Optimal Sub-Stream settings for Hik-Connect push playback (Bitrate/FPS/Resolution)?

Having issues with Hik-Connect push notifications: the alerts come through just fine, but video clips fail to load properly on the client’s iPhone — they either freeze on the first frame, keep spinning, or throw a decoding error.
Setup:
  • IP Camera: DS-2CD2T46G2H-4I (AcuSense G2, 4MP)
  • NVR: iDS-7204HQHI-M1/E (Hybrid AcuSense DVR)
  • 1x IP camera + 2x analog cams
  • Client is on a 4G router, no wired internet

I’m not entirely sure what’s causing the problem.
Could be a combination of iPhone + weak internet, or maybe I’ve configured the sub-stream with too high a bitrate for mobile playback.

What would you reccomend for this camera? What bitrate, what FPS, what resolution and should I apply these only to sub stream?

My thinking is that optimizing the sub-stream might help push video notifications load faster and more reliably on Hik-Connect (especially on iPhone over mobile data).

One user mentioned that maybe it could help if I put the IP camera as a standalone device on Hik-Connect app. Any, literally any advice is appreciated. Thanks.
