Amazon’s Ring has decided that what your semi-detached really needs is its very own autonomous aerial sentry. Enter the Always Home Cam: an indoor drone designed to patrol pre-set flight paths, investigating disturbances before dutifully returning to its dock to recharge and physically tuck its camera away. It is the ultimate gadget for anyone who wants to bolster their home security while simultaneously feeling like they’ve been cast in a mid-budget sci-fi thriller.
