Dahua holds about 27 MA-L blocks under "Zhejiang Dahua Technology Co., Ltd." plus 4 more under a newer entity, "ZHEJIANG DAHUA TECHNOLOGYCO.,LTD" (note the missing space) — both map to the same vendor. The registered address is No.1199 Waterfront Road (also rendered "BinAn Road"), Hangzhou, Zhejiang, China. Dahua is among the largest video-surveillance manufacturers in the world, generally ranked second to Hikvision. These OUIs appear on IP cameras, NVRs/DVRs, video surveillance, and access control, and many white-label DVRs/cameras are Dahua-based — notably Lorex and Amcrest — while Dahua has used HiSilicon chips (cross-reference the HiSilicon entry). The regulatory context is confirmed and material: Dahua was added to the US Commerce Entity List effective 9 October 2019 (84 FR 54002), is on the FCC Covered List under NDAA Section 889, and is subject to the FCC's November 2022 equipment-authorization prohibition (FCC 22-84, which explicitly addressed rebranded/white-labeled equipment). This is stated as factual regulatory context, not advocacy. For triage, a Dahua OUI — or one of its OEM brands — flags covered/restricted surveillance equipment; treat its appearance on a corporate network as a compliance and shadow-IT signal.
