Abstract
An electronic door chime can meet safety standards and be compatible with smart doorbells and IOT doorbells. Current generation smart doorbells, also called IOT doorbells, require continuous power to drive the cameras, audio interfaces, and other components within the smart doorbell. Compatibility issues with prior art doorbell systems have emerged with the smart doorbell receiving inadequate power or power that doesn't meet the smart doorbell's input specification. In some cases, a prior art doorbell system is driven to failure or to excessive temperatures when the smart doorbell continuously draws too much power. A new electronic door chime can safely power the smart doorbells while also being compatible with simple push button doorbell devices.
