Thanks to Amazon Prime Day, the second-generation Ring Video Doorbell is half off and on sale for only 50. That's the best price we've seen on the 1080p video doorbell that includes motion detection and night vision. The device also supports two-way audio, so you can communicate with anyone approaching your home. This Ring model is battery-powered, so you won't need to worry about a complicated wired setup. All you have to do is mount it and connect it to your Wi-Fi network through the Ring app.
