multiple cam apps connecting over RTSP, problem?

I have a few Eufy 2k indoor cams. I am looking to

  • use a QNAP NAS to run a DVR app,
  • run Blue Iris on a Windows server as backup,
  • plus use a tablet mounted on a wall as live monitor.

So if each camera is sending RTSP feeds to 3 apps at the same time, is there going to be any problem?

I am thinking the CPU or mem in the camera may have a problem? or the amount of network traffic 3x the average may have a problem for the cam?

Try it out and let us know how it goes. I don’t think any of us have tried or done this so its limitations are unknown
