Abstract: Aimed at field operation such as oil field and gas well，a monitoring aptitude system is designed and USB camera
is used for image acquisition to set up embedded video monitoring system for dynamic monitoring.Alarm and control signals of dynamic images are obtained by using dynamic image analysis and processing technologies，and real-time video images are transmitted on-line.This system is fastly responsed，which is lower than 100ms；high-precision with the dynamic
image area less than 1% of background region；the fire hazard inspection is realized by images，which constitutes a multifunction monitor system that can be used in remote monitoring for fire and the environment，it is operated with the temperature sensors so that reduces the false alarm rate greatly.Experiment shows that this system is simple，relocated
easily and wide-range applicability.
