The study of the factors that form the threats to the violation of the properties of the availability and integrity of aeromonitoring video information in the system of prevention and elimination of crisis situations. The direction of increasing the availability of video information based on the use of compression technology for encoding video data has been substantiated. It is shown that to eliminate the drawback associated with lowering the lower boundary of the differential polyadic space, it is necessary for the perforation technology to additionally take into account the binary mask of burst elements of the upper and lower levels. The main conceptual components of the image compression method to increase the availability of video information, based on the coding of composite numbers with a mask in a differential perforated polyadic space, have been developed. The main results of a comparative assessment of the basic component of information availability in aeromonitoring systems are presented.
