Event video recording and playback system, event management equipment, and local recording device

摘要

Cameras that are related to an alarm and the time period of the image that each camera records are defined in advance, and at the time of alarm occurrence, management data is made with reference to the definition contents. Surveillance object 231's transfer path 232 is presumed, and on the basis of this presumption, with each of cameras 203 to 205 installed along the pathway, the time periods of the images that are to be associated with an event are each delayed and defined. By this means, it is possible to record the suspicious behavior that surveillance object demonstrates at the time of alarm occurrence and the suspicious behavior that surveillance object 231 demonstrates on his transfer path to surveillance area 221 as an event image. Furthermore, it is possible to narrow down the time periods of images in which surveillance object 231 may be caught. IMAGE
