Apparatus and method for proactively alerting the user of potential threats and taking preventive actions to deter the intruder. The apparatus tracks the rear surrounding of the user and automatically detects potential threats in the form of unwanted advances by the strangers by tracking the safety zone around the user. The apparatus then alerts the user and the intruder by giving audio and/or visual signals. The warning alert switches to an emergency alert should the intruder continue advancing towards the user. Law enforcement and user's contacts are automatically dialed as part of the emergency protocol. Such footage also gets recorded for use by the law enforcement agency. This is the first apparatus that does automatic real time monitoring and performs preventative actions.

The disclosure includes a security system including an outdoor security device. In some embodiments, the outdoor security device comprises a housing, a light coupled to the housing and located within a hollow inner portion of the housing, and a camera and a lens coupled to the housing. In some embodiments, the security device comprises at least one directional microphone communicatively coupled to the camera and configured to determine a location of a detected sound whereby the camera performs a frame lock to capture an image associated with the detected sound.

An imaging system includes a stationary imager. An opaque enclosure includes a plurality of apertures at different locations on the enclosure and a plurality of stationary beam splitters arranged within the enclosure such that light that enters the enclosure through each of the apertures is directed to the imager. A shutter unit includes an opaque surface that includes at least one window. The shutter unit is rotatable relative to the enclosure such the window is sequentially aligned with each of the apertures to enable light from a field of view to enter the enclosure through that aperture, the opaque surface preventing light from concurrently entering the enclosure through more than one of the apertures.

This application relates to systems, methods, devices, and other techniques for a system with cameras and mirrors that can be utilized with an auto-checkout system within a retail environment. This system with cameras and mirrors is designed to have many functions within a store with auto-checkout system and sometimes can be utilized in a store with or without human cashier.

An apparatus, such as a doorbell, may include a doorbell housing. The doorbell housing may include a front surface facing exterior of a premises and a rear surface facing interior of the premises. A camera, doorbell activator, motion sensor, and/or light source may be at least partially positioned within the doorbell housing. An antenna may be positioned within the doorbell housing. The antenna may be configured to send a wireless signal comprising data to a data receiving device inside the premises. A reflective member may be positioned within the doorbell housing and configured to reflect at least a portion of the wireless signal that is sent toward the front surface of the doorbell housing.

The various implementations described herein include a video camera assembly that includes: (1) a housing; (2) an image sensor encased in the housing and configured to capture activity of the smart home environment; (3) a wireless radio configured to transmit video frames captured by the image sensor to an electronic device via a remote server; (4) at least one infrared transmitter configured to selectively illuminate the smart home environment; (5) one or more circuit boards encased in the housing, the one or more circuit boards including at least one processor mounted thereon; and (6) a heating component coupled to the image sensor, the heating component configured to continuously maintain the image sensor at a temperature above a threshold temperature while the image sensor is capturing the activity of the smart home environment.

Methods and devices related to reduced diffraction micro lens imaging are described. In an example, a method can include receiving light, via an array of micro lenses including embedded optics configured to reduce diffraction relative to a threshold value associated with another array of micro lenses without embedded optics, at an array of image sensors coupled to the array of micro lenses and positioned to receive the light in response to the light passing through the array of micro lenses, and generating an image from the light at the array of image sensors based at least in part on reduced diffraction of the light.

Systems and methods are disclosed for intelligently activating light devices for optimized lighting conditions in a scene, where optimized illumination is provided by a subset of light devices within an array of light devices in communication with the camera. The systems and methods detect a target within a camera's field of view and determine an optimized illumination of the target according to a video analytics model. Lighting is adjusted in accordance with the determined optimized illumination.

Methods, systems, and apparatus for camera detection of human activity with co-occurrence are disclosed. A method includes detecting a person in an image captured by a camera; in response to detecting the person in the image, determining optical flow in portions of a first set of images; determining that particular portions of the first set of images satisfy optical flow criteria; in response to determining that the particular portions of the first set of images satisfy optical flow criteria, classifying the particular portions of the first set of images as indicative of human activity; receiving a second set of images captured by the camera after the first set of images; and determining that the second set of images likely shows human activity based on analyzing portions of the second set of images that correspond to the particular portions of the first set of images classified as indicative of human activity.
