Camera recording way too many clips seconds apart

My wife and 3 yr old will be playing in the front yard and the camera will just repeatedly send a notification that it spotted someone. Regardless if anyone leaves the activity zone. My son is short so it doesnt recognize him as much as everyone else. And My wife will be sitting in a chair as he plays so I guess the camera isn’t recognizing anyone since there’s no movement with my wife sitting and my son being short and not recognized often. Another annoying thing is it will record for 6 seconds when a delivery driver walks up my driveway and then he will be out of activity zone for 2 seconds and then come back walking to his truck. So it will record 2 videos instead of 1.

But what setting should I be using? Optimal surveillance? Customized recording?? I feel like customized would be the best but I don’t know what settings to use for it…
