Dual-technology motion detector
A dual-technology motion detector is a type of sensor used in burglar alarm systems that combines two different technologies to detect movement. These technologies typically include passive infrared (PIR) and microwave sensors. The PIR sensor detects changes in temperature, such as the heat emitted by a person or animal, while the microwave sensor emits low-power microwaves that bounce off objects and detect movement. By combining these two technologies, the dual-technology motion detector can provide a more accurate and reliable detection of movement, reducing the likelihood of false alarms.
In the commercial and residential burglar alarm industry, dual-technology motion detectors are commonly used in areas where false alarms are a concern, such as in homes with pets or in areas with high levels of environmental movement, such as near windows or air conditioning units. They are also commonly used in outdoor areas, such as parking lots or loading docks, where traditional PIR sensors may be triggered by environmental factors such as wind or rain.
CGSmith, a business and residential security system installation and monitoring company based out of the Milwaukee WI area, understands the importance of reliable and accurate motion detection in burglar alarm systems. By utilizing dual-technology motion detectors in their installations, they are able to provide their customers with a higher level of security and peace of mind.

A dual-technology motion detector is a type of burglar alarm sensor that combines two different technologies to detect movement. Typically, it uses both passive infrared (PIR) and microwave sensors to detect changes in heat and movement in a given area. This combination of technologies helps to reduce false alarms and increase the accuracy of the sensor.
A dual-technology motion detector works by using both PIR and microwave sensors to detect movement. The PIR sensor detects changes in heat, while the microwave sensor detects movement by emitting microwave signals and measuring the reflection of those signals. When both sensors detect movement, the alarm is triggered. This combination of technologies helps to reduce false alarms caused by environmental factors such as pets or moving objects.
The main benefit of using a dual-technology motion detector is that it reduces false alarms and increases the accuracy of the sensor. By combining two different technologies, it can detect movement more accurately and distinguish between human movement and other environmental factors. This makes it a more reliable and effective burglar alarm sensor. Additionally, some dual-technology motion detectors can be programmed to ignore certain types of movement, such as pets, which further reduces the risk of false alarms.
