The present invention provides a lift type closed-circuit TV (CCTV) camera system comprising: a main unit having a hollow drum installed at a preset height and on which a wire rope can be wound, and a drive motor installed thereto to provide rotational force to the drum; a lift body hung on the wire rope and combined to a CCTV camera in a lower end thereof; a coupling unit having an accommodation structure which is placed in the lower part of the main unit and has an opened lower part to be combined with the elevation body, and a stopper installed in the accommodation structure to provide a fall prevention function for the elevation body; and an upper and a lower contact unit installed in the main unit and the elevation body, respectively, and making contact with each other when the elevation body is lifted by winding the wire rope and is combined with the main unit. When combination between the main unit and the elevation body is completed, and the upper and the lower contact unit make contact with each other, a stopper locking unit of the elevation body is installed and separated from the stopper at an upward preset interval, so the wire rope supporting the elevation body keeps a tense state. |
