Doorbells can be used to detect visitors. A picture taken by the doorbell can be sent to a computing device. A user of the computing device can select areas within the picture. The doorbell can then detect visitors within the selected areas. Subsequent pictures from the doorbell can be analyzed according to the selected areas.

A monitor system includes an outdoor doorbell module integrated with video and audio transmission, an indoor remote receiver and a signal transmission interface. The doorbell module includes a depressible button and a micro-camera and a sound detector actuated by the button to obtain visual image and sounds of the visitor. The remote receiver includes a signal receiver circuit to receive the doorbell actuation signal and the visual image and sounds from the doorbell module, an alarm generator activated by the doorbell actuation signal to ring, and a driver circuit generating control signals to control a monitoring device and a recording device. When the button is actuated by the visitor, the remote receiver receives the doorbell actuation signal and generates the ring. At the same time, the doorbell module activates the micro-camera and the sound detector to obtain visual image and sounds of the visitor. The visual image and sounds are transmitted to the remote receiver and then displayed by the monitoring device and selectively recorded by the recording device.

The present invention pertains to a wireless audio-video doorbell monitoring system, wherein a portable monitoring device administrates a doorbell device and detective devices. After initiation, the monitoring device calls other nearby devices to form a wireless network via a wireless broadcasting way, and then the monitoring device administrates each device to perform the doorbell or detection function. Via the automatic setup and simple operating interface, the present invention enables a general family to be free from a complex operational procedure. In the present invention, the detective device can sense the image and sound of the monitored regions, which is sent to a display panel and a speaker of the monitoring device without a time lag. Accordingly, the present invention provides an instantaneously-displaying and easy-operated wireless audio-video doorbell monitoring system, which is easy installed, automatically set up, highly securing, able to reduce the power consumption efficiently and suitable for a general family usage.

Doorbell systems can include a doorbell and a chime. In some embodiments, the chime can be communicatively coupled to a wireless network of a building, to the doorbell, and to a remote computing device. In several embodiments, the chime facilitates communication with at least one of the doorbell, the remote computing device, and a remote sensor.

Doorbells can include a speaker and a visitor detection system having at least one of a button, a camera, and a motion detector. The speaker of the doorbell can be configurable to emit a first sound in response to the visitor detection system detecting a first indication of a visitor's presence. As well, the speaker of the doorbell can be configurable to emit a second sound in response to the visitor detection system detecting a second indication of the visitor's presence.

Doorbells can communicate wirelessly with remotely located computing devices. In some embodiments, doorbells include an antenna configured to enable the doorbells to communicate wirelessly with remotely located computing devices. The antenna can exit the back side of a doorbell and enter a hole of a building such that the antenna is located in the same hole as electrical wires that provide electricity to the doorbell.

A surveillance system is provided having a base unit for receiving digital video and audio transmissions from accessory units equipped with a camera having pan and tilt functions, a motion sensor, an intercom, infrared sensors and a doorbell button for contacting the interior of the dwelling a recording feature is provided to both automatically and on demand record video and audio transmissions received by the base unit from the accessory units.

Methods can include using a doorbell to wirelessly communicate with a remotely located computing device. Doorbells can include a speaker, a microphone, a camera, and a button to sound a chime. Some embodiments include using a doorbell to close an electrical circuit that has a sound output device in a way that precludes the sound output device from inappropriately emitting a notification sound.
