A CCTV camera housing having a glass washing function is provided to perform special coating on the front surface of the housing and apply ultrasonic vibration periodically on a glass surface to wash, thereby simplifying structure, reducing installation costs, and having high washing efficiency with easy maintenance. A camera(20) is installed inside a housing main body(10). A glass member is installed at the front of the housing. A coating film(60) is formed so that the surface of the glass member is flat. An ultrasonic generator is installed in one side of the housing main body. One or more vibrating units(50) are installed at one side of the glass member. A vibrating unit applies vibration to the glass member by an ultrasonic signal applied from the ultrasonic generator. Therefore, the vibrating unit washes the glass member. A timer is installed between the ultrasonic generator and vibrating unit. The Timer controls the operating time of the vibrating unit.
