Abstract: This invention relates to the methods for preventing pollution of the glass of the front window of a housing for an outdoor surveillance video camera 2 and the housings in which they are implemented. On the external side of this glass 5, a pipe 3 is installed whose first butt end 8 is open to the environment and the second butt end closes the said glass. Using a blowing engine 10 installed in the housing, a pressure is being created in the pipe that exceeds the pressure outside the pipe; using a heater 11, an air flow is being heated in a closed body 1 of the housing and an air supplied to the blowing engine inlet is being cleaned using the filter 13. The microprocessor unit 12 controls the heater, the blowing engine, and the video camera. Technical result: prevention of dust, fogging, water drops, snow from accumulating and frost from depositing on the glass of the front window of the housing for the outdoor surveillance video camera.
