Ring app to your iOS and Android mobile devices to inform you of visitors. A cloud recording feature makes sure that you never miss any goings-on at home. The HD video is recorded and stored in the cloud, and can be previewed immediately using the Ring app.
The Ring also includes a two-way voice communication and a one-way video so that you can see who is at your doorstep. The app rings on your mobile device when a guest presses the doorbell. The app lets you get a preview of your guest, and you can choose whether you accept or decline the call. Not only that, the app enables you to access multiple Ring doorbells on a single smartphone.

The two-way voice communication works admirably, and the video provides you a decent, wide-angle look at your outdoor surroundings. Video and image quality is suitable for identifying guests and having brief conversations with them.
Summary

The Ring Wi-Fi Enabled Video Doorbell currently is regarded as a valuable security measure to homeowners who rely on not missing important guests and package deliveries. It’s a handy tool that provides you peace of mind when you’re away. The Ring developers have announced that they will update the doorbell’s motion detection feature. It will enable the device to monitor inactively front door activities, capture videos, and save them to a cloud for future reviews. The motion detection option will still alert you to someone’s presence even if your doorbell doesn’t ring. It will certainly add more value to the simple, and useful features of the Ring Doorbell and I consider it as the best video doorbell right now.
