We started in 1995 under the name of SJ Corporation as a sales company of CCTV products with outsourcing from OEM subcontractors.

Since our establishment, we have been pursuing a goal to be a leading supplier in this field by tackling unceasing challenge and by devoting consistent effort to be a customer-friendly supplier of various CCTV products by creating new value of innovation.

As a token of this goal, we set up in 1997 our own manufacturing facility to add our capacity along with OEM subcontractors to provide better services for a "one-stop-shopping" for domestic and overseas customers.

In 1999, SJ Corporation was reborn as SJ Microtech Co., Ltd., and In 2004, was relocated to a new facility in the vicinity of Seoul, Korea.

SJ Microtech Co., Ltd., is always thinking ahead of future market trend, and is investing our resourses for R&D to keep up with it under the motto of " Simple and Easy Installation".
