If you’ve been wanting to see who's at your door or just want to keep an eye on those after-Christmas package deliveries, now's the time to invest in a doorbell camera.

As of Dec. 24, you can get the Blink Video Doorbell system (which includes the Sync Module) for just $29.99 at Amazon. That's a 57% discount off its $69.99 list price and matches the record-low it first hit back in October.

You can choose to set it up wire-free using the included AA lithium batteries, which are rated to last up to two years, or hardwire it to your existing doorbell chime. It features head-to-toe HD video so you can actually see packages on the ground, infrared night vision, and two-way audio so you can talk to visitors through the app. It also works with Alexa, so you can get alerts on your Echo devices or even see a live view on an Echo Show whenever you'd like, just by asking.
