For the analysis the risk from particles of meteor streams, we must have proved information about masses and densities of meteors. The prime task is to select minor streams from sporadic meteors. Very few astronomers tried to do it, when others only mark observed meteor “Sporadic” without registering its track. So very few previous observations cannot be used for streams detection, and we had to do it from special observations. As a width of meteoroid stream may be very narrow, the Earth will cross it in few hours and it is necessary to observe meteor events 24 hour a day. This is why we provide meteor monitoring and catch every ray of light in night skies and ask other observers to join our program. The current goal of our investigation is continuous monitoring of meteor events by two ways: from nearby sites (about 20-60 km distance) for triangle observations and simultaneously from some observation sites separated by approximately thousand kilometers for detection of minor streams. The last one will reveal spatial heterogeneity's of strong meteor showers also. Since July 2002 at the Arkhyz Space Tracking Station (North Caucasus) and near Moscow hybrid TV-cameras with CCD (“PatrolCa”) are used for meteor observations. Limiting magnitude of the first camera is about +5 magn in the 52-degrees field under frame rate 25 f/sec, the second camera has limiting magnitude 11,5m in field 18x22 degrees with rate 7,5 f/sec. Since June 2006 four extra PatrolCa begin stereo (basis) TV-observation near Moscow with the aims of determination of individual orbits of observed meteors and their physical densities. Observed by meteor monitoring data show that at least 40% of sporadic meteors may be referred to catalogued weak meteor streams. In this paper we present the method of definition of celestial coordinates of objects in the single frame of the wide-angle system. The method allows definition of celestial coordinates of a meteor at the restrictions of absents of enough stars in the frame during the observations, for example at partially cloudy weather, or when there are few stars in the frame, or at large distortions of a coordinate grid in the frame. These restrictions can forbid direct using of other methods. We objectively registered 38 meteors with wide-angle camera “PatrolCA” during 9 nights from 2002 to 2007 years and 2000 meteors with highly sensitive camera FAVOR during 1000 nights at the same period.
