The Bosch Blue Line Gen2 Series of Motion Detectors use a combination of passive infrared (PIR) and microwave detection technologies with advanced signal processing. The pet-friendly (-WP) models generate alarms for human intruders without generating false a larms for pets. These small unobtrusive detectors are simple to install and do not need field adjustments.
The ceiling mount Bosch DS939 PIR Detector provides a 21m panoramic coverage pattern and can be used on ceilings as high as 7.6m. With three separate PIR sections that are fully adjustable, the DS939 provides coverage integrity at all mounting heights, plus the ability to customise the coverage for specific areas. The DS939 uses several patented processing techniques to provide excellent catch performance with freedom from false alarms.
