Replaced my ring doorbell can with this and couldn't be happier. Better picture with AI detection that only tells me when people, pets, or cars are detected instead of wind blowing through the trees. The PoE or existing doorbell power options are great. My PoE power has battery backup and a wired connection means even with a WiFi jammer and a power outage I'm still covered. Documentation could be a little better (how to tell which side of the wedge goes out, if you can use PoE power and hardwire power at the same time, and how to setup locally without app or Internet if you do choose) but I was able to get everything working with a little trial and error.
