An anonymous reader shares a report: Rushing home to sign for a package can be a chore, and nothing craters a day like having a delivery stolen from your doorstep. The question Amazon asks with its new Key app and Cloud security camera: Are those annoyances enough to let a delivery person into your home, unattended, to drop off a box? The answer should present itself soon enough, at least in the 37 cities in which Amazon will launch its new in-home delivery service as of November 8. There, customers who purchase an Amazon Cloud Cam, own a compatible smart lock, and download the accompanying Amazon Key app can grant access for in-home deliveries -- and watch the drop-offs live, remotely. The system, exclusive for Prime members, costs $250 to get started, a price that includes both the camera and a smart lock from either Kwikset or Yale. (You can also buy the cameras individually for $120, with a slight discount applied for buying multiples.) And while Amazon has gone to some lengths to minimize the creepiness of a definitionally invasive service, it still forces potential enlistees to consider just what kind of trade-offs they're willing to make in the name of convenience. Amazon says that in-home delivery will be available for "tens of millions" of items, whether it's sent same-day, standard, or any shipping method in between. As for those safety measures: Amazon's doing what it can to ensure that strangers don't game its system.
