Amazon’s latest Alexa-enabled device is a home security camera that lets you keep a close eye on package deliveries. The online shopping giant has announced a new in-home delivery service for Prime members called Amazon Key that lets couriers unlock your front door and put your package safely inside your home. The service relies on a Amazon’s new Cloud Cam and compatible smart lock. The Cloud Cam captures 1080p resolution video, and boasts night vision, two-way audio, a wide viewing angle, and activity clips from the last 24 hours via the Amazon Cloud Cam app. You can purchase one camera, or get it bundled with a smart lock if you’re buying the Amazon Key in-home delivery bundle. The basic service is free with the option of paying a monthly fee for more features.
