Not detecting motion and quits recording while motion is still happening

I just bought the eufy 2 cams and had them installed for a couple of weeks. They seem to Not detect motion and quit recording while motion is still happening. Seems worthless. They dont capture motion until almost in front of camera. The one of two cameras only records 5 seconds every time. I have contacted them about it and they are sending a new one…but since figuring out how crappy motiom detection is, i might return and do a diff brand. And then the other day, the cameras stopped recording motion. I tested snd nothing registered. I did a reset and it started working again, but i read on here it happens to a lot of people for years, so the company has not yet solved that.
