Camera Speaker Output - Ganz ZN-AIBOX-STD/PRO User Manual

The relay's output type is two settings, ON/OFF, but the settings screen is configured to allow
you to select four different items. The definitions for each output type are as follows.
Output type
On for Duration
Off for Duration
ON
OFF
You'll notice that the right side of each output type describes its priority. Since there are a
limited number of relays, and many event action items can be assigned to them, this creates an
issue of control over the relay device.
※ Relay type control policy
1. If multiple relay actions are the same priority, the last one to occur takes control
2. If higher and lower priority actions are competing, the higher relay type takes control.
Higher priority alarms have a duration, so the last lower priority action takes control
after the time elapses.
3. Low-priority items have no duration, so they permanently change the default state of
the output until a new request is made by another event action.

2. Camera speaker Output

If IP camera connected to the ZN-AIBOX-STD/PRO supports audio output through speakers, you
can drive an event action to emit audio output.
Camera speaker output operates based on the protocols defined by the ONVIF Audio
Backchannel standard.
※ Preconditions
To run the Camera Speaker Output action, you must set the video stream to connect an
additional audio session for sound transmission.
