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.

Abstract: Doorbell camera systems are provided that can include a doorbell camera subsystem and a chime subsystem. 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 battery and electronics that interface with a chime such as existing doorbell chime or a speaker. The battery is co-located with the chime subsystem and away from the doorbell camera subsystem. Co-locating the battery with the chime subsystem removes the battery from potentially harsh environmental conditions it would otherwise be subjected to if it was co-located with the doorbell camera subsystem.
