FIELD: physics, video.SUBSTANCE: invention relates to panoramic television surveillance. The result is achieved due to that surveillance is carried out by a television system through a television camera with all-round view in a region close to a hemisphere, i.e., in a spatial angle of 360 degrees on the azimuth and tens of degrees on the elevation angle. Panoramic colour or black and white images are automatically transmitted to the server of a local area network depending on the time of the day, wherein monochromatic video signals are detected therein with a high signal-to-noise ratio.EFFECT: providing an operator with a colour image during the day and a black and white image during the evening and night in automatic switching mode and with a high signal-to-noise ratio for a monochromatic image.4 cl, 11 dwg |
