SAN FRANCISCO, Sept 30 (Reuters) - Amazon ( AMZN ) on

Tuesday unveiled a refreshed lineup of devices optimized for

home security and its new artificial intelligence-infused Alexa+

voice assistant.

At an event in New York, Amazon ( AMZN ) showed off Echo speakers, Fire

TV streaming devices, a new Kindle reader and improved Ring and

Blink cameras, which will be available later this year.

Amazon ( AMZN ) is trying to drive interest in the new Alexa, after

investing billions of dollars and years updating it with AI for

better personalization and a more conversational tone, with the

aim of turning the money-losing service profitable.

The Seattle firm said its new Echos, including smaller Dots

and Show devices with screens that range from $99 to $219, will

be enabled to work with Alexa+ and feature new silicon chips for

faster processing.

The new Blink cameras have a higher resolution for better

monitoring inside and outside one's home, while the improved

cameras in its Ring devices also offer facial recognition to

help ward off unwanted visitors.

The new Ring cameras will also be enabled with Alexa+,

allowing the devices through the use of AI to help make

decisions like whether a visitor is delivering a package or

casing someone's house for intrusion. They will be priced from

$60 to $350 depending on their utility and camera quality.

"It's about knowing immediately whether your visitor is someone

you know or someone you've never seen before," said Jamie

Siminoff, the founder of the world's first Wi-Fi video doorbell,

whom Amazon ( AMZN ) brought back to the company as head of Ring earlier

this year after two years.

Siminoff also showed a separate feature used to help Ring users

identify lost pet dogs in their neighborhoods by notifying other

community members who have the device. The feature, available in

November, is currently unavailable for other animals.

"We're turning individual concerns into community actions,"

he said.

Panos Panay, Amazon's ( AMZN ) device chief, demonstrated Amazon's ( AMZN )

new Kindle Scribe, a $630 tablet that allows for digital writing

with a stylus, and which features a color screen for the first

time.

"It just feels like you're writing on paper," said Panay.

New improved screen-quality Fire TV television sets,

ranging from $160 to $480, and a $40 streaming stick offer new

Alexa+-enabled features, like asking the voice assistant to find

and cue up a particular scene in a movie and to get more detail

on particular actors.
