What is a dual technology motion sensors?
Summary of the Article: Dual Technology Motion Sensors
1. What does a dual technology detector use?
Dual-technology sensors, also known as dual-tech detectors, combine passive infrared (PIR) technology, which detects heat coming from warm bodies, and microwave technology, which detects motion.
2. What is dual tech technology?
Sensors with dual occupancy detection technologies are commonly used for lighting control in spaces where motion is limited or where line of sight is obstructed. Referred to as “dual tech,” these sensors utilize Passive Infrared (PIR) technology for detection of occupant motion wherever line of sight is available.
3. How do dual technology occupancy sensors work?
Dual-technology sensors use PIR sensors together with another sensor technology, ultrasonic (active) or microphonic (passive). Dual-technology sensors activate lights only when both technologies detect the presence of occupants. They can give a higher likelihood of “false off” conditions.
4. What are the 2 types of motion sensor?
Ultrasonic motion sensors measure the reflections off of moving objects via pulses of ultrasonic waves. Vibration motion sensors detect small vibrations that people cause when they move through a room.
5. How is a dual sensor detector different?
Photoelectric alarms are generally more responsive to smoke from a slow, smoldering fire. Whereas ionization alarms are best at detecting smoke from a fast, flaming fire. Dual sensor smoke alarms use both ionization and photoelectric technologies in one alarm.
6. What 2 types of detectors should you have in your house?
Smoke and carbon monoxide detectors are two of the most important safety devices in your home. Bottom line, you need both smoke detectors AND carbon monoxide detectors to keep you and your family safe.
7. What is the difference between motion sensor and occupancy sensor?
Occupancy sensors differ from motion sensors in that they don’t require significant motion to work. Their purpose is not to detect motion but to detect whether people are present, even if they’re not moving around. Many occupancy sensors will use a combination of sensors and various technologies.
8. What’s the difference between PIR and microwave sensors?
Both are used as occupancy sensors, but their principles of working are different. Microwave sensors are active sensors as they emit microwave signals for detection. PIR sensors are passive sensors as they sense infrared signals emitted by various objects, including the human body.
9. What is the difference between single and dual motion sensors?
A dual-tech motion sensor detects movement using both passive infrared (PIR) and microwave sensors. It will only activate if both sensors are triggered. A traditional motion sensor detects movement using only a PIR sensor. A traditional motion sensor may also be called a PIR motion sensor.

What is the difference between motion sensor and occupancy sensor
Occupancy sensors differ from motion sensors in that they don't require significant motion in order to work. Their purpose is not to detect motion, but to detect whether people are present, even if they're not moving around. Many occupancy sensors will use a combination of sensors and various technologies.

What are the different types of motion sensor technology
There are three types of motion sensors that are used frequently: Passive Infrared (PIR), Microwave, and Dual Tech/Hybrid.
How do I block my neighbors motion sensor
Put Objects to Confuse Cameras
This feature can help the owners have footage recorded every time you or your family move around. In order to prevent your neighbor from using cameras with motion detection, set up or install moving objects in or around your house like flags or windmills that move whenever there's wind.
How do you tell if a smoke detector is a hidden camera
You can turn off the lights in the room and place your mobile camera over the smoke detector. If you come across any infrared lights on the screen, this could be because of the hidden camera. If there is a camera in the smoke detector, the light you will detect will either be a white colored light or a purple one.
What sensors do I need for home security

What are the different types of detector sensor
Seven of the most common types will be discussed below, along with a brief description of their operation, advantages and constraints.Electro-Mechanical. The most basic sensor is an electromechanical limit switch.Pneumatic.Magnetic.Inductive.Capacitive.Photoelectric.Ultrasonic.
What is dual motion sensor vs single motion sensor
A dual-tech motion sensor detects movement using both passive infrared (PIR) and microwave sensors. It will only activate if both sensors are triggered. A traditional motion sensor detects movement using only a PIR sensor. A traditional motion sensor may also be called a PIR motion sensor.
What are the three 3 types occupant detection system sensors
The three most common are PIR sensors (or passive infrared sensors), which detect heat energy, ultrasonic sensors, which emit high-frequency sound waves and measure how those sounds are returned, and time of flight sensors, which do the same thing but with infrared light.
Is a PIR sensor better than a motion sensor
Residential use; winner is PIR
PIR-sensing lights are often the best choice for outdoor security lighting. Because they only detect movement from live objects, they are less likely to cause false alarms.
What are the disadvantages of PIR sensors
Drawbacks or disadvantages of PIR sensor
➨They have lower sensitivity and less coverage compare to microwave sensors. ➨It does not operate greater than 35 degree C. ➨It works effectively in LOS (Line of Sight) and will have problems in the corner regions. ➨It is insensitive to very slow motion of the objects.
Which motion sensor is better
PIR sensors are the best option for security lights because they're cheap and effective.

What can block a motion sensor
A simple silicone spray will blind the sensor, and is invisible to the naked eye. It leaves a trace, but it might not be discovered until much later, if at all. Alternatively, you could place glass in front of the sensor when it was off, which would do the same thing.
