For anything, a wired system is much better than a wireless one. For security, the difference is even more pronounced.
Having said that, for a year and a half now, I have very good result with SkyBell HD WiFi Video Doorbell (make sure it's the "HD" version). I use the SkyBell for its audio capability (you can talk to the person at the door), in addition to my wired cameras.
I also have a WiFi Closeli camera. It loses WiFi connection much more often than the SkyBell.
With the SkyBell (vs Closeli and Ring), there's no monthly service charge you have to pay.
I know, it's not exactly what you're asking. But if I were to install a WiFi camera in my garage, I'd choose the SkyBell (I currently have a wired system).
