Continuous recording and IntrusionTrace.h
IntrusionTrace.h with adjustable sensitivity and definable detection areas can be used for recording according
to the same principles ruling continuous recording with external detectors. It is important to consider the state
of the respective control input Open or Closed. In addition, the recording interval and the number of frames to
be recorded can be defined for each detected motion. To calculate recording time, multiply interval by number
of frames.
