Description

Technical Field The present invention relates to a monitoring system and a monitoring device for monitoring a video of the peripheral region of a construction machine captured with a camera of the construction machine, and the construction machine therefor. Background Art In the construction industry, there is demand for a construction machine, a construction management system, and a tool, for example, that can improve productivity or security from the perspectives of eliminating labor shortages or preventing industrial accidents. Meanwhile, there has been provided a video providing system like a dashboard camera that is disposed on a construction machine, and records and distributes a video. According to such a video providing system, it is possible to review operations performed at a construction site or check the progress of a construction work, for example, using the video, which helps a lot to improve productivity or security at the construction site. According to Patent Literature 1 (see the abstract), an image of a region (1) around a piling construction site is captured with an imaging means (3), and the construction status of a pile (2) is constantly monitored in real time. The imaging means is mounted on a heavy machine (5), and the imaging means of the heavy machine is connected to an external terminal device (6) so as to be able to transmit and receive data to and from the external terminal device. Data (7) on a moving image or a still image of the region around the piling construction site captured with the imaging means of the heavy machine is constantly transmitted to the external terminal device so that the real-time construction status of the pile is visualized with the terminal device based on the data on the moving image or the still image. A construction machine management system of Patent Literature 2 (see the abstract) includes a traveling body, a work implement connected to the traveling body, a maneuvering region provided in the traveling body, a drive control unit that controls the operations of the work implement and the traveling body, an operation unit that is arranged in the maneuvering region and operates the work implement, a maneuvering seat that is arranged in the maneuvering region and on which an operator is seated, a connection terminal that is arranged in the maneuvering region and is connected to a portable terminal, a vehicle body control unit that communicates with the portable terminal and controls each unit, and a storage unit that stores authentication information. When the portable terminal is connected to the connection terminal, the vehicle body control unit checks authentication information transmitted from the portable terminal against the authentication information stored in the storage unit. If the two authentication information match, an action to be taken in response to an input operation is determined to be executable. If the two information do not match, the operations of the work implement and the traveling body are prohibited. Patent Literature 3 discloses a shovel, which is connected to an external management device in a communication manner, which comprises an engine, and is configured to receive a first password as authentication information issued by the management device, and allow the engine to start on the basis of the authentication result by the first password. Citation List Patent Literature Patent Literature 1: JP 2019-193062 APatent Literature 2: JP 2018-114978 APatent Literature 3: WO 2021/024965 A1 Summary of Invention Technical Problem As described above, according to Patent Literature 1, the data (7) on a moving image or a still image of the region (1) around the piling construction site captured with the imaging means (3) of the heavy machine (5) is constantly transmitted to the external terminal device (6) so that the real-time construction status of the pile (2) is visualized with the terminal device based on the image (see the abstract). However, Patent Literature 1 describes neither a specific connection between the imaging means provided on the heavy machine and the external terminal device, nor a specific authentication method or the like, and thus has a problem with the handling of the image data. In particular, the image of the region around the construction site includes an operator's face, and conveys the progress of the construction work at the construction site, for example, which means that the data has attributes close to (personal) information that should be owned by the manager of the construction site. Thus, leakage of the data to outsiders needs to be avoided. Although Patent Literature 2 discloses an authentication method, the system of Patent Literature 2 requires a contact (i.e., a physical contact) between the connection terminal in the maneuvering region and the portable terminal during authentication (see the abstract). Therefore, a video or an image (i.e., a moving image or a still image; hereinafter referred t
