Bosch's security/safety hardware is separable from the general Bosch corporate registrant, but it spreads across several IEEE strings that an enrichment pipeline should group: "Bosch Security Systems" (Lancaster, PA, US; MA-L plus an MA-M block in Ovar, Portugal), "Bosch Security Systems, Inc." (Fairport, NY, US), and "Bosch Sicherheitssysteme GmbH" (Munich, Germany; one MA-L block), alongside the broader "Robert Bosch GmbH" registrant (Germany) that covers any Bosch product line. A verified MA-L sample for the main string is 00:04:63 ("Bosch Security Systems", Lancaster, PA). An important correction: A4:18:94 is NOT Bosch — it is currently registered to "IQSIGHT B.V." (Eindhoven, Netherlands), the former Bosch video-systems business now under the Keenfinity Group; older Wireshark data still mislabels A4:18:94 as "Bosch Security Systems B.V.", but the raw IEEE Organization Name is IQSIGHT B.V. These Bosch OUIs appear on IP cameras, video surveillance, intrusion/fire alarm panels, access control, and public-address/voice-alarm systems. Bosch is a German company and carries no covered-list restrictions. The recommended scoping is a dedicated Bosch Security entry that cross-links to a general Bosch grouping, because some Bosch security devices may still use the parent "Robert Bosch GmbH" OUI. For triage, a "Bosch Security Systems" OUI indicates surveillance/safety hardware (cameras, alarm/fire/access panels), whereas a bare "Robert Bosch GmbH" OUI could be any Bosch product line.
- IEEE assignment
- "Bosch Security Systems" (00:04:63, Lancaster PA, US; MA-L + an MA-M block in Ovar, Portugal); "Bosch Security Systems, Inc." (00:01:31, Fairport NY, US); "Bosch Sicherheitssysteme GmbH" (30:F0:28, Munich, DE; 1 MA-L block); plus parent "Robert Bosch GmbH" (44:36:59 and others, DE) [Confirmed] — IEEE MA-L / MA-M
- Registry / block size
- MA-L predominant; "Bosch Security Systems" additionally holds an MA-M block (Ovar, Portugal) [Confirmed] — maclookup.app (IEEE-derived). 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" from third-party tools is a database artifact, not an IEEE fact.
- HQ / country
- Germany (Robert Bosch / Bosch Sicherheitssysteme); some security blocks carry US addresses (850 Greenfield Road, Lancaster, PA for "Bosch Security Systems"; 130 Perinton Parkway, Fairport, NY for "Bosch Security Systems, Inc.") [Confirmed] — IEEE MA-L
- Company status
- active; security/safety division of the Robert Bosch group [Confirmed] — maclookup.app
- Device types
- IP cameras, video surveillance, intrusion/fire alarm panels, access control, public-address/voice-alarm [Confirmed] — maclookup.app
- Notable products
- Bosch IP cameras, intrusion/fire panels, access control, PA/voice-alarm
- Verified prefix sample
- 00:04:63 ("Bosch Security Systems", Lancaster PA); 00:01:31 ("Bosch Security Systems, Inc.", Fairport NY); 30:F0:28 ("Bosch Sicherheitssysteme GmbH", Munich); 44:36:59 ("Robert Bosch GmbH", Gerlingen-Schillerhöhe) [Confirmed] — maclookup.app, macvendorlookup.com
- Data-quality correction
- A4:18:94 is NOT Bosch — current IEEE MA-L registrant is "IQSIGHT B.V.", Achtseweg Zuid 173, Eindhoven, NL (former Bosch video-systems business, now Keenfinity Group). Wireshark's legacy "Bosch Security Systems B.V." note is stale. No IEEE registrant string exactly named "Bosch Security Systems BV" exists. [Confirmed] — IEEE MA-L, iqsight.com imprint
- Special note
- Bosch security devices DO have their own registrants (separable from "ROBERT BOSCH GmbH"), but some may still use the parent OUI — group them and cross-link a general Bosch entry. German company, no covered-list restrictions. [Confirmed] — maclookup.app/vendors/bosch-security-systems
- Related vendors
- parent Robert Bosch GmbH
- Analyst note
- A "Bosch Security Systems" OUI indicates surveillance/safety hardware (cameras, alarm/fire/access panels); a bare "Robert Bosch GmbH" OUI could be any Bosch product line. German company, no covered-list restrictions.
