When someone knocks on your door in the evening and you're in for the night, it can definitely startle you. You didn't invite anyone over, you aren't expecting a package, and it's dark out. No way you're walking over to the door and opening it. What's the solution? Be prepared with a video doorbell.

Right now, you can get the wireless, battery-powered Google Nest Doorbell for its lowest price yet at Amazon. It's $119.99, which is $60 off its normal price of $179.99. That's a savings of 33%.

This wireless doorbell is simple to install without worrying about drilling holes or setting up any wiring. It works with any door. All you need to do is decide where to put it and connect to the accompanying app, and the device will do the rest. It gives you 24/7 live video access to the view outside your door, and allows for up to three hours of free event video history. Beyond that, you'll need to subscribe to a Nest Aware plan for up to 60 days of video to sift through.

You can see what's going on live outside at any time in HD video with HDR and night vision straight from your app. It also lets you talk to and listen to your visitors so you can screen those who come to call, even if you're far away from home. Alternatively, you can leave pre-recorded messages to communicate with anyone who comes by.

It's a dangerous world out there. If a video doorbell gives you a little peace of mind, then it's worth grabbing. You never know when you're going to need video footage of who's prowling around at night.
