The VID-W03L040 is an externally rated PIR designed for accurate and reliable outdoor perimeter protection irrespective of weather conditions. A curtain detection pattern of 3m wide at a range of 40m achieves the best accuracy available on the market. Adaptive Threshold Discrimination technology reduces the number of nuisance alarms caused by vegetation, small animals and sudden environmental changes. This works by continually averaging background noise and adjusting the alarm threshold.
