Advanced Dual-Tech Motion Detector for False Alarm Prevention
The Dahua Dual-Tech Motion Detector ARD2235 is a wired motion detector combining PIR and microwave sensor technology with up to 12-meter detection distance and 90-degree horizontal coverage. This Dahua dual-tech motion detector features pet immunity up to 25kg, providing reliable detection while avoiding false alarms from household pets. Moreover, its dual-sensor verification eliminates false triggers from environmental factors, making it ideal for commercial and residential installations requiring professional-grade accuracy.
Dual-Technology for Superior Accuracy
This Dahua dual-tech motion detector combines passive infrared (PIR) and microwave sensing technologies for unmatched detection accuracy. Both sensors must confirm motion before triggering alarms, virtually eliminating false alarms caused by temperature fluctuations, air movement, or environmental changes. As a result, you receive alerts only for genuine intrusions, maintaining system credibility while reducing unnecessary notifications.
Enhanced Pet Immunity Up to 25kg
The ARD2235 features advanced pet immunity supporting pets up to 25kg weight, higher than standard detectors. This Dahua dual-tech motion detector distinguishes between human intruders and large household pets including medium-sized dogs. Consequently, you maintain reliable security without false alarms from pets moving through protected areas, perfect for homes and businesses with animals.
Wide Coverage with Wired Reliability
A key feature of the Dahua dual-tech motion detector is its 12-meter detection range and 90-degree horizontal coverage combined with wired connectivity. The extensive coverage monitors large spaces effectively while wired operation ensures continuous, maintenance-free performance without battery concerns. Therefore, it provides professional-grade motion detection for commercial buildings, warehouses, and permanent installations.
Professional Integration
The ARD2235 integrates seamlessly with Dahua alarm controllers including ARC2008C-V3 and ARC2016C-V3 models. The dual-tech verification provides commercial-grade reliability while pet immunity enables practical deployment in diverse environments.
