The Ring Battery Doorbell Plus is once again matching its July Prime Day low.

With Halloween and Amazon’s fall Prime Day just around the corner, now’s a great time to grab a video doorbell. They make it easy to watch over trick-or-treaters and keep tabs on Prime Day deliveries and right now, one of our favorites — the Ring Battery Doorbell Plus — is on sale for $79.99 ($70 off) at Amazon and Best Buy, which is its best price to date.

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.
