The Ring Pro delivered very sharp 1080p video in testing. Daytime video was clean with rich colors, and night vision video was well lit with good contrast and remained sharp out to around 20 feet. There was noticeable barrel distortion around the edges, but people and objects appeared normal. Two-way audio was loud and clean, unlike the original Ring Doorbell which would become garbled on occasion.
2 - This kind of goes along with #2. You cannot access the doorbell with security software like Blue Iris,et.al. Now, I get that they want to sell you their Cloud service and I'm ok with $30 / year to have an off-site backup. But if you could link the doorbell into your security system you would have an actual video of everything in your possession and you could access it from any computer in the world. That would be REALLY handy for police investigations and any legal hassles that may come your way.
