As cameras have siren that you can set off. Is that something that still can be done with the battery doorbell hardware with firmware upgrade? Would love to have that if have unwanted person at the door.
If the siren isn’t already built into the doorbell, probably won’t happen via a firmware update. One thing you could do is take advantage of the custom responses. Record whatever siren you want and then you could play that back if something fishy is happening at the doorbell.
Yes!!! The doorbell cam needs a siren.
