The online megaretailer announces some new additions to the lineup of battery-powered Blink outdoor cameras, as well as a new Stick-Up Cam from Ring. The Blink Outdoor 4 is getting a new battery pack accessory this year, and a larger version with a built-in floodlight is on its way.Amazon's annual September showcase of new devices and services on Wednesday featured the usual mix of Echo, Eero and Fire TV gadgets, but there were also a couple of new cameras and accessories for the Blink and Ring lineups making their debut.First, on the Blink side of things, comes a new $160 Blink Outdoor 4 Floodlight Camera with motion-activated security lighting, as well as a new battery extension pack for the existing Blink Outdoor 4 standalone cameras. That battery pack promises to extend the camera's battery life by up to four years for an upfront cost of $30. Both devices are available for preorder starting today and expected to ship later this year.Beyond that, Amazon also teased a new Blink Sync Module Pro that's slated for release next year at a price of $50. Add it to your setup, and it promises to extend the wireless range of your outdoor cameras significantly further than Wi-Fi, which might be useful if you have an especially large yard or property to keep an eye on.The Ring Stick-Up Cam Pro promises better sound quality and improved motion detection.On the Ring side of things, Amazon made sure to tout the arrival of the new indoor/outdoor Ring Stick-Up Cam Pro, available for preorder today at $180. The new wireless camera promises better audio from an improved array of mics, as well as smarter motion detection with refined alerts that only notify you when a person is detected within a specified area. You'll also be able to switch to a bird's-eye view of your property, with any detected paths of motion plotted out for you.Hardware aside, Amazon also noted that new, Ring-specific Alexa routines are on their way to the Alexa app. Presets include routines that turn your lights on whenever your Ring Doorbell is rung, or whenever your Ring Alarm security system is disarmed. Alexa users can look for those features via software update later this fall. Security Cameras Security Services
