Techpoint is a fabless semiconductor company that designs and sells mixed-signal ICs for HD video transmission in two markets: security surveillance and automotive. Techpoint's core technology, HD-TVI, converts HD digital video from a camera sensor into an analog signal for transmission over coaxial cable, then converts it back to digital at the receiving end. This approach avoids compression overhead and works over existing coaxial infrastructure, which matters in surveillance installations where replacing cabling is costly. In security surveillance, Techpoint sells transmitter chips for HD cameras and receiver chips for DVRs, with key customers including Hikvision in China. In automotive, Techpoint sells similar ICs for backup cameras, surround-view systems, and in-car displays, targeting automotive OEMs and their tier-1 suppliers. Techpoint sells through independent distributors, but its engineers engage directly with end-customers to win design slots, since those customers specify which chips go into their products. Once a chip is designed in, customers tend to stick with it across product generations, creating some revenue stability. As a fabless company, Techpoint outsources all manufacturing to foundries including TSMC and UMC, keeping capital requirements low but leaving Techpoint exposed to spot pricing risk since it has no long-term foundry pricing agreements. Automotive is the key growth focus—sales cycles run one to three years, but a single design win can span multiple vehicle models, and winning one model can open doors to others.
