Here 's an odd one. My neighbor asked if I had footage from a package that was marked "delivered" at 2:09 pm 4/30/18 but he was home at the time, heard nothing, and could not find it. I see the OnTrack truck stopped in front of his house at that time, and I see a package came out of it, but if the driver had walked up to his door he should be visible through the van windshield, going up the path . It seems to me he did not approach the door, but simply replaced the package on the passenger side seat. My neighbor said he complained to Amazon, and the original package (not a replacement) was in fact delivered at the same time on the following day. So it all came out OK, but what exactly happened here? (The camera is an old Hikvision dome at 4 fps, not great but still somewhat useful.)
