You can arbitrarily select the required information from the list and display it in combination on the screen, and you can easily check the elevator operation information and date and time information on the screen that can not be recognized only by the video information taken by the surveillance camera .

Since the image of the elevator monitoring camera and the operation status information and date and time information of the elevator can be recorded in synchronization with each other in synchronization with each other, the recorded monitoring image can be recorded together with the operation status of the elevator. At the time of management and reproduction and display in chronological order, the target monitoring image can be easily searched and confirmed by arbitrarily specifying the operation state of the elevator.

A change in the surveillance image taken by the surveillance camera of the elevator is detected, for example, a state where a person gets on and off the vehicle is detected, and a monitoring video at that timing is recorded. The status can be recorded. Accordingly, recording can be performed only when a person is shown, and it becomes easy to select a scene necessary for reproducing a monitoring image later.

The video of the surveillance camera is encoded and individually recorded as image data, decoded at the time of reproduction, a visible image is reproduced, and date and time information and elevator operating state information are combined to form a display screen. It is possible to compose a screen by combining only necessary information in accordance with a display style, or to divide a display area and display a plurality of screens at the same time, and compare monitoring images on the screen.

In order to record the operating state information of the elevator in association with the image of the monitoring camera of the elevator,
A monitoring image can be searched for by designating an elevator operating condition, and a target image can be quickly searched and confirmed from a large number of monitoring images.

By parameterizing the recording condition, the retrieval condition, and the display condition, it is possible to monitor repeatedly under the same condition without specifying the condition each time.

Since the recording conditions, retrieval conditions and display conditions, which are parameterized, can be stored and changed, necessary conditions can be designated according to the purpose.
