Calling sequence

For ONVIF digital input function, the calling sequence of Genius Vision NVR can be summerized as follows:

  1. This sequence only applies when Event.Template (explained here) is set to ET01.
  2. Calls <device>GetDigitalInputs to obtain number of input and their tokens. If failed, NVR will try to call <ver10/deviceio>GetDigitalInputs.
  3. Engage event notification sequence.
