PURPOSE: A system device measuring horizontal and vertical displacement by photographing one or more target images is provided to automatically measure a partial or whole change of a structure depending on the selection of a target installing position and to prevent accidents by generating a safety alert caused by the rapid change through a change analysis of the structure. CONSTITUTION: A system device measuring horizontal and vertical displacement by photographing one or more target images comprises an illuminance sensor measurement circuit(105), an LED lighting control circuit(106), an cable transceiver circuit(103), a wireless transceiver circuit(104), a watchdog and main control circuit having a power reset function, and a battery and power circuit for power failure. The system device comprises a circuit measuring a coordination change of X and Y axes of a gyro sensor, a fan tilt motor control circuit of an image acquisition device, a camera communication control matching circuit, a setting data memory storage circuit of the image acquisition device, and a liquid crystal display circuit for the operation verification of the image acquisition device. The system device comprises an operation button input circuit for operating and manipulating the image acquisition device, the wireless transmission and reception circuit, the on-line transmission and reception circuit, a microprocessor and watch dog of the image acquisition device and a main control unit circuit having the power resetting function, and an integrated controlling device. The integrated controlling device controls and manages a series of operation.
