In the same time program check every frame, and try to find lightning there, if it will happen program will start save video (5 second before lightning + moment of lightning + 5 second after lightning) "5" second can be changed from 2 up to 300 seconds. The videos are saved to HHD, and it is possible to play the video in this program, save separate frame with lightning, or encode (to .avi or .mpeg4) and part of the video to be possible to play it with simple player. Program work with four pairs of cameras.
? System of radiational monitoring. Lot of checkpoints will send information to server, using modbus protocol. Server will check the data, and send it to clients, in case of receiving big values of radiational level, program will create alert, send it to client, and save it to database, in the same time every checkpoint have couple of video cameras, this cameras will save video with object of high radiational level.
