When I get a motion alert, the default setting starts the live video, but 99% of the time the event that triggered the alert has moved. Was it something moving left past the camera? Moving right? I dont' know, and I have to wait until the video stops recording and I can review the motion alert from the beginning.
Instead, you should have an option where when an alert is responded to on my phone, it takes me to the beginning of the recorded video. Then I can see what caused the alert and if it's worth pursuing. And if it's someone who went to the right, I know to look on that side of the house.
Obviously ring the doorebell is a different situation; I'm just talking about alerts.
