In a wireless communication system, a master device includes a wireless communicator that performs wireless communication with the slave device, a power supply that supplies power to each unit of the master device, an interrupt detector that detects various interrupts, and a controller that controls the entire master device, the interrupt detector supplies power from the power supply to each unit when detecting the interrupt, and the controller performs control to continuously transmit a capture signal to the slave device that waits for reception at a reception timing of a first predetermined interval, via the wireless communicator for time longer than the first predetermined interval when the detected interrupt is an interrupt that requests signal transmission to the slave device, and control to await a capture signal transmitted from the slave device through the wireless communicator when the detected interrupt is a timer interrupt occurring at a second predetermined interval.

In implementations described herein, A/V recording and communication doorbell devices (“A/V doorbells”) and signaling devices may be powered from a common AC waveform. In some implementations, an A/V doorbell and its corresponding signaling device may be arranged in a circuit loop where a portion of an AC waveform is used to power the A/V doorbell and the other portions of the AC waveform is used to power the signaling device. For example, a positive phase of the AC waveform may be used to power one of the A/V doorbell or signaling device and a negative phase of the AC waveform may be used to power the other of the A/V doorbell or signaling device. In some cases, an energy harvester device may be used to slow charge a battery or supercapacitor from the circuit loop to power the A/V doorbell and/or signaling device.

Cameras can be used to detect if a visitor enters a field of view. Cameras can be mounted in many different areas, including outside buildings, inside buildings, and near other items such as pools. Cameras can send alerts to remote computing devices regarding visitors. Thus, a user of a camera can see and even speak with visitors who are located far away from the user.

The information processing system includes: an analysis unit that analyzes a demand level of a plurality of reception desks based on a correlation between time and a characteristic of a visitor or a characteristic of a related item acquired from a video including the visitor visiting at least one facility including a plurality of different types of reception desks or the related item related to the visitor; and a determination unit that determines a distribution of personnel to the plurality of reception desks based on the demand level.

Methods, systems, and devices for security and/or automation systems are described. In some embodiments, the methods may include detecting an input at a doorbell, and communicating the detected input to a doorbell signal generating component associated with the doorbell based at least in part on the detecting. The methods may further include generating a first alert at the doorbell signal generating component associated with the doorbell. In some embodiments, the methods may further include communicating the detected input to one or more alert components associated with the security and/or automation system based at least in part on the detecting, and generating a second alert at the one or more alert components associated with the security and/or automation system.

A multi-channel video intercom system with access to advanced digital services includes a two-wire communication bus for audio, video, and data communications in different communication channels, at least one outdoor panel having a camera connected to the communication bus, at least one power supply connected to the communication bus to provide power to the rest of the video intercom system, at least one user terminal connected to the communication bus wherein at least one terminal is connected to the at least one outdoor panel, and wherein at least one terminal is a video intercom terminal. The system further includes a communications gateway connected to the communication bus through a first connection interface and Internet connected through a second connection interface wherein the gateway is allowed access to advanced digital services via the Internet from at least one video intercom terminal through at least one communication bus channel available for data.

Method is provided which includes mounting a touch screen protector to the front face of a portable electronic device. The front face has a declining surface portion extending along the outer perimeter thereof. The touch screen protector includes a planar sheet having a front side and a back side, an outer perimeter corresponding in shape to the device, and a transparent window portion. An opaque band is applied around the perimeter of the planar sheet, surrounding the transparent window portion. An adhesive layer is applied to the back side of the planar sheet for mounting the touch screen protector on the device. The planar sheet is sufficiently stiff such that a portion of the glass touch screen protector hangs over the declining surface portion of the front face of the portable electronic device when mounted thereon.

A control system includes a control module (34), a control device (20) mounted to a door (12) and controllable by the control module (34), and a manager mobile device (54) operable to connect with the control module (34) to obtain management authority to access to the door (12). The control device (20) includes a latch (24) for retaining the door (12) in a closed position. A vibration detecting unit (66) is mounted to the door (12) or the control device (20) and is electrically connected to the control module (34). When the vibration detecting unit (66) detects vibrations of the door (12) or the control device (20), the manager mobile device (54) is activated, and the image of the outside of the door (12) is transmitted to the manager mobile device (54), such that the manager can immediately know the situation outside the door (12).

A method of detecting and responding to a visitor to a smart home environment via an electronic greeting system of the smart home environment, including determining that a visitor is approaching an entryway of the smart home environment; initiating a facial recognition operation while the visitor is approaching the entryway; initiating an observation window in response to the determination that a visitor is approaching the entryway; obtaining context information from one or more sensors of the smart home environment during the observation window; and at the end of the time window, initiating a response to the detected approach of the visitor based on the context information and/or an outcome of the facial recognition operation.

The present invention relates generally to the field of cover plates. More specifically, the present invention relates to a smart plate device. The device is primarily comprised of a front plate that has a top surface, a side surface, and a rear surface further comprised of a box. The device can be installed as a cover plate for a light switch and/or a power outlet. Multiple devices can further be used in an intercom-like fashion within a home. Further, the device may have or be compatible with a virtual smart assistant that can be used to control the device and its functions. The device is also illuminated via an LED and can be controlled by the voice of the user.
