One of our favorite video doorbells is 47 percent off in the run-up to Prime Day

The Ring Battery Doorbell Plus is top pick for battery-powered doorbells, offering sharp 1536p video with a head-to-toe view that makes it easy to spot packages on the porch floor other doorbells might miss. It’s also the most responsive video doorbell our reviewer has tested, pulling up live feeds in about half the time of others.

Beyond that, the doorbell supports radar-based motion detection, which allows for more accurate notifications compared to previous models. It also retains support for color night vision, pre-recorded Quick Replies, and two-way talk, and, for $4.99 a month, you also get bonus features like package and people alerts. And because it works with Amazon Alexa, you can pull up the live feed on an Echo Show or Fire TV with just your voice for free.
