摘要:
A network system capable of suppressing system scale is provided and such a system can be used even for an ad-hoc type system. The network system enables synchronization of a sensor node 1 with other sensor nodes 1 in measured time. Each sensor node 1 uses time-series data that is repeatedly transferred among the sensor nodes 1 existing on the network to calculate an average time measured by timers 14 of other sensor nodes 1 existing on the network and sets the time of the timer 14 of the own sensor node 1 to the average time.

A monitoring camera terminal is provided that may sufficiently ensure the identification accuracy of a traced person such as a suspicious person with respect to any other monitoring camera terminals and may sufficiently limit the cost increase. Two adjacent monitoring camera terminals (1) have partially overlapping imaging areas. The monitoring camera terminal (1) transforms a person position in a frame image imaged by the own-terminal and a person position in a frame image imaged by the adjacent other monitoring camera terminal (1) into respective positions in a common coordinate system. Feet position distances between the persons are used to perform identification to associate persons X and Y in the overlapping area on a one-to-one basis.
