When you attach the Ring Video Doorbell Pro from Ring to your existing hardwired doorbell, you are able to monitor your front door area using your mobile device. The Ring Doorbell Pro features 1920 x 1080 resolution for high-quality images, and it has built-in IR LEDs for use at night or in low-light conditions. The camera has a 160° field of view for a wide coverage area, and integrated 2-way audio allows you to listen and respond to those you are monitoring.
