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.

Device types

AI vision / edge-AI devices — secondary sources describe applications in pan-surveillance (general CCTV/IP camera class), smart wearables, smart home, and live-streaming/media; consistent with networked edge-AI boxes, IP cameras, or smart wearable/IoT modules embedding Wi-Fi. No specific model numbers confirmed from a primary source. [Likely] — authlot.aiwinn.com, aiwinn.com (connection-refused at fetch; described via indexed secondary sources)

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. [Confirmed] — aiwinntech.com/about, aiwin.com.tw, maclookup.app/macaddress/78444A

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.
