As a motor for performing the above steps, a stepping motor capable of precise angle control is used.

Next, referring to FIG. 2, the warning sound output step S400 is performed at the same time as the camera control step and outputs a warning sound to the speaker 40.

Here, the warning sound output step, as a means for warning the person who has impacted in close proximity to the CCTV through the warning sound, the warning sound is also propagated in the vicinity of the CCTV, thereby preventing the CCTV cut in advance.

Next, the remote notification step (S500), if there is an additional detection signal from the infrared sensor and the shock sensor after performing the warning sound output step, by the wired or wireless communication remote control CCTV server 50 or administrator's smartphone The image and location information recorded at 60 are displayed and a warning sound is output to induce a quick response of the administrator.

Here, in the remote notification step, if there is no additional detection signal from the infrared sensor and the shock sensor for a predetermined time after performing the warning sound output step (S400), the shock sensor is turned off (OFF) and the CCTV camera returns to its original position The step is configured.

In other words, the remote notification notification step, even if the warning sound output to the person with a CCTV cut signal that has been impacted in close proximity to the CCTV through the warning sound output step, the microcomputer 100 ignores this and shocks the CCTV. Receiving the detection signal to determine the CCTV cut off and notify it to the remote CCTV control center server or administrator's smartphone.

Finally, the remote operation step (S600), after performing the remote notification notification step, the administrator via the smartphone of the CCTV management center server or the administrator of the remote control the pan / tilt / zoom (pan / tilt / zoom) drive driver It is a step to secure the evidence of the cut-off of the CCTV camera for the impression of the cut-off and the vehicle number by remote operation.

In other words, the remote operation step, pan / tilt / zoom (pan / tilt / pan / tilt / so that the camera number of the cut-out or the cut-out of the CCTV cut-out site can be photographed through the remote CCTV control center server or administrator's smartphone) zoom) By remotely operating the driving driver, the CCTV camera can zoom in the vehicle number of the person who cut off or the person who has cut off, so that the evidence of the evidence of the CCTV camera can be obtained.
