The present invention relates to video data transmitting apparatus using for metallic body, comprising: an observation camera part in which is transmitted through metallic body of a motor such as automobile, ship, aircraft, and etc. to amplify modulated signal by wideband RF (Radio Frequency) amplifier, the modulated signal in which is modulated as PM (Phase Modulation) by PLL (Phase Locked Loop) process for sound and video signal inputted from mike and camera, the mike and the camera is run using by motive power for electronic power of automobile itself; and a camera control part in which outputs through audio and video output after amplifying modulated signal as stabilized level, the modulated signal in which is modulated as PM by stabilized PLL process, the stabilized PLL process in which is stabilized and amplified output of transmitted sound and video signal through the metallic body of the motor for camera shooting from the observation camera. Therefore, the present invention provides simple installation and high performance of stable transmission rate because it is not connecting with wires separately but directly connecting to metallic body for receiving sound and video signal as transmitting through metallic body for transmission of sound and video signal of from mike and camera, and to provide of high definition screen for camera shooting as transmitting wideband signal to apply phase modulation process to be modulated phase by stabilized PLL process as not to be emitted necessary spurious radiation power to outside.
