So my hard wired doorbell failed to notice a person walking from the road up to my door and coming in my front door. I woke up early in the morning to noise upstairs and my husband asking is someone in the house? The doorbell camera failed to notice someone who walked directly in front of the camera all the way from the road, across the front yard, up the walk, up the porch stairs and let themselves in the front door. At no time did the camera even notice although the person was in full view of the camera field for several minutes during their approach and directly in front of the camera during their entry in through the locked front door. Thanks for nothing. I do not feel secure in any way. There is no reasonable explanation for such a gross failure.
