DropZone

Your Ring camera checks the drone drop zone before the drone arrives. Ring sees the zone and Alexa tells you what is in the way (simulated Alexa+ add-on). With your yes, your devices help clear the spot: a smart pet door lets the dog in but not back out, yard lights come on at dusk so the camera can read the zone, and a sprinkler run is paused for the drop window (all simulated). The camera re-checks, and the drone carrier gets a HOLD signal before landing when the spot is not clear. The carrier never receives video.

Why

Drone delivery is moving from pilots to everyday use:

• Amazon's goal for Prime Air is 500 million packages a year by the end of the decade (Amazon), with nearly 500 US cities and towns planned by the end of 2026 (Amazon).
• Zipline passed 2 million deliveries in January 2026 (Zipline) and completes one every 20 to 30 seconds (CNBC).
• Walmart passed 1 million drone deliveries in May 2026 (Walmart); Wing and Walmart plan 270+ locations reaching 40M+ Americans (Wing).
• The FAA's BVLOS rule (Part 108) is under review and not yet final (Drone Authority).

Each delivery needs a clear patch of yard, and nobody checks that patch before the drone shows up:

• Amazon asks customers to keep "people, pets, vehicles, and objects taller than 5 feet … at least 10 feet away from the selected delivery point" (Amazon drone FAQ).
• If anyone runs through the zone, the drone aborts and the item goes by ground instead (CT Insider). A Phoenix customer's advice to others: "If your dogs are in the backyard, bring them in" (Business Insider).
• Packages have ended up in pools and ponds (The Verge, AZFamily).
• USPS recorded 5,246 dog attacks on its carriers in 2025 (USPS), and an estimated 104.3M packages were stolen in a year, about 250,000 a day (SafeWise). Where a package lands matters.
• Drop points are chosen remotely from maps, and the drone sees the spot for a few seconds from about 13 ft up (Prime Air technology).

A Ring camera has watched that same patch of ground for months. It knows the dog is out right now, that a patio umbrella appeared yesterday, and where the pool is. DropZone uses that knowledge before the drone arrives, at the point where the household can still do something about it.
