Hanwha Vision — MA-L prefixes across the Samsung Techwin → Hanwha lineage

Hanwha Vision's MAC footprint spans several registrant strings that trace its name history and must all be aliased to one brand: legacy "Samsung Techwin" blocks, "Hanwha Techwin" (and "Hanwha Techwin Security Vietnam"), and the current "Hanwha Vision" (and "Hanwha Vision VietNam") entities. The company is South Korean, with a Vietnam manufacturing entity that appears as the registrant on some blocks (e.g., Bac Ninh, VN for E4:30:22). These OUIs appear on IP cameras, NVRs, and video surveillance under the Wisenet brand. The corporate history: Samsung Techwin was sold to Hanwha Group in 2015, renamed Hanwha Techwin, then renamed Hanwha Vision in 2023. As a South Korean company, Hanwha is NOT subject to the China-vendor covered-list restrictions affecting Hikvision/Dahua/Uniview. For triage, a Hanwha / Samsung Techwin / Wisenet OUI indicates Korean-origin enterprise surveillance — a non-restricted alternative — and enrichment must alias all three name eras (plus the Vietnam manufacturing entities) to the Hanwha Vision brand.
