The electronic commerce company have launched an exclusive service for their Prime members in certain cities in the US, where you can unlock your door via an app and watch a video of your parcel being delivered.
Writing on the website, Amazon shared: "On delivery day, you'll receive a notification in the morning with a four hour delivery window for when the delivery driver will arrive at your home. Right before the driver arrives at your door, you will receive an 'Arriving Now' notification and you can optionally watch the delivery happening live. The driver will knock first and then request to unlock your door with their Amazon handheld scanner.
"Amazon verifies that the package belongs to the address and the driver is near the door, turns on Amazon Cloud Cam and unlocks your door. No special codes or keys are given to the driver. The driver will then place the package just inside your door and request to relock the door. Once the delivery is complete and your door is relocked, you'll get a final notification and can watch a video clip of the delivery."
To make it work, you need the Amazon Key In-Home Kit, which includes an Amazon Cloud Cam (Key Edition) and an Amazon Key-compatible smart lock.
The Key lock also allows you to open your doors for guests or professional service providers.
They added: "Amazon Key lets you grant access to the people you trust. Schedule permanent access for your family members or give temporary access to recurring visitors like dog walkers, house cleaners, or out-of-town guests. You'll be notified any time your guest locks or unlocks your door ...
"In the coming months, Amazon Key will provide customers with a convenient way to provide unattended access to professional service providers. This includes services from home cleaning experts Merry Maids and pet sitters and dog walkers from Rover.com, as well as over 1,200 services from Amazon Home Services."
The Amazon Key In-Home Kit retails for $249.99.
