Laws vary by country, state and local laws. In general if signs are posted, it is because of a law.
Many will place the sign so that people know the audio may be recorded as well. Some states that is an issue, although we haven't seen many instances of someone getting cited for a Ring
doorbell. The laws simply haven't caught up yet.
If there were an issue with recording audio, one would hope the police would not be partnering with Ring and others to allow folks to be able to distribute their audio and video to them...If it were a big issue in your jurisdiction, I would hope they would not ask for it and jeopardize their case if a defense attorney could use it to make a claim to dismiss the case based on illegally obtained recordings....but we do see that happen on other items where they say the police illegally obtained information, searched, etc...
