To report abnormality information with a high reliability by permitting a control means after receiving input detection not to execute the transmission processing of abnormality information in the case of no input detection from another input detecting means within a fixed time, to transmit abnormality information to a central monitoring device and to report only when it is estimated that an abnormality surely may have occurred with a high possibility.
When the reception of picture input detection from an image input detecting part 101 is recognized, the control part 109 of the monitoring device 100 sets the ON of an image input detection flag. When a certain kind of input detection is received and a timer is started for another input detection, it is considered that a plural kind of input detection is received so that the abnormality may have occurred, and then processing is shifted to the transmitting processing of abnormality detecting information. The control part 109 transmits abnormality information to the central monitoring device 200 when the abnormality is detected so that an origination processing instruction is outputted to a modem part 107. The modem part 107 receives it and connects a line by a dial processing.
