our story

We Born to Understand
Our Clients

SIH Tech, based in Shenzhen, China, was founded in 2011 with a primary focus on manufacturing power supply products for domestic clients who mainly exported to overseas markets. Despite the challenges, we persevered and established a solid reputation among our clients.

In 2014, we expanded our customer base to include overseas clients. To meet their diverse requirements, we decided to broaden our product range to include audio & video transmission equipment such as multiple video cables, CCTV microphones. Although this was a significant shift for us, we were determined to succeed.

Around the same time, a new technology for high-definition video transmission (HDCVI, TVI, AHD) became increasingly popular. Our clients were asking for HD video balun to complement these new technologies, and we saw an opportunity to fulfill their needs. In 2015, we began producing HD video balun, and we were thrilled to achieve 150k pairs in sales in the first year.

As our business continued to grow, we realized that the use of IP cameras was becoming more widespread. In response, we added PoE switches and accessories to our product portfolio in 2016, enabling us to provide our clients with ways to power and connect their IP cameras.

Today, we are proud to be a one-stop solution provider for security and video surveillance accessories, including power supply and transmission, data transmission, video display, audio and video transmission, RFID/NFC, supplemental lighting and multiple tools. We have come a long way since our establishment in 2011, and we look forward to continuing to provide high-quality products and excellent service to our clients all around the world.
