If it had ONVIF support it would be the perfect firmware. But I'm not going to try it, hope someone with DB1 and ezviz fw could try ant let us know the updates.
EZVIZ Studio doesn't offer that update, but it's interesting reading the comment of latest ezviz firmware: I bet all issues with the chime not ringing we've seen lately are due to this "intelligent linkage" feature. Probably very badly implemented. Maybe they noticed all the support requests and fixed the issue. Let's wait for someone with DB1 and the chime issue and see if it fixes something.
