Dahua AirShield Wireless Dual-Tech Motion Detector ARD2231-W2(868)
The Dahua ARD2231-W2(868) stands at the forefront of indoor protection. This detector features Dual-Tech sensing, combining Passive Infrared (PIR) with 24GHz Microwave technology to validate human movement with extreme precision and eliminate thermal false alarms.
Despite its powerful radar detection, it features an optimized power management system with a maximum consumption of only 615 mW. This allows the CR123A battery to last up to 3 years, even with 10 daily triggers. It also includes pet immunity up to 18kg and digital temperature compensation, ensuring a reliable 12-meter range in any climate. Using AirShield technology at 868MHz with frequency hopping and AES128 encryption, it remains secure against jamming and interference.
