However, such a conventional CCTV pole system is not only large in size due to the design of the structure in consideration of the human load, but also damages aesthetics due to structures such as safety scaffolding, and there is a risk and inconvenience that a worker must climb to a high place.

In addition, the conventional CCTV pole system disclosed in the Republic of Korea Patent Publication No. 10-0981311 is to manufacture the structure of folding the pole body in multiple stages to adjust the height of the pole, the internal pressure of the multi-stage pole body is a controller, air compressor (Air Compressor), pressure sensor, pressure selection switch and so on.

However, such a conventional CCTV pole system can check the camera of the upper pole by using a ladder car or by folding the multi-stage pole, but the air compressor has to maintain a constant internal pressure of the multi-stage pole body at a relatively high maintenance cost. There is a problem that is difficult to lift and maintain. In addition, the CCTV pole system for installing an expensive CCTV camera in a high position should be easy to maintain the camera and ensure stability and reliability.However, the conventional CCTV pole system using a multi-stage pole body is used in a situation such as a momentary power failure. The internal pressure of the multistage pole body may decrease, thereby causing the multistage pole body to be folded or tilted.
