On A320 and A325 (A320G), there are two inputs and two outputs. The two cameras differ in the way these pins can be used.
A320 / A310:
- The state (high or low voltage) on an input pin is used to start an event in the camera, for instance set a flag in the image stream or trig an alarm activity.
- The state (high or low voltage) on an output pin is controlled by an activity in the camera, for instance by the result of an alarm detection
A315, A325 (A320G) & A615, A655sc:
- The state (high or low voltage) on an input pin is used to mark images for use by an application.
- The state (high or low voltage) on an output pin is controlled by an application.
