A method, performed by an image processing device, of encrypting image data includes: selecting an encryption target unit from among a plurality units constituting an image; generating a table including identification information about the encryption target unit; generating a first encryption unit including data obtained by encrypting the encryption target unit; generating a second encryption unit including data obtained by encrypting the table; and generating a bitstream including the first encryption unit, the second encryption unit, and units other than the encryption target unit among the plurality of units constituting the image.

Provided herein are systems and methods for implementing a video surveillance system. In one or more examples, the improved system can include a video managing system that applies one or more watchlists, to video footage captured by surveillance cameras to apply one or more processing policies indicated by the one or more watchlists. In some embodiments, a watchlist may indicate a plurality of events of interest (e.g., specific classes of objects, a presence of one or more persons, or one or more persons of interest, etc.) that should be detected from video footage. Through these mechanisms, video processing can be increased since the types of events of interest that need to be detected within the video footage are reduced. Non-transitory storage requirements are reduced, and human labor requirements to monitor, analyze, and review video surveillance footage is reduced.

The various embodiments described herein include methods, devices, and systems for providing event alerts. In one aspect, a method includes: (1) receiving a plurality of video frames from a camera, the plurality of video frames including a motion event candidate; (2) categorizing the motion event candidate by processing the plurality of video frames, the categorizing including: (a) associating the motion event candidate with a first category of a plurality of motion event categories; and (b) generating a confidence level for the association of the motion event candidate with the first category; and (3) sending an alert indicative of the first category and the confidence level to a user associated with the camera.

A method for partially unmasking an object in a video stream comprises: displaying a first video stream in which objects are covered by privacy masks; receiving user input regarding a selection of an object being covered by a privacy mask, wherein the object has a first portion being associated with a first privacy level and a second portion being associated with a second, higher, privacy level; checking that a permission associated with the user input grants access to video data depicting object portions being associated with the first privacy level; giving access to video data depicting the first portion of the object; and displaying a second video stream which differs from the first video stream in that it includes the video data depicting the first portion of the object, while the second portion of the object is still covered by a privacy mask.

Techniques for prioritization of media related to an incident are provided. Confirmed incident related media may be retrieved, the confirmed incident related media having been confirmed as being associated with the incident. Artifacts of interest may be identified in the confirmed incident related media. Presence of the artifacts of interest in a plurality of received media may be determined. The plurality of received media may be prioritized based on the presence of the artifacts of interest.

A computer implemented method of operating a video management system, the method comprising inputting, into the video management system, a plurality of virtual video streams generated by virtual video cameras within a dynamic 3D virtual environment; receiving, in the computer, at least one command from a user indicative of an instruction to alter a functioning of the dynamic 3D virtual environment and/or a functioning of the video management system; and displaying on a display, from the video management system, at least one virtual video stream and/or at least one alert, alarm and/or message implementing at least one alteration caused by the received command.

An event of interest may be tracked using a distributed intelligence video surveillance system. The distributed intelligence video surveillance system includes a lead video camera and a plurality of child video cameras that are configured to communicate with the lead video camera. One of the plurality of child video cameras may receive a video image and perform analytics and event generation for any events of interest found within the video image. The child video camera extracts metadata for any found events of interest and communicates the extracted metadata to the lead video camera. The lead video camera communicates the extracted metadata to others of the plurality of child video cameras so that the others of the plurality of child video cameras can be alerted to track the found events of interest.

At a high level, embodiments of the invention relate to augmenting video data with presence data derived from one or more proximity tags. More specifically, embodiments of the invention generate forensically authenticated recordings linking video imagery to the presence of specific objects in or near the recording. One embodiment of the invention includes video recording system comprising a camera, a wireless proximity tag reader, a storage memory and control circuitry operable to receive image data from the camera receive a proximity tag identifier identifying a proximity tag from the proximity tag reader, and store an encoded frame containing the image data and the proximity tag identity in the storage memory.

The present invention relates to an emergency alert system that triggers a distress event that is automatically managed by a community security system. The emergency alert system is activated through users' mobile devices and initiates communication with the community security system. Management by the community security system includes receiving the GPS location of the mobile device, recording a continuous stream of audio and video from the panic user's mobile application, notifying potential responders or groups of responders in the vicinity of the panic alert and, among other things, activating localized visual and audible deterrents present in surround private security systems, intelligently directing community CCTV cameras to record the distress event and issuing notifications to the closest community members for immediate responses, as well as other responder or group notification members.

A device may include a processor, a receiver, and a transmitter. The receiver may be configured to receive a content signal. The transmitter may be configured to transmit the content signal. The transmitter may be configured to transmit an associated inaudible signal. The content signal, the associated inaudible signal, or both, may be transmitted to one or more electronic devices. Each of the one or more electronic devices may be configured with audio interfaces. The receiver may be configured to receive a respective message from each of the one or more electronic devices. Each respective message may be based on the associated inaudible signal. Each respective message may include a respective electronic device identifier. The transmitter may be configured to transmit one of the respective messages.
