Abstract

<P>PROBLEM TO BE SOLVED: To provide a supervisory system capable of avoiding concentration of processing loads onto a supervisory recorder and concentration of communication loads onto a local part of a supervisory network caused by the processing load concentration. <P>SOLUTION: When view requests from all supervisory terminals are concentrated onto e.g. the supervisory recorder 131, the system allows the supervisory recorder 131 to transfer a supervisory video image having been recorded, to the supervisory recorder 132 and a management server 141 instructs the supervisory terminal to view it from the supervisory recorder 132. The view processing of the supervisory terminals for the supervisory video image having been recorded can be distributed to a plurality of the supervisory recorders so as to avoid the concentration of processing loads onto the supervisory recorders and the concentration of communication loads onto the local part of the supervisory network caused by the processing load concentration. <P>COPYRIGHT: (C)2003,JPO
