摘要： An event surveillance system includes: a network camera for monitoring real-time video images to perform event tracking on an event occurred therein; and at least one machine-to-machine agent, connected to the network camera and devices in a network, for providing protocols for data communications between the network camera and the devices. If the machine-to-machine agent receives information on the event occurred in the network camera, the machine-to-machine agent requests the devices to provide event information for use in verifying accuracy of the event and verifies the accuracy of the event based on the event information provided by the devices. The network camera monitors in real time the event verified to be accurate.

摘要： Provided are a system and a method for reducing a communication load of an apparatus for tracking a moving object. The system includes: an estimated necessary time calculating unit receiving a current location and an arrival location of the moving object from a terminal included in the moving object, calculating estimated necessary time for the moving object to reach the arrival location, and transmitting the estimated necessary time to the terminal; and a communication path on-off controlling unit activating a communication path for the terminal to receive the estimated necessary time from the estimated necessary time calculating unit, and inactivating the communication path when the terminal receives the estimated necessary time through the communication path.

摘要： In existing moving object tracking, there is a great communication load between a terminal and a platform, because the terminal should report its location to the platform every second or every minute and the platform should frequently process the location form the terminal. It is possible to reduce the great communication load on the server, by calculating an error between the current GPS location and the estimated location at a specific time on the basis of the estimated arrival time of the moving object. It allows that the terminal report its location to the server only when the error between current GPS location and the estimated location is greater than a predetermined threshold value.
