Blue Iris - UI3 display camera when doorbell pressed?

I’ve recently setup a doorbell and am able to monitor the doorbell press within HA. I have the doorbell video stream going through to Blue Iris. The main security monitor displays the Blue Iris UI3 all cameras, what I’m trying to do is get the UI3 to display just the doorbell camera full screen when the doorbell is pressed.

Any idea on how I could achieve this?

I realise I could pull the video stream into HA and do it that way though the security camera monitor in the house isn’t running HA.

For more information the doorbell I got was the Hikvision DS-KV6113-WPE1, monitoring the doorbell press with rest platform - http://IP_ADDRESS/ISAPI/VideoIntercom/callStatus?format=json
