"5D" is the next generation of Aritech signal processing. It builds on the current strengths of 4D, but adds an intelligent differentiation between fast and slow moving signals.
When a slow thermal source is detected, the signal processing switches automatically to the 5D mode and executes additional pattern recognition to distinct this signal from a slow walking person. If the signal fits, it must be an intruder and an alarm is generated. If there is no fit, the signal is ignored, which ensures signals such as moving reflection of sunlight are filtered out.
The result is a unique combination of high sensitivity detection with high false alarm immunity without the need for manual sensitivity adjustment.
