u003cli\u003eProfessional installations where reliability and a low risk of false alarms are essential\u003c\/li\u003e\n\u003cli\u003eRooms with fluctuating temperatures, air currents, or pets\u003c\/li\u003e\n\u003cli\u003eExpansion of existing Dahua AirShield installations\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Dahua","offers":[{"title":"Default Title","offer_id":57105859117380,"sku":"DHI-ARD2231-W2(868)-B","price":115.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0896\/8493\/4980\/files\/dahua-ard2231-w2868-airshield-draadloze-dual-tech-pirmicrogolf-bewegingsdetector-zwart.jpg?v=1786755875","url":"https:\/\/ipcam-live.myshopify.com\/en-nl\/products\/dhi-ard2231-w2868-b","provider":"IPcam-shop.nl","version":"1.0","type":"link"}
