    Abstract: Doorbell camera systems are provided to include a doorbell camera subsystem and a chime subsystem both coupled to receive power from an alternating current power source. The doorbell camera subsystem may include, among other features, a camera module and a doorbell button. The chime subsystem may include, among other features, a current compensation network and chime driver circuitry operative to be coupled to a chime. The current compensation network is operative to dynamically adjust current consumption of the chime subsystem and current consumption of the doorbell camera subsystem during both a standby mode and a doorbell event mode.
