## Products
- [Dual Technology Motion Detector](https://www.guardianssa.com/c/products/dual-technology-motion-detector): Fully secure homes and buildings of all sizes with the PowerG Dual Technology Motion Detector that combines advanced PIR detection algorithms with K-band microwave detection to dramatically reduce false alarm events even in harsh installations. The detector sends an alarm signal after both the PIR and the microwave sensors have detected an intruder, significantly reducing false alarms. Uniquely designed to continuously adjust its sensitivity according to the location temperature, the dual technology motion detector is able to detect an intruder even when the ambient temperature is close to that one of the human body.
