2.3 Activate an output port
This example describes how to set up AXIS P8221 to activate an output port on another Axis network
video product, in this case AXIS Q7401 Video Encoder.
To accomplish this, a triggered event is set up in AXIS P8221. The event is triggered by a
signal from the AXIS P8221 Input port 1. When the event is triggered, AXIS P8221 sends an
HTTP notification to AXIS Q7401. The HTTP notification is a VAPIX command instructing
AXIS Q7401 to activate the Output port.
