PURPOSE: A real time image confirming device using a smart phone is provided to confirm a digital image signal in a host device or a smart phone connected through a USB interface and to store the image signal in a buffer through a USB PHY of a USB transmission controller. CONSTITUTION: A wireless smart phone image confirming device (40) receives an image signal outputted through a coaxial cable (3) from a CCTV camera (1) and inputs and outputs a control signal to the CCTV camera through an RS-485 interface (2) while converting and processing the image signal. A wireless LAN PHY (45) of a wireless LAN controller (44) controls the wireless LAN controller to transmit a finally converted digital image signal to a host device or to load the same in a video container for image streaming. The digital image signal is transmitted to the host device or a smart phone through Ethernet (46) in the LAN PHY.
