2 weeks ago If it's a hardwired (has no battery), 1920x1080 resolution (full hd) and tuya, with a similar layout, then chances are it could work. That said, if you haven't bought anything yet, my advice would be to just get something that has everything you need out of the box (i.e. onvif/rtsp/option for no cloud connection). I have a number of cameras that meet that criteria and I'm pretty sure there are many doorbells that support that as well now.
I will add that specifically for doorbell, the cloud function is actually a big pro -- a lot of doorbells will notify your phone (anywhere) over the cloud. You would have to build everything yourself to replicate that feature which is quite a bit of work. I put my doorbell on a 'guest' type network which is isolated from my devices at home so it can't be used to spy on me (but could still be used as a bot on my internet). I have seen the code in many of these devices and have seen no indication of any bot-like code in them.
I want to have a offline (no cloud) doorbell, but there are so many tuya products I don't know which one I can use Any advice ? Many thanks
