Abstract: This disclosure describes, in part, techniques for generating location information of an object along with a video that depicts the object. For instance, an electronic device may include a radar sensor that determines locations of the object. The electronic device may then store radar data representing at least the locations. Additionally, based on detecting an event, the electronic device may begin to generate image data representing the video. The electronic device may then analyze the radar data and the image data in order to determine that the object detected by the radar sensor includes the same object represented by the image data. As such, the electronic device may send the radar data and the image data to one or more computing devices. This way, a user device is able to display both the video depicting the object as well as the location information representing the motion of the object.

Abstract: This disclosure describes, in part, techniques for displaying location information of an object along with a video depicting the object. For instance, an electronic device may use a radar sensor to generate radar data representing the locations and an imaging device to generate image data representing the video. A user device may then use the image data to display the video. Additionally, the user device may display a map of a geographic area that includes the electronic device over a portion of the video. The electronic device then uses the radar data to determine positions on the map that corresponds to the locations. Using the positions, the electronic device displays interface elements representing the locations of the object. In some circumstances, the interface elements include different characteristics, such as colors, indicating a direction of motion of the object.

Abstract: An audio/video (A/V) device may include or accommodate a viewer through a barrier. For example, an A/V device may include a first component for installation on an exterior surface of a door, a second component for installation on an interior surface of the door, a viewer that extends through an opening in the door, and a flexible connector that electrically couples the first component and the second component. The A/V device may enable use of an existing hole in the door as part of a door viewer, while also providing the functionality of an A/V device. For example, the A/V device may be configured to receive an input using a button on the first component, generate image data using a camera on the first component, and send the image data to a network device.

Abstract: The application is directed to an electronic that includes multiple motion sensors, such as passive infrared sensors, that the electronic device uses to detect characteristics of objects. For instance, the motion sensors may be substantially vertically aligned and/or substantially horizontally aligned with one another, where each motion sensor is positioned at a respective angle with respect to a ground plane. When the motion sensors detect an object, the electronic device can then determine a direction at which the object is moving and/or a speed at which the object is moving. In some instances, the direction may include towards the electronic device or away from the electronic device. Additionally, based on the characteristics of the object, the electronic device may perform an action, such as generating image data using a camera and/or sending a user alert.

Abstract: Configuring motion detection by a security device. The security device includes a camera configured to capture images of an environment in front of the security device and a motion sensor for detecting motion within the environment. The system also includes a server and a client device that are interconnected by a network. An AI learning module interacts with a user of the client device to capture an image of the user within the environment in front of the security device, and determines parameters for the motion sensor based upon analysis of the image to determine a location of an exempt area relative to the security device. The motion detector is configured based upon the determined parameters.

Abstract: A system and visitor recognition method receives a first image of a detected visitor at a first location, compares the image of the detected visitor to a prior visitor model including images of prior visitors to the first location or a second location. In some embodiments, when an image of the detected visitor matches the images of the prior visitor captured at a time differing from the capture time of the image of the detected visitor, the detected visitor is determined as unknown. In some embodiments, when the image of the detected visitor matches a group of images of a prior visitor at the second location, and the number of times the prior visitor was previously detected at the second location is above a second threshold, the detected visitor is determined as known, even if the detected visitor was not detected at the first location at least a threshold number of times.

Abstract: A plurality of events may be captured by a set of audio/video (A/V) recording and communication devices. First video data of a first event and second video data of a second event may be received. The first video data and the second video data may be analyzed to determine characteristics associated with the first video data and the second video data. The first event and the second event may be prioritized based on the characteristics determined from the analysis of the first video data and the second video data to create an ordered list. The ordered list may include a first list entry that corresponds to the first event and a second list entry that corresponds to the second event. The ordered list may then be transmitted to a client device for display on a display of the client device.

A method determines that a person has entered the first field of view, determines that the person has left the first field of view, and determines that the person has entered the second field of view. The method sets a suspicious person warning flag, generates an alert, and transmits the alert to a client device that is associated with the first and second A/V recording and communication devices.

Abstract: Image comparison techniques allow a quick method of recognizing and identifying faces or other objects appearing in images. A series of quick distance calculations can be performed between an unknown input image and a reference image. These calculations may include facial detection, normalization, discrete cosine transform calculations, and threshold comparisons to determine whether an image is recognized. In the case of identification uncertainty, slower but more precise motion aligned distance calculations are initiated. Motion aligned distance calculations involve generating a set of downscaled images, determining motion field and motion field-based distances between an unknown input image and reference image, best scale factors for aligning an unknown input image with reference images, and calculating affine transformation matrices to modify and align an unknown input image with reference images.

Abstract: A server determines a plurality of faceprints representing a plurality of users to be recognized at a client device. Each faceprint contains a number of reference images for a given user that are used to recognize facial images of the user detecting in media captured at the client device. The faceprints delivered to the client device are determined for the client device based on the users likely to be detected in images captured at the client device. The reference images with a given faceprint delivered to the client device are selected by the server based on their recognition value in identifying the users likely to be detected in images captured at the client device.
