How does a dual tech PIR work?
A motion is “Dual Tech” if it uses both passive infrared (PIR) technology and microwave technology to detect the presence of motion. Both the device’s PIR sensor and its microwave sensor must be triggered in order for an alarm event to occur. A PIR sensor works by looking out for changes in infrared energy.
What is a dual technology detector?
The dual-technology detectors associates a passive infrared (PIR) sensor with a high-frequency microwave sensor with Doppler effect. The frequency differences between the signal transmitted and the signal received provide information about the moving objects in the detection area.
What is pulse count on a PIR?
The PIR detects motion in its detection pattern by measuring the infrared emission levels of objects that it sees. As a person moves across the detection pattern, the PIR registers one pulse as each finger of the detection pattern is crossed. The TMD-90 counts these pulses.
What is microwave sensor?
Microwave sensors, also known as Radar, RF or Doppler sensors, detect walking, running or crawling human targets in an outdoor environment. Microwave sensors generate an electromagnetic (RF) field between transmitter and receiver, creating an invisible volumetric detection zone.
What is microwave motion sensor?
What is a Microwave Motion Sensor? A microwave motion sensor uses electro-magnetic radiation. It emits waves which are then reflected back to the receiver. If there is an object moving in the room, these waves are going to be altered. The microwave detector is able to identify changes from moment to moment.
What are microwave detectors?
A microwave motion detector is a security sensor that uses a microwave radar to detect the presence of motion. This type of radar works by continuously sending out microwave signals. The signals should bounce off the objects in the room and return to the sensor with consistent timing.
Are microwave sensors better than PIR?
PIR sensors are neither objectively better or worse than microwave sensors. Both sensor types have their own advantages and are better for different spaces and tasks. Lights that feature PIR sensors are generally best for use as security lights.
What is a microwave detector called?
Microwave sensors, also known as Radar, RF or Doppler sensors, detect walking, running or crawling human targets in an outdoor environment.
