It's now clear what the Blink team has been up to since Amazon acquired it in 2017 -- namely, a much-improved version of their core security camera. The newly-unveiled Blink XT2 looks similar on the outside, but packs several upgrades that include a dramatic improvement to battery life. The outdoor-capable camera lasts for two years of motion-activated use on a pair of AA lithium batteries. You'll also get two-way talk to ward off intruders, and refined motion detection that lets you define "micro-activity zones" to minimize the chance of false alerts. When recording video, Amazon says the XT2 will last twice as long as the previous model.
