Motion Detection Query

Is there a way to adjust the motion detection as one of my cameras doesn’t pick up motion unless very close? It’s currently 6ft above the ground and I’ve already tried setting up detection zones.

Did you take a look at the help page for the eufycam?
It has some useful tips on mounting. It’s important that the way people walk into the view is across (left-right and vice versa) rather than straight towards the camera. The camera will have a hard time picking it up as motion.
