A focusing method of a camera for obtaining an image of a surveillance area by performing a pan-tilt-zoom (PTZ) operation is included. The focusing method includes: determining whether a region of interest set in the surveillance area is included in a first image obtained by the camera; converting a mode according to a result of the determination by selecting a first mode in which focusing is performed using a first focusing algorithm or a second mode in which focusing is performed using a second focusing algorithm that is different from the first focusing algorithm; and focusing the camera with respect to the first image according to the first mode or the second mode.

Focusing apparatus and method

A method of controlling zoom of a lighting unit based on brightness of an image may include determining at least one of an angle of view of an optical unit and an optical zoom magnification of the optical unit configured to obtain an image by using an image sensor, determining a zoom adjustment range of a lighting unit based on at least one of the angle of view and the optical zoom magnification, and adjusting zoom of the lighting unit such that brightness of the image meets a preset condition within the zoom adjustment range, wherein a diffusion range of light from the lighting unit is adjusted through the zoom adjustment of the lighting unit.
