You leave the Camera on 1090p or 4k and press Auto Config within the Driver and sorts it all out like magic
We have 4 1080p and 3 4k Hikvision Cameras external - 4k Stream on the Touchscreen as a small colour band running across the Top - No Issue on iPhone or Ipad
We have two Internal Cameras (Hikvison) which only show a Snapshot - Not sure why -These are also 4k
All are IP cameras recording to a NVR
