Humming/surge noise

Question

I installed my Ring Video Doorbell Pro Monday and everything seems to be working fine.  Early Tuesday morning (3:30) my wife shut off the outside porch light and the inside doorbell starting emitting a humming sound for about 20 seconds then the actual bell chimed.  Tuesday night at 9:30 pm the same thing happened.  Wednesday morning when she shut off the outside porch light the same thing happened.  Any idea what is causing this?

Hey @DJBillyO. How do you have the Doorbell Pro setup? Have you ensured there is a Pro Power Kit installed with the setup? Is the outdoor lighting fixture hooked up to similar wiring that the Pro is hooked up to when it comes to getting connected from the transformer?
