Dr bell does not capture most movements even after delays

I wonder if my system is hacked, despite this 2 - factor authentication now added. I was parked in front of my own use, all scenes should've been captured. Pulling up, parking, me exiting my car, me walking toward porch where drbell is located. So out of these movements, at least 3 or so should be included in event history. Not a 1 appears in same. Have wedge put in, to angle it's placement better, just VERY SELECTIVE CAPTURING, as if it is being controlled to record only certain activity. Settings ore ok. Very odd and unreliable device and system. This has happened since 1st install, 2 yrs ago, in spite of repeat visuirts by Art, whose techs installed it.I posted this complaint at 12:56am on 4-6-2020, by the way. NOT ON 4-5-2020 AT 1035PM!!
