Trigger Mode:
ZKTeco is normally in an idle state. When a trigger command is received, it performs
a variable number of captures, depending on configuration, and returns a result. Results from
different triggering events are independent of one another, that is, if the same vehicle, is still
present on a second trigger command, the same license plate will be returned a second time. On
every trigger, it performs captures until the number exceeds NCaptures, or the time exceeds
Timeout.
