Amazon Key

Amazon Key, the e-commerce giant's in-home delivery

service that's off to a bumpy start, may soon get backup

from one of the hottest smart home startups around.

Fortunately for Amazon, that startup is now part of the

Family.

The e-commerce titan on Thursday said it has completed

its purchase of Ring, a maker of video doorbells and

security cameras, after revealing the deal in late February.

Now the work starts in earnest to figure out how to combine

forces, including potentially adding Ring into Key, according

to Dave Limp, head of Amazon's devices and services.

"As it relates to Key, that's obviously one that we'll look at

pretty closely," he said Tuesday. "I wouldn't want to make

any commitments at this point in time, but it's certainly one

that's on the list that we'll start thinking about."

Limp's comments, which were part of an interview that

included Ring CEO Jamie Siminoff, offer a hint as to how

Ring fits into Amazon's broader strategy for the smart

home. The deal comes as Amazon is working hard to

maintain its dominant position in the area, where its Echo

devices control 70 percent of the US smart speaker market.

Also, its Alexa voice assistant works with thousands of

gadgets, including Ring's products.

But with Google, Apple and Samsung all pushing into the

same business, Amazon is trying to keep its edge by

continually growing its portfolio of devices, from the Fire

TV stick to the Cloud Cam security camera to smart doorbells.
