I am looking for a way to set up 4 video cameras and be able to view all of them on 1 screen at the same time at a slight delay (roughly 6-10 seconds). The footage doesn't need to be stored as this will be used for live feedback sports analysis.
I would ideally have a wireless set up but am unsure how to get this to work. I have tried using the camera on a phone through chromecast to a monitor which works great for a single camera but I am not sure of any way to use this in a split screen mode from multiple devices.
Any ideas on how I might get this to work? and what sort of cameras/ hardware would be required for this?
