It seems larger than the Ring doorbell.
It is hard to say for sure, but other images I found online seem to indicate that it is pretty similar in size to nest/ring (measuring the proportions show they are extremely close), it just looks more boxy, while the others look a lot more fancy.
One image I found also included a shot of the backside of the Wyze doorknob and showed the screwhead that comes with it. (you can also get good closeup pictures of lens size online and assuming it is the same lens as the other cameras, you could use that as a measurement comparison to figure out the exact size). I just used the screwheads so far. Now granted screwheads can vary a little in size, but using the screwhead as a base of measurement:
The Wyze video doorbell is approximately 6.88 screwheads (6.88sh’s) in width by 13sh’s in height
a) Again we don’t know the EXACT measurement of the screwhead, so it is hard to guess the exact dimensions from that.
6.88sh’s X 13sh’s means the height is about 1.89 times the width.
a) By comparison, the Ring Doorbell = 2.43" X 4.98" with height 2.05 times the width.
If I didn’t do the math wrong (hey, sorry, it’s been a while!), and assuming the Wyze doorbell is either the same width or the same height as the Ring doorbell, then Wyze’s system is quite possibly either 8.5% shorter than Ring (Awesome!), or 8.5% wider.
a) 8.5% shorter would make it: 2.43" X 4.56"
b) 8.5% wider would make it: 2.62" X 4.98"
c) Those are the rough ranges I see as far as I can calculate based on other images. I’m pretty confident from comparing multiple pictures that it is not both taller and wider than Ring, especially since that would mean those screwheads used as a base measurement and comparison are really abnormally massive screws…however, even if it was both wider and taller, the difference would still be pretty insignificant, tiny fractions of inches if anything. It looks to be pretty close to the same size as other high-end video doorbells, and probably smaller than most based on estimates from most screw-sizes.
Will there also be some wedge shapes available to be able to turn it facing forward if the connection is on the side of the door?
I found some photos online that showed a wedge mounting bracket that appears to be included with it, so I would say you can count on that being standardly available.
Granted, it’s not even a final officially launched product and things can change, and the official details and dimensions aren’t released yet, but I hope the rough estimates I calculated off images will satisfy someone else’s curiosity too.
