Because of covid most delivery companies have waived the signature requirement. That's not your fault. Delivery companies use many temporary workers who are over worked and under trained. Insurance with USPS is almost impossible to get a claim reimbursed.

Many deliveries are improperly entered as delivered. USPS won't even let you open a complaint until the item is 21 days past the estimated delivery date. The shipper does have more power to expedite the complaint because they have agreements with delivery companies to get discounts on shipping.

I have Wyze cameras and they are junk. Get a Nest, Ring or other name brand cameras and the image quality and user interfaces are superior to Wyze.
