How to configure 2N® IP Intercom
First of all you have to configure the switch, you chose for the control of the cameras. We chose Switch 4. Parameter "Switch mode" has to be set to "Bistable". This basically ensures the switching between cameras. You can set "Controlled Output" to "None" if you want to use the switch icon only for the camera switching. This ensures that once you tap on the switch icon in the app, only the cameras will be switched and no physical output will be triggered. Then you have to set "Switch-On Command" (and "Switch-Off Command" ( ) . These are commands sent when you tap in the app. The intercom sends a HTTP command to itself to control the cameras. Once it is received, then intercom operates with it in an automation function described in the second article below.
Now you have to create an automation function which will control the cameras switching. Camera switching is based on HTTP commands as mentioned above. The function also ensures, that once the call is terminated, camera is always switched back to the internal one.
