Claim:
1. A forest fire video monitoring system comprising: at least one remotely controlled video monitoring point which includes a high-rise construction and a transmission-side equipment residing on the high-rise construction, the transmission-side equipment comprising: a video camera on a rotating device; and a camera control unit configured to determine a current spatial orientation of the video camera in a native coordinate system of the video camera; at least one computerized operator workstation for operating said video monitoring point; and a computer-implemented module configured: in each of at least two predetermined time moments, to obtain an orientation of the video camera aimed at a known astronomical object, said orientation determined by the camera control unit in the native coordinate system of the video camera, and to determine, based on a predetermined location of the video monitoring point and said at least two predetermined time moments, a position of the astronomical object in an absolute coordinate system centered in a point in which the video camera resides, and to calculate, based on the determined orientations of the video camera and positions of the astronomical object, a rotation of the native coordinate system of the video camera in the absolute coordinate system.
