About Us

Si-Jung is a company that develops, manufactures and sells next-generation visibility meter to complement the shortcomings of the current visibility meter and maximize its advantages.  The main products are the optical visibility system and the image analysis system. In case of the optical system, it complements the parts which were difficult to install due to the long installation length. In the case of the image analysis system, we are developing a prototype, and we are currently piloting it. We want to be a leading company in the visibility meter based on our unique technology.
