The parent unit gives the option to view more than one camera in a Loop or two cameras simultaneously with the Split Screen feature.

Option #1 - Camera Loop: This option will display images from different registered cameras in a loop in sequence, beginning with camera one, then camera two, etc.

Option #2 - Split Screen: This option allows you to view two selected cameras at the same time.

You can view two cameras at the same time with the Split-screen feature. The LEFT side will show the current camera selected, and the RIGHT side will show the next available camera.

The LEFT screen’s audio will play on the Parent Unit when using the Split Screen feature. The right-side camera will show the sound detection icon but will not transmit audio.

If there is no sound from the left camera and the right one does, then the audio of the RIGHT camera will play as normal.

Please note that the VOX feature does not work in the loop mode and it only works in Split Screen mode at the moment. 

The speaker icon only indicates the priority of playing audio from any camera and not for sound detection notification.
