A status information receiver 420 for receiving status information about the DVR system transmitted from the processor 210, a system checker 430 for determining whether an abnormal operation of the DVR is performed using the received status information, and the system check When the action according to the abnormal operation state detected by the unit 430, that is, when the abnormal operation changes the setting contents of the occurrence portion, warns the operation state by the screen display as shown in FIG. 3, or is determined to be a serious problem. And an inspection result processing unit 440 which processes the inspection result such as calling the expert system (the upper management server) and calling it.

The system checker 430 determines whether there is an abnormality of the system through the check data transmitted from the digital video recorder 200. The hard disk capacity state, the camera operating state, the sensor operating state, the fan operating state, the system It includes data such as temperature, network connection status, camera input brightness and contrast, and normal operating conditions.

In this way, by checking the remaining capacity of the hard disk in advance, it is possible to prevent a situation in which recording is stopped during recording.

In addition, by checking the operating state of the camera, sensor, fan can easily determine whether there is an abnormality, by checking the temperature of the system can prevent the malfunction or stoppage of the digital video recorder 200 due to overheating in advance.

In addition, by checking the network connection state and the normal operation state with the camera, the audio input device, the sensor, and the like, the digital video recorder 200 has an easy structure to solve the abnormal state.

In addition, the check result processor 440 sends a warning message to the user when a risk factor is found, changes the part having an abnormal state, or calls a person in charge.

At this time, when the remaining hard disk capacity is insufficient, it is possible to replace the spare hard disk or delete unnecessary recordings by sending a warning message including the estimated time spent to the user.

In addition, when it is difficult to read the recorded video due to changes in the surrounding environment, it is of course possible to store a clear screen by adjusting brightness and contrast.

And if immediate action is needed or if an abnormal condition is found that cannot be solved by the user, the person in charge is automatically called and the user is notified.

When the system check is performed according to the state check progress of the digital video recorder, the screen display of the user check terminals 400a and 400b is performed as shown in FIG. 3.
