室內門鈴電源板

This little board completely eliminated the hum that appeared after I installed my new doorbell camera. Took less than five minutes to wire in and now the chime sounds perfectly silent between rings.

Installation took maybe ten minutes and the constant buzz from the chime is basically gone now. I still catch a faint hum if I put my ear right up to it, but nothing noticeable from across the room.

The buzzing from my chime was driving me nuts after I hooked up a video doorbell, and this board mostly cleared it up. Wiring it in took a little fiddling since the terminals are small, but once it was seated the hum dropped to nearly nothing.
