About this vendor.

Updated  ·  Confidence: Medium-High

Qingdao Intelligent&Precise Electronics Co.,Ltd. is a Chinese OEM/ODM that holds 21 IEEE MA-L (OUI-24) blocks, all registered to the same address at No. 218 Qianwangang Road in the Qingdao Economic & Technological Development Zone, Shandong, China. The company is not a consumer brand: its products are internally embedded Wi-Fi/Bluetooth combo wireless modules built for integration into smart TVs and other connected consumer electronics rather than sold standalone. FCC modular-approval filings under grantee code 2AJVQ confirm this profile, with the modules' best-documented use case being wireless connectivity inside smart TVs (Hisense is cited as a known customer by several secondary sources). Older filings also cover USB 802.11 b/g/n WLAN dongles and PCBA optoelectronic control components. The practical takeaway for network operators: a MAC address from one of these OUIs on a home or enterprise network almost always belongs to a smart TV or similar connected appliance, not a phone or computer. No CVEs, advisories, or threat-intelligence hits are attributed to this vendor or its blocks, so the security-relevant null here is sourced and honest rather than an absence of looking. Two data caveats apply: the IEEE registry spells the province "Shangdong" (a likely typo for "Shandong," reproduced verbatim from the source), and IEEE publishes no registration dates — the per-block dates that third-party trackers show are database artifacts, not IEEE facts.

IEEE assignment
21 prefixes → Qingdao Intelligent&Precise Electronics Co.,Ltd. [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv); cross-confirmed maclookup.app
Registry / block size
MA-L (24-bit OUI; 16,777,216 addresses per block); holds 21 IEEE prefixes [Confirmed] — enrichment/registries/oui.csv. NOTE: IEEE's public OUI data publishes NO assignment/registration date (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools (maclookup.app shows per-block dates spanning 2018-07-22 to 2026-04-01) is a database artifact, not an IEEE fact.
HQ / country
No. 218 Qianwangang Road, Qingdao Economic & Technological Development Zone, Shandong 266510, CN [Confirmed] — IEEE MA-L (registry spells province "Shangdong" [sic]); address form cross-confirmed maclookup.app, udger.com
Company status
active OEM/ODM; founded ~2014 [Likely — founding year and "active" status from secondary trade sources, no official registry] — globalsources.com, bbs.fobshanghai.com
Device types
Wi-Fi/Bluetooth combo wireless modules (internally embedded, modular FCC approval) for smart TVs and connected consumer electronics; older filings cover USB 802.11 b/g/n WLAN dongles and PCBA optoelectronic control components [Confirmed] — fccid.io/2AJVQ, fcc.report
Notable products / customer
embedded Wi-Fi/BT modules; Hisense cited as a known customer [Likely — single-angle web sourcing] — fccinsights.com, device.report
FCC grantee code
2AJVQ [Confirmed] — fccid.io/2AJVQ, fcc.report
FCC filing volume
~35–54 device IDs since 2016 (count varies by source: fcc.report ~35; fccid.io ~54) [Likely — sources disagree, range stated] — fccid.io/2AJVQ, fcc.report
Verified sample prefixes (all MA-L)
10:B2:32, E8:51:77, 10:C7:53, C0:E5:DA, D4:0A:DC [Confirmed] — enrichment/registries/oui.csv; full 21-block list in JSON
MA-M / MA-S registry
none — no entry in mam.csv or oui36.csv for this exact vendor [Confirmed] — enrichment/registries/mam.csv, oui36.csv. Data trap: a "Qingdao Intelligent" hit in mam.csv is a DIFFERENT entity (Qingdao Goertek Intelligent Sensor Co.,Ltd, OUI C4:CC:37, MA-M) — not this vendor.
Website
Unknown — no official corporate website found in search or third-party database entries [Unknown]
Security context
no CVEs, advisories, malware campaigns, or known exploits attributed to this vendor or its OUI blocks; general embedded-Wi-Fi-module supply-chain/firmware considerations apply but no vendor-specific incidents are documented [Confirmed — sourced null]
IANA Reference
blank — no IANA RFC applies to this OUI entry type [Unknown / N/A]
Analyst note
a MAC from one of these OUIs is almost certainly an embedded module inside a smart TV or connected appliance (Hisense and similar Chinese-brand consumer electronics), not a standalone computer or phone; no evidence of industrial-control, surveillance, or high-risk IoT use.
