[0002] Monitor refers to the general term for using video storage devices to collect and store video and audio signals. Surveillance cameras are widely used in various fields.

[0003] At present, when the monitor is installed, the monitoring range of the camera needs to be adjusted. However, it is not convenient to adjust the tilt angle of the installed camera, which brings inconvenience to the staff. In addition, the exposed camera is easily damaged by accidental impact, which reduces the protective safety of the camera.

[0004] For example, announcement number CN216556188U discloses a NB-IOT-based security monitor, which includes a monitor, and the monitor includes a supporting device and a fixing device, the supporting device is installed at the front end of the monitor, and the fixing device is installed at the back of the monitor.

[0005] It can be seen from the above-mentioned public scheme that the protective frame cannot protect the front lens of the camera, and dust easily sticks to the surface of the lens, reducing the shooting clarity. In addition, the tilt angle between the protective frame and the support rod cannot be adjusted, so that the camera cannot adjust the shooting angle, which brings inconvenience to the monitoring range adjustment.
