Shenzhen Aiwinn information Technology Co., Ltd. — 78:44:4A (MA-L)

OUI 78:44:4A is an IEEE MA-L block registered to Shenzhen Aiwinn information Technology Co., Ltd., a company based in Nanshan district, Shenzhen, Guangdong, China. The registry address — Room 1001, 10th floor, Building G3, TCL International E city, Shuguang community, Xili street — places it among the mid-tier tech tenants of a major Shenzhen technology cluster. Secondary sources describe Aiwinn as an AI vision algorithm and edge-AI solutions provider (branded 芯算一体, "integrated chip and algorithm"), with application domains spanning pan-surveillance, smart wearables, smart home, and live-streaming media. The device class most consistent with that profile is networked edge-AI boxes, IP cameras, or smart wearable/IoT modules embedding Wi-Fi — not a consumer router or PC brand — though no specific model numbers were confirmed from a primary source. The vendor's own site (aiwinn.com) was connection-refused at fetch time, so product detail rests on indexed secondary sources. A name-disambiguation caveat matters here: "Aiwinn Technology Sdn Bhd" (Kuala Lumpur, Malaysia, aiwinntech.com) and "AIWin Technology Co., Ltd." (Taiwan) are distinct, unrelated companies; only the Shenzhen CN registrant owns this OUI. As with any OUI/MAC prefix, IEEE publishes no registration date — a "2021-07-08" date appearing in third-party MAC databases is a database artifact, not an IEEE fact.

Name disambiguation

Three distinct entities share similar names — (1) Shenzhen Aiwinn information Technology Co., Ltd. (the OUI registrant at 78:44:4A, Shenzhen CN, edge-AI/IoT); (2) Aiwinn Technology Sdn Bhd (Kuala Lumpur, Malaysia, aiwinntech.com, est. Aug 2020, smart-city/enforcement equipment — bodycams, night-vision, body armor — with Chinese OEM partners); (3) AIWin Technology Co., Ltd. (Taiwan, aiwin.com.tw, unrelated). This OUI maps to entity (1) only.

Security context

No CVEs, CISA KEV entries, or public exploit disclosures found for Shenzhen Aiwinn or its products. General note: the surveillance/pan-CCTV device category this vendor's applications fall into is a known IoT security-risk class (default credentials, infrequent firmware updates, weak/absent encryption are common). No threat intelligence found linking OUI 78:44:4A devices to active exploitation or supply-chain compromise. The Malaysia-based Aiwinn Technology Sdn Bhd (distinct entity) lists Chinese military-adjacent OEM partners — relevant background only if a user encounters an aiwinntech.com device, NOT applicable to this OUI registrant.

Analyst note

The single 78:44:4A MA-L block reliably identifies genuine Shenzhen Aiwinn hardware on a globally-administered address; given the edge-AI/IoT device class, treat such devices per standard IoT-segmentation and credential-hygiene practice. Do not conflate with the unrelated Malaysia or Taiwan "Aiwin(n)" companies.
