PIR sensors and dual technology detectors work on the principle of double knock – or in some cases triple knock - after threholds have been crossed and before an alarm is signalled. With double knock one sensing element within a...

Q: Is it worth using somewhat less sensitive dual detection technology to increase resistance to false alarms? A: It doesn’t necessarily follow that a dual technology sensor is less sensitive to a genuine intrusion than a PIR – the reduction...

They're the most common security sensing devices you can buy but too many installers still get it wrong when they're putting in PIRs. And just going for dual technology sensors instead of installing PIRs properly is poor practice. FOR many...
