Honeywell DT7435 Frequently Asked Questions

What Makes a Motion "Dual Tech"?
A "Dual Tech" motion sensor uses both passive infrared (PIR) technology and microwave technology to detect motion. Both the PIR and microwave sensors must activate in order for the device to trigger. This makes them great for reducing false alarms. Learn more about Dual Tech motion sensors.

Microwave vs. Passive Infrared Motion Detectors
Two of the most common methods for detecting motion are microwave sensing and passive infrared technology. These two methods are both highly effective in detecting motion, but they operate in completely different manners. Learn more about microwave vs. passive infrared motion detection.

How Does a Microwave Motion Detector Work?
A microwave motion detector constantly sends out microwave signals. These signals bounce off of objects to return to the sensor. If no motion is present, then the timing of these signals will be consistent. Motion will disrupt these signals and trigger an alarm. Learn more about these sensors.

What is a Microwave Motion Detector?
A motion that uses microwave technology will send out microwave signals to determine the structures in a room. The signals will bounce off the structures and return to the sensor with precise timing. A change in this timing means that motion is present. Learn more about microwave sensors.
