Bosch Blue Line Intrusion Motion Detector Tested

Author: Brian Rhodes, Published on Jan 03, 2017

False alarms from motion sensors are one of the most aggravating parts of intrusion detection.  

Bosch says their sensors are better, even claiming their premium Blue Line PIR series give no false alarms.

In this test, we bought the Blue Line Pet Immune Gen2 sensor through the paces. Criteria tested includes:

  • Angle of Detection
  • Range
  • Pet Immunity Function
  • Detection Reliability
