The current generation of Wi-Fi video doorbells all runinto the same thing: your local architecture will make a huge difference in how well you like it. So some people will like it a lot (usually in the four-star range), and some people will say it just never works.
In particular, if there is a glass window, not tinted, near your front door, these doorbells will probably work much better for you. It’s just a matter of signal strength.
There are a few differences between ring and Skybell. Motion detection at the short range, within 5 feet, appears to work a little better on ring. Skybell works better where it’s very very cold, with ring going down to -5° F and Skybell going down to -40. Skybell has an “on demand” feature which lets you tune into the video feed whenever you want. Ring has more of an intercom model and you may miss the opportunity to view the video when someone rings the doorbell and then not be able to restart it. Ring can be battery operated, Skybell cannot. Skybell’s mounting design is a little more waterproof, so you may need to do some additional caulking with ring.
But the most significant thing seems to be local Wi-Fi strength, and that would affect both devices the same.
It’s also important to note that both devices work only on 2.4 Wi-Fi, not the 5.0 band, which also means you must have your phone/tableton the 2.4 band in order to sync them.
A lot of people add a Wi-Fi booster in order to improve the video from the doorbell, but doing so can then interfere with nearby zigbee devices.
So Many people have either skybell or ring and like it better than not having it but there are also still a lot of returns on both devices. It just depends on the exact set up at your house.
