False Alarms Got You Down? Exploring the PIR Tech Options

PIR detectors are motion sensors that detect movement by sensing changes in heat. They work by measuring the infrared light emitted by objects within their range. When something warm, like a person or animal, moves into the sensor's zone, it triggers an alert.

 

1. PIR Detector (Standard)

PIR detectors, which sense motion via infrared heat, are prone to false alarms. This happens because they detect any warm-blooded movement, including pets. Even a cat walking through a room can trigger an alarm despite posing no real threat. Additionally, sudden temperature fluctuations, such as a burst of hot air, can also mistakenly activate the detector. 

 

2. PIR Blue Line Detector

Blue-line detectors represent an advancement over standard PIR detectors. They boast enhanced sensitivity levels that can be adjusted to suit specific environments. Moreover, many blue-line models incorporate pet-immunity features, effectively filtering out signals from pets and minimising false alarms. This technology prioritises human detection, offering a more reliable and user-friendly security solution. A prime example of a blue-line detector incorporating these features is the Bosch Blue Line Gen2 TriTech ISC-BDL2-W12G.

 

3. PIR Dual-Tech Detector

PIR Dual-Tech Detectors employ a sophisticated approach to motion detection by integrating both infrared and microwave sensors. This dual-sensor system enhances accuracy and significantly reduces the likelihood of false alarms. Furthermore, these detectors are equipped with robust anti-electromagnetic and radio frequency interference capabilities, ensuring consistent and reliable performance across diverse environments, even in locations with potential signal interference. A prime example of a PIR product showcasing this advanced technology is the Hikvision Wireless Dual-Tech Detector DS-PDD12P-EG2-WB.

 

4. PIR Tri-Tech Detector

PIR Tri-Tech Detectors are specifically engineered for commercial applications, prioritising reliable motion detection while minimising false alarms. These advanced detectors integrate passive infrared (PIR) technology with microwave Doppler radar, utilising sophisticated signal processing for exceptional accuracy.
Designed with installers in mind, Tri-Tech detectors incorporate features like integrated, selectable end-of-line resistors, a self-locking enclosure with a built-in bubble level, and a removable lift gate-style terminal strip. These features streamline installation, making it up to 45% faster, easier, and more dependable. The Bosch Blue Line Gen2 TriTech Pet Proof ISC-BDL2-WP12G serves as an excellent example of a PIR product that embodies this Tri-Tech technology.

 

5. PIR Quad-Tech Detector

PIR Quad-Tech Detectors employ a unique approach by incorporating two independent sensors within a single unit, effectively functioning as two separate PIR detectors. Each sensor analyses the motion signal independently, and both must be triggered to generate an alarm. This dual-sensor system significantly enhances false alarm immunity by effectively filtering out spurious signals, such as noise spikes and disturbances caused by small animals.
Quad-Tech Detectors also demonstrate superior motion detection capabilities compared to standard PIRs or dual-technology detectors. They are particularly well-suited for challenging installation environments, such as scenarios where direct line-of-sight with the intruder may be obstructed or where intruders can quickly evade traditional pattern detection methods. The Bosch Blue Line Gen2 Quad ISC-BPQ2-W12 exemplifies this advanced Quad-Tech technology.
