Great article with lots of useful information. Very comprehensive comparison that really helps people make a wise decision based on their particular needs. FYI, I chose abode for my home security needs because it’s a proven shipping product and it integrates well with other systems. Although the camera quality might not be as good as others, it will suffice for my needs.
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
Update 1/24/16 - I have found a fantastic use for the Ring Doorbell and Chime. My mother-in-law, now in her 90s, lives by herself. She has become hard-of-hearing and often does not hear the doorbell. By installing the Ring on her door, she now is bothered much less (solicitors tend to recognize it and don't seem to like it) and when someone rings the bell, the Chime, placed by her favorite chair, gives her a better chance of hearing someone at the door.
