SigmaStar's MAC footprint spans two IEEE registrant names that should be aliased to one company: "Sigmastar Technology Ltd." (4 blocks, about 67.1 million addresses) and "Xiamen Sigmastar Technology Ltd." (2 blocks, about 17.8 million addresses), registered at 15th Floor, Unit A, Chuangxin Building, Software Park, Xiamen Torch Hi-Tech Industrial Development Zone, Xiamen, Fujian, China. Verified samples include 00:9D:85, 14:C9:CF, 50:7B:91, and D0:7C:B2 (Sigmastar Technology Ltd.) plus 24:14:07 (Xiamen Sigmastar). SigmaStar was established in 2017 with a team originating from MStar Semiconductor's smart-camera business — MStar was acquired by MediaTek in 2012 — and MediaTek holds a 28.8% stake (Shenzhen ticker 301536). Its silicon spans surveillance/IP-camera SoCs (extremely common in budget IP cameras, dashcams, and video doorbells), AIoT/edge-AI SoCs, and smart-display/HMI SoCs, with roughly a 36.6% global share of surveillance-camera ICs and about 80% of revenue from camera chips. The key analyst point is the chipset pattern: a SigmaStar OUI identifies a device built on a SigmaStar camera/AIoT SoC regardless of the brand on the box. For triage, a SigmaStar OUI on a camera VLAN almost certainly means a budget IP camera, doorbell, or dashcam — classify it as surveillance/IoT and segregate it, since the brand label may be generic and firmware support is often poor.

- Special note
- Chipset-OUI flag. A SigmaStar OUI identifies a device built on a SigmaStar camera/AIoT SoC regardless of brand. The two registrant names are the same company — alias them; distinguish SigmaStar from its MStar/MediaTek ancestry. The IEEE registry publishes no assignment dates, so none is stated here.

- Analyst note
- A SigmaStar OUI on a camera VLAN almost certainly means a budget IP camera/doorbell/dashcam — classify as surveillance/IoT and segregate it, since the brand label may be generic and firmware update support is often poor.
