I have the BT smart baby monitor 8600 5” screen. I am looking to get a second camera, I can see that I can have multiple cameras on the smart app, however I cannot find any instruction on connect 2 cameras to 1 screen. Is this possible? I know it’s not a split screen, but can I flick between the 2 cameras on the screen? Or do they have to be connected/disconnect continuously to go between 2 cameras? Thanks
