摘要:
An image recording device mounted to a vehicle includes an imaging unit for capturing a sequence of images including an image of a road that the vehicle is running and circumstances around the road by taking photographs; an image management unit for storing the captured images in a recording medium and for extracting a target image corresponding to a request for image transmission from the recording medium; and a communication unit for receiving the request for image transmission and for transmitting the extracted images to the external entity.

An authentication method capable of securing reliability and scalability by authenticating an authentication entity using a certificate signed by a symmetric key, when a user or device accesses a domain in which an authentication process is required are provided. The method includes: (a) allowing a home domain authentication server to generate a certificate and a symmetric key and to distribute the certificate and the symmetric key to an authentication entity; (b) allowing the authentication entity to submit the certificate to the home domain authentication server or an external domain authentication server; and (c) allowing the home domain authentication server or external domain authentication server to verify the validity of the submitted certificate by using the symmetric key. Accordingly, an effective authentication method can be provided in a public key-based authentication method in consideration of data processing capability or computing power.

A video surveillance system provides interface compatibility. The system includes a plurality of security devices connected to a network and configured to collect video data, a security server configured to make a connection request to a target security device to monitor the video data collected by the target security device, and an interface conversion server configured to convert the connection request in conformity to an interface of the target security device. The interface conversion server is further configured to convert the video data collected by the target security device having a non-standard interface in conformity to a standard interface in order for the security server to monitor the collected video data.
摘要:
A method for processing events in a server for a video surveillance system, includes: when the server detects occurrence of an event, transmitting a collection command to one or more cameras; analyzing specifications of the cameras, determining a set value for functions of cameras capable of processing the event, and transmitting a setting command to cameras; transmitting an execution command to the cameras, and processing and storing video data received from the cameras; and transmitting a completion command to the cameras, and completing the event processing. Each of the cameras including function units for performing different functions includes common frameworks which enable function units to perform the different function in a uniform manner.
