Thanks to EL’s patented Motion Vector Analysis technology, the Arrow XL operates with remarkable agility in a 9-meter curtain across display windows, skylights, sliding doors, attic entrances and corridors. Arrow XL analyzes signal pulses, recognizing their direction and distinguishing between permitted motion (approach from inside the protected perimeter) and suspicious motion (approach from outside the curtain).
The detector provides an analysis of environmental conditions through the entire movement speed frequency spectrum, allowing focus on intruders and eliminating environmental factors of false alarms. The spectrum analysis is embedded in the VLSI based electronics of the detector assuring high reliability and trouble free operation. As the LC-104-PIMW-W is a combined technology (PIR & microwave) an alarm signal relay activation occurs only when signals from both sensors (PIR & MW) are present at the same time. The effective detection range is the range of which the patterns (PIR & MW) are intersected. The GAIN potentiometer adjustment changes the MW signal intensity so that the effective pattern will be scaled.
