Dual-technology sensors

« Back to Glossary Index

Dual-technology sensors are a type of burglar alarm technology that combines two different types of sensors to provide a more accurate and reliable detection system. These sensors typically use both microwave and infrared technology to detect movement and changes in the environment. The microwave sensor emits a high-frequency signal that bounces off objects and returns to the sensor, while the infrared sensor detects changes in heat signatures. By combining these two technologies, dual-technology sensors can reduce false alarms and provide more accurate detection of intruders.

In the commercial and residential burglar alarm industry, dual-technology sensors are becoming increasingly popular due to their reliability and accuracy. These sensors are often used in high-security areas such as banks, government buildings, and other sensitive locations where false alarms can be costly and disruptive. Dual-technology sensors can also be used in residential settings to provide an extra layer of security and peace of mind for homeowners.

1. What are dual-technology sensors in burglar alarms?

Dual-technology sensors are a type of sensor used in burglar alarms that combine two different technologies to detect motion. These sensors typically use both passive infrared (PIR) and microwave technology to reduce false alarms and increase accuracy.

2. How do dual-technology sensors work in burglar alarms?

Dual-technology sensors work by using both PIR and microwave technology to detect motion. PIR sensors detect changes in temperature, while microwave sensors emit low-power microwaves that bounce off objects and detect movement. When both sensors detect motion, the alarm is triggered.

3. Are dual-technology sensors more effective than single-technology sensors in burglar alarms?

Yes, dual-technology sensors are generally more effective than single-technology sensors in burglar alarms. By combining two different technologies, dual-technology sensors can reduce false alarms caused by environmental factors such as pets or moving objects like curtains. They also provide a higher level of accuracy in detecting actual intruders.
