Floodlight cameras

I’ve recently had a warranty replacement for a floodlight camera.
The problem, it’s doing the same thing the old one did.
A motion event is triggered, the camera starts recording, then freezes during part or all of the event with the sound still recording.
The record is useless, as whatever happened during the frozen video is lost.

if 2 seperate cameras are having same issue doubt its the camera. sure its not connection issue? wifi?
