Abstract
In some embodiments, a video doorbell system includes a video doorbell device on an exterior surface of a structure and a chime kit within an interior of the structure. A transformer can be coupled in-series via electrical conductors with the video doorbell device and the chime kit. The chime kit can include an energy storage device that is charged via the electrical conductors. When a user activates a button on the video doorbell device power control circuitry within the video doorbell device can transmit a signal on the electrical conductors. Button detection circuitry within the chime kit can detect the signal and respond by transferring power from the energy storage device to a chime. While the chime is activated the transformer can continuously supply the video doorbell device with power.
