The short answer
Check whether new frames stop arriving or only one view stops updating. Compare stream load, competing sessions and a wired path using the same camera profile.
Work through the checks
Test one camera and one stream before opening a larger camera wall. Keep the camera settings unchanged while you establish whether the first live image is stable.
Close duplicate viewers and unused recorder previews during a controlled test. Some cameras limit simultaneous sessions; add each client back separately to find the constraint.
Compare with a wired connection where practical, keeping the stream profile unchanged. This separates Wi-Fi signal or contention problems from camera encoding and viewer behavior.
Observe CPU, GPU, memory and network use in Windows Task Manager with one view, then add views gradually. Record the point where playback begins to lag.
What to verify
Change one setting, then repeat the same short test after a controlled app or device restart. Record the error time and whether the problem recurs rather than treating a temporary recovery as a diagnosis.
Sources and scope
AeoCam is available for Windows. Camera settings below describe protocol preparation, not a certification of a particular camera or a promise of every feature in every app version. Check the installed build and the Microsoft Store listing for current availability.
Vendor documents describe the camera or protocol. No physical-camera compatibility test is claimed here. Menus and capabilities can change with model and firmware.
