I have a doorbell with camera, and also two security cameras that are not part of the doorbell system.

I can watch someone ring the doorbell with either the doorbell camera or both security cameras. There is about a five second delay from the time the button is pushed until the chime inside the house rings. There is no audible sound before then. Except... the dogs go berserk, warning of barbarians at the gate the moment that button is pressed.

Question "a": How is this possible?
Question "2": How can I fix this?
