This video doorbell was named The Best because it ranked the highest in every evaluation conducted by the Hammacher Schlemmer Institute. When the doorbell was pressed, it took only 7 seconds to display a live video image on a smartphone, while lesser units sometimes required up to a minute. Panelists also preferred its sharp 2K resolution and clear audio over inferior doorbells that showed choppy pictures or had poor sound quality. Rated as the easiest unit to set up, it easily connected to a Wi-Fi network with a free app that lets you see, hear, and speak with visitors from anywhere via your laptop, tablet, or smartphone. The doorbell has face and motion detection, infrared night vision, and stores footage on an in-home base with military-grade encryption. Works with Google Voice Assistant or Amazon Alexa. Charges via in-home base; base plugs into AC.
