The present invention relates to an apparatus for adjusting the back focus of a surveillance camera. The apparatus for adjusting the back focus of a surveillance camera according to the present invention comprises: a lens unit on one side; an image sensor on the other side; and a back focus adjustment unit which includes a rotating ring, an image sensor ring, and a rotation driver, which adjust a back focus distance from the lens unit by moving the image sensor forward and backward, and a sensor. The apparatus for adjusting the back focus of a surveillance camera easily adjusts a back focus distance remotely by moving the image sensor ring forward and backward using a motor which rotates the rotating ring, and conveniently adjusts a back focus distance of a surveillance camera without going up to the surveillance camera or moving required equipment by remotely adjusting a back focus distance of the surveillance camera, thereby improving work efficiency. |
