The Honeywell DT8050A Dual Tec Motion Sensor is a great hardwired motion detector for virtually any home. This device offers an anti-masking feature to prevent others from obscuring the lens. As a a dual-tech sensor, both passive infrared (PIR) and microwave detection methods are provided.

In order for the DT8050A to activate, both the PIR and the microwave sensors must be triggered. The PIR sensor works by detecting the change in infrared energy that occurs when a person or object comes into the sensor's coverage area. The microwave sensor works by sending out microwave signals and recognizing how the signals return to the sensor as they bounce off of objects. By requiring both sensors to activate, the DT8050A works to prevent false alarms, while still responding when needed. A user can adjust the sensitivity of the PIR sensor by increasing or decreasing its pulse count. The signal range and strength of the microwave sensor can also be adjusted accordingly.

The maximum coverage area of the DT8050A is 53 feet by 72 feet, and this achieved by mounting the sensor from a recommended height. For best results, the sensor should be installed between 6'9" and 8'9" high, with the ideal height being 7'6". Another feature for the sensor is its integrated LED light that is used for testing and troubleshooting purposes. A zero-clearance bug guard is also included to prevent insects from tampering with the device. The fresnel lens provides uniform sensitivity optics to ensure that detection is consistent across the coverage area. The PIR sensor also uses dual slope temperature compensation so that it works properly in any ambient temperature.

Note: Honeywell offers the DT8050M, which is the same version as this sensor but with mirror optics.

The Honeywell DT8050A is a dual-tech motion sensor that features anti-masking to prevent others from disabling the sensor. It offers a wide coverage area of 72 feet by 53 feet, and it uses PIR and microwave technology to detect movement. Both the PIR and microwave sensors must be triggered for the device to activate. The wired sensor must connect with either a wired panel or a hardwired to wireless converter in order to be used. Overall, we think the Honeywell DT8050A is an excellent sensor, and we give it a 5 Star rating.

There are many aspects we appreciate about the Honeywell DT8050A. For one, using both microwave and PIR technology helps prevent false alarms. Even if one sensor is activated, no alarm will occur unless the other is activated. This ensures a reliable response during true motion events, while preventing any false alarms from occurring. We also like the large coverage area of the DT8050A. And the anti-masking is a great feature, as it alerts the system if someone applies a substance to the detection lens that could otherwise prevent the sensor from working properly. The DT8050A also features a bug guard to keep out any unwanted insects. And the fact that you can adjust the sensitivity for both the microwave and PIR sensors is a nice touch. And it has an LED light for walk testing and troubleshooting.

There are not many downsides for the Honeywell DT8050A. The sensor must be physically connected with the panel or a wired to wireless converter, and it will draw a small amount of power, so keep that in mind. But really the Honeywell DT8050 is great for anyone who needs a hardwired dual-tech motion sensors. It earns 5 Stars.

Good: Dual-Tech, Prevents False Alarms, Reliable, Anti-Masking, Bug Guard, Sensitivity Adjustments, LED Light

Bad: Must be Wired, Draws Power

Bottom Line: 5 Stars
