Video camera having relational video database with analytics-produced metadata
First Claim
1. A network camera, comprising:
- a camera housing;
an imaging system configured to capture a field of view and generate video of the field of view;
a time-stamp block connected to the imaging system to receive the video, and configured to attach time stamps to the video;
video analytics configured to analyze the video to detect an object or an event of interest in the video, and to generate metadata corresponding to the object or the event of interest, the video analytics operatively connected to the time-stamp block so that the metadata generated by the video analytics is, by operation of the time stamps attached to the video, synchronized to the video generated by the imaging system;
a data storage system operatively connected to the imaging system and the video analytics to receive and store the synchronized video and metadata;
a rules based engine operatively connected to the video analytics to receive the metadata, the rules based engine configured to analyze the metadata and determine actions to be taken based on rules that associate the metadata with the actions, and further configured to determine content security levels for the video by applying rules included in the rules based engine;
a storage management system operatively connected to the rules based engine and the video analytics to control storage of the video in the data storage system; and
an access control management unit configured to control access to the video stored in the data storage system according to a user security level,wherein the metadata stored in the data storage system is searchable to allow the user to search the video stored in the data storage system and synchronized to the metadata, and the access control management unit controls access to the video stored in the data storage system such that a user is given access restricted to video having a content security level that corresponds to the user security level, andwherein each of the imaging system, the time-stamp block, the video analytics, the data storage system, the rules based engine, the storage management system, and the access control management unit either is contained in or forms part of the camera housing.

Abstract
Video analytics and a mass storage unit are contained in a camera housing of a video camera. The camera produces video data representing the field of view of a scene observed by the camera. The video analytics analyzes the video data and detects whether there is an occurrence of a defined feature of an object or a defined event of interest. The video analytics also generates metadata based upon the content of the video data. The video data and metadata are stored in the mass storage unit. Access to stored video data may be controlled based on content, and access to live video data may be controlled as metadata corresponding to the video data is created. The metadata can be used to search for corresponding video data representing the detected feature of an object or event of interest observed in the scene.

10. A method of controlling a network camera having a camera housing, the network camera including an imaging system, video analytics, a rules based engine, a data storage system, and an access control management unit, each of which either is contained in or forms part of the camera housing, the method comprising:
-
capturing and generating video of a field of view with the imaging system; attaching time-stamps to the video generated by the imaging system; using the video analytics to analyze the video to detect an object or an event of interest in the video; using the video analytics to generate metadata corresponding to the object or the event of interest, the metadata synchronized to the video by operation of the time stamps; analyzing the metadata with the rules based engine to determine actions to be taken based on rules that associate the metadata with the actions; determining content security levels for the video by applying rules included in the rules based engine; storing the video and the metadata in the data storage system; searching the video stored in the data storage system and synchronized to the metadata; and controlling, with the access control management unit, access to the stored video in the data storage system according to a user security level, such that a user is given access restricted to stored video having the content security level that corresponds to the user security level. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
