A patient fall prediction system receives video image frames from a surveillance camera positioned in a patient's room and analyses the video image frames for movement that may be a precursor to a patient fall. In set up phase, the viewpoint of the camera is directed at a risk area associated with patient falls, beds, chairs, wheelchairs, etc. A risk area is defined graphically in the viewport. The patient fall prediction system generates a plurality of concurrent motion detection zones that are situated proximate to the graphic markings of the risk areas. These motion detection zones are monitored for changes between video image frames that indicate a movement. The pattern of detections is recorded and compared to a fall movement detection signature. One fall movement detection signature is a sequential detection order from the motion detection zone closest to the risk area in the frames associated with patient falls, to the motion detection zone farthest away from the risk area. The patient fall prediction system continually monitors the motion detection zones for changes between image frames and compiles detections lists that are compared to known movement detection signatures, such as a fall movement detection signature. Once a match is identified, the patient fall prediction system issues a fall warning to a healthcare provider.

A PC is authenticated by a server (SEQ100). When a monitoring start request is issued (SEQ101), an in-house security unit generates a one-time key (SEQ106). The one-time key and information ex. a port number with which the PC is connected to the in-house security unit is passed to the PC through the server (SEQ110). The PC and the in-house security unit are connected in PtoP (SEQ111). The in-house security unit encrypts a picture photographed by the surveillance camera with the one-time key and then streamingly transmits the encrypted picture data to the PC (SEQ114). The PC decrypts the received stream data with the pre-received one-time key, restores the original picture, and displays the restored original picture on a display portion. When a monitoring stop request is sent from the PC to the in-house security unit (SEQ112, 123), the in-house security unit deletes the one-time key (SEQ124).

The present invention is a video surveillance, storage, and alerting system having the following components. One or more surveillance cameras capture video data having attribute data, the attribute data representing importance of the surveillance cameras. One or more video analytics devices process the video data from one or more of the surveillance cameras and detect primitive video events in the video data. A network management module monitors network status of the surveillance cameras, and the video analytics devices, and generates network events reflective of the network status of all subsystems. A correlation engine correlates two or more primitive video events from the video analytics devices weighted by the attribute data of the surveillance cameras used to capture the video data, and network events from the network management module weighted by attribute data of device corresponding to the network event. An alerting engine generates one or more alerts and performs one or more actions based on the correlation performed by the correlation engine.

One embodiment is a method of storing video data from a video surveillance system having one or more cameras. Video data is captured from one or more surveillance cameras. Meta-data is automatically generated by performing video analysis on the captured video data from the surveillance cameras. A human operator may manually enter additional meta-data. Attribute data and associated weights, representing information about the relevance of the meta-data, is received. The video data is stored in a hierarchical video storage area; the meta-data, indexed by date and time stamp to the video data, is stored in a meta-data storage area; and the attribute data is stored in an attribute storage area. One or more alerts may be issued based on the past and present meta-data. The video data is secured by encrypting and storing the video data remotely, and audit trails are generated about who and when viewed the video data.

A surveillance camera device with a light source is composed of a camera, a control unit which is connected to the camera, a light-source control unit which is connected to the control unit, and a light source. The control unit directly gets the illumination of images captured by the camera or its related parameters, to determine whether illumination of the environment of image captured is sufficient. When the illumination of the environment of image captured is changed, the control unit will send lighting control signal to the light-source control unit to activate or deactivate the light source, or adjust the light output intensity of the light source automatically, such that the illumination of the environment of the images captured can be accurately determined to provide the correct light fill-in for shooting clear images.

A camera and a remote device wirelessly communicate data and commands over a first channel using respective wireless transceivers. The wireless transceiver of the camera is normally operated in a sleep mode. The remote device transmits a wake up signal on a second channel to a receiver in the camera, wherein the wireless transceiver in the camera is woken and communication is established over the first channel. The wireless unit on the camera is removably coupled thereto so that the cameras can operate with or without the unit.

A wide-angle camera is fixed to direct an optical axis in a fixed direction. A telephotographic camera can be inclined in panning and tilting directions to change an aiming direction of its optical axis. An image signal from the wide-angle camera is evaluated. When an image of a moving object is identified in a frame captured by the wide-angle camera, directivity information corresponding to a position of the moving object is calculated based on a relative position to the center of the frame. In accordance with the directivity information, posture of the telephotographic camera is controlled to aim its optical axis at the moving object. Thereafter, the posture of the telephotographic camera is controlled continuously to place the image of the moving object in the center of the frame captured by the telephotographic camera. The telephotographic camera captures the moving object while tracking it.

A system and method for enabling real-time off-site video image storage is disclosed. An off-site storage site is coupled to camera servers at client sites via a private network. Each camera server is further coupled to one or more surveillance cameras. Video images captured by cameras located at the client sites are forwarded to an off-site server via a camera server. Video images received by the off-site server are produced for live viewing and/or archived in an image database. Users can retrieve live or archived video images through a client workstation that communicates with the off-site server over the public Internet. Retrieval of video images is based on a web-browser interface. Live viewing of video images is supplemented by real-time camera control functions that alter the pan-tilt-zoom (PTZ) position of the camera producing the live images. Commands for controlling the PTZ camera are encoded by the client workstation and transmitted to the off-site server. The off-site server converts the camera control codes into control strings that are recognizable by the particular camera.

A video surveillance system that automatically keeps track of a moving object in an accurate and efficient manner. The system has two cameras for surveillance. One is a visible-light integrating camera that has a frame integration function to capture visible-light images of objects, and the other is an infrared camera for taking infrared images. A rotation unit tilts and pans the visible-light integrating camera and/or infrared camera, under the control of a tracking controller. Video output signals of those cameras are processed by image processors. The tracking controller operates with commands from a system controller, so that it will keep track of a moving object with the visible-light integrating camera in a first period and with the infrared camera in a second period.
