A method of an image sensor circuit includes: providing an event camera comprising at least one pixel unit; using the event camera to sense at least one current pixel value of the at least one pixel unit to detect whether at least one pixel value changes; when the at least one pixel value changes, using the event camera to trigger the digital processing circuit when the digital processing circuit is in a power saving mode and transmit information of the at least one pixel value to the digital processing circuit.

Some embodiments provide a method for separating the motion detection zone(s) of an A/V recording and communication device from the motion alert zone(s) of the A/V recording and communication device. For example, an A/V recording and communication device may be configured to generate motion alerts, and to record audio and video footage, when an event is detected within a selected motion alert zone (e.g., within a defined radius around the A/V recording and communication device). However, the A/V recording and communication device may not generate a motion alert for an event detected outside of the selected motion alert zone, even though the device may still record audio and video footage for the detected event (e.g., when the event is within a selected motion detection zone).

A battery-powered camera includes a system processor configured to operate in a standby mode or a full-power mode. While operating the system processor in the standby mode, the camera detects an event in a field of view of the camera; records, using an image sensor of the camera, a plurality of image frames corresponding to the field of view in which the event was detected; stores in a frame buffer the plurality of image frames; and wakes the system processor from the standby mode. While operating the system processor in the full-power mode, the camera processes the plurality of image frames stored in the frame buffer using the system processor; and provides the processed image frames for streaming.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving mission specific data. Converting the mission specific data into attribute classes recognizable by image recognition classifiers, where the image recognition classifiers are pre-trained to detect objects corresponding to the attributed classes within digital images. Obtaining, from a wearable camera system, low resolution images of a scene and high resolution images of the scene. Detecting, within the low resolution images using a low resolution image classifier, an object that corresponds to one of the attribute classes. In response to detecting the object that corresponds to one of the attribute classes, providing, for presentation to a user of the wearable camera system by a presentation system, an first alert indicating a potential detection of the suspect, and providing the high resolution images to a high resolution image classifier. Obtaining, from the high resolution image classifier, a confirmation of the detected object from the low resolution images. In response to obtaining the confirmation, providing, for presentation to the user by the presentation system, a second alert indicating confirmation that the object has been detected.

Provided are a doorbell system and a method of operating the same. The doorbell system includes a doorbell which includes: a camera configured to obtain at least one of an image of a first object in a first region and an image of a second object in a second region closer to the doorbell than the first region; an image processor configured to detect the first object from the image of the first object, and identify the second object from the image of the second object; and an alert generator configured to select and transmit to a user terminal an alert sound or alert sound information corresponding to the identified second object.

An image outputting apparatus comprises: a first accepting unit which accepts an output instruction of a captured image; and an outputting unit which outputs, in a case where, in the captured image captured at a first time point, a predetermined event occurs and the output instruction is accepted at a second time point after the occurrence of the predetermined event and the predetermined event is continuing at the second time point, the captured image captured by an imaging unit at and after the second time point, and outputs, in a case where the output instruction is accepted at the second time point and the predetermined event does not continue at the second time point, the captured image captured during the continuation of the predetermined event.

A recording control device includes a captured data acquisition unit that acquires captured data from a camera that captures a video of surroundings of a vehicle, a parking detection unit that detects that the vehicle is parked, a moving object detection unit that detects a moving object from captured data that is acquired by the captured data acquisition unit while the vehicle is parked, a person recognition unit that recognizes that the person detected by the moving object detection unit is a person, a behavior detection unit that detects that the person recognized by the person recognition unit is performing a specific behavior at a certain distance shorter than a predetermined distance from the vehicle, and a recording control unit that stores the captured data as event recording data if it is detected that the person is performing the specific behavior.

The disclosure is related to adaptive transcoding of video streams from a camera. A camera system includes a camera and a base station connected to each other in a first communication network, which can be a wireless network. When a user requests to view a video from the camera, the base station obtains a video stream from the camera, transcodes the video stream, based on one or more input parameters, to generate a transcoded video stream, and transmits the transcoded video stream to a user device. The base station can transcode the video stream locally, e.g., within the base station, or in a cloud network based on transcoding location factors. Further, the camera system can also determine whether to stream the video to the user directly from the base station or from the cloud network based on streaming location factors.

Systems and methods for dynamic communication and control of devices associated with a premises are disclosed. The systems and methods may include a device such as a camera that may be configured via configuration service to capture video of a premises and to transmit segments of the captured video having a pre-determined length of time to a video service. The transmission of the video segments may be periodic and may have a frequency of transmission based on parameters provided by the configuration service.

A video transmission apparatus detects a target object to be monitored from images obtained by imaging a monitoring area, tracks the detected target object, obtains existence time from appearance to disappearance of the target object, and transmits a data volume reduced image of the target object to a video reception apparatus. The video reception apparatus analyzes the data volume reduced image transmitted from the video transmission apparatus and transmits a video request of the target object to the video transmission apparatus) based on input made according to the result of the analysis. When the video request transmitted from the video reception apparatus is received, the video transmission apparatus generates a monitoring video from the appearance to the disappearance of the target object based on the existence time of the target object and transmits the monitoring video to the video reception apparatus.
