Matter is supposed to fix this. Apple can produce a doorbell and it would work with any Matter-enabled lock.if it did happen, apple doesn’t have enough of the supporting product to justify making the switch for me. My ring doorbell works with all the other ring security products I have. Also who wants indoor security cameras? I’d say the majority of security cameras sold are outdoor yes?
No one is going to install this in a house except as a hobby project until there is an industry-standard where we have an assured supply of compatible parts 30 years from now. Buildings have LONG lifetimes.
Apple's problem is that they like to update their products too fast. No one wants to have to upgrade all the light switches in their house every year. We expect them to last at least 20 years. Matter should fix this.
