Electronic Doorbell System with Reduced Latency

A system for electronic monitoring includes a doorbell configured to immediately call a user following the occurrence of a trigger event, such as a doorbell button push or detection of motion or sound. The system reduces latency by omitting push notifications to the user, which require the user to open an application program on a device, and instead proceeds to immediately call the user's device following the trigger event. The call can be a telephone call enabled by a wirelessly connected base station or hub making a Voice over Internet Protocol (VoIP) call to the user's mobile device. In one aspect, a video stream captured by a camera positioned separately from the doorbell (for providing an optimum viewing angle of a visitor) can be synchronized by the base station with an audio stream captured by a microphone of the doorbell for communicating a synchronized media stream near instantaneously to the user while the user returns an audio stream to the doorbell during a phone call.
