I set and reset my doorbell and activity zone and sensitivity at Max for all motion but my door bell does not pickup any motion whatsoever . I am very frustrated . When setting up the doorbell keeps signaling me that there is a human detected but after I install the doorbell outside , this stopped detecting motion no matter what I do. I have deleted and reinstalled both chime and doorbell a few times and reset video, detection and activity zones etc but there is no change . help! Or I probably send this doorbell back ,only have it for a week.
