What type of sensor utilizes both microwave and infrared technology?

The type of sensor that utilizes both microwave and infrared technology is known as a dual tech motion sensor. These sensors combine two different technologies to enhance their detection capabilities. The infrared component is sensitive to changes in heat, detecting body movement based on temperature differences, while the microwave component emits microwave signals that bounce off objects and detect movement based on changes in the return signal. By integrating both technologies, dual tech motion sensors can significantly reduce false alarms that may occur if only one technology were used, as they require confirmation from both sensors before triggering an alarm. This dual functionality makes them particularly effective in environments where reliable motion detection is critical.
