The indoor mini cameras have been set up as chimes for the doorbell.
However, they do not sound off every time the doorbell button is pressed. The chime in the doorbell itself does go off each time the button is pressed.
It appears the indoor cameras will not chime again until their green flashing light turns off. This seems to take about 30 seconds. That's quite a long time for a doorbell chime.
Seems odd in having a chime go off outside of the house but not inside.
