According to my postman even if a signature was required I'd have to prove it wasn't mine or that someone signed for me that wasn't me. A video door bell is the best way to prove a package was not delivered at the time stated or that a delivery was made at all. Still a big hassle to prove with the delivery company but the video doorbell is a deterrent. This is the second time of no delivery in a few months. Both times a speedy refund was given.
