Abstract: The position and time tracking system based on photographs comprises a host and a client connected via network. The client's memory is saved in with an input, which controls at least two imaging devices together with a variable-checking device. At least the client's position and time tracking variables are compared with rules that are input from the host via a user interface unit in authorising the imaging devices to take image input, where acquired images are compressed with the checked variables, and a data storage unit checks network connection's stability and transmits data to the host once the connection is stable. Conversely, if the connection is unstable, images are saved into the client's memory, and data are transmitted to the host when the connection has been stable.
