Indyme Solutions is registered to MAC prefix 78:8C:4D and 1 more in the IEEE OUI database. When a device's MAC address begins with 78:8C:4D, that block was registered by Indyme Solutions — the OUI identifies the maker of the network hardware, which is not always the brand on the device.

Substantive vendor: identifiable San Diego retail loss-prevention/store-operations company with a coherent product line, two MA-L assignments under the current org string, a legacy-name registration, and a named 2025 industry partnership. No CVEs or abuse reports found.

About this vendor.

Updated  ·  Confidence: Medium

Indyme Solutions, LLC is a San Diego–based retail technology vendor that builds networked in-store hardware for loss prevention and store operations — self-service locked merchandise cases (Freedom Case), sensor-driven deterrence domes (SmartDome), aisle and shelf sensor systems (Smart Sense), and customer-assist call-button systems (SmartResponse) that alert and communicate across in-store systems. Two currently-registered IEEE MA-L blocks map to the "Indyme Solutions, LLC" organization string, both at 8295 Aero Place Ste 260, San Diego: 78-8C-4D and 28-91-76. A third MA-L, 00-0C-59, is registered to "Indyme Electronics, Inc." at a different San Diego address (9085 Aero Dr.) — the company's earlier legal name — and is flagged here as related-but-distinct context, not folded into this vendor's confirmed prefix set. The company describes itself as 30+ years in business with installations across 40,000+ stores, and in January 2025 Sensormatic Solutions (Johnson Controls) announced a partnership to offer select Indyme merchandise-protection products in its own portfolio. The device categories — networked call buttons, sensor domes, locked cases, and alerting endpoints — are consistent with embedded retail hardware carrying its own MAC-assigned NICs, a plausible fit for the multiple small-batch OUI assignments seen over time.

Security / abuse context
no CVEs, exploit disclosures, or abuse/reputation reports found for Indyme devices or the company [Unknown — absence of evidence] — targeted search returned no on-topic security results
Registration date
Unknown [Confirmed absent] — IEEE publishes NO OUI assignment/registration date; the local the IEEE MA-L registry/mam.csv/oui36.csv extracts carry no date column. Any "date registered" on third-party MAC-lookup tools (Wireshark the Wireshark manufacturer database, macvendors.com, maclookup.app) is a database artifact, not an IEEE fact — do not record or attribute one to IEEE.
Analyst note
Substantive vendor, not a bare single-OUI shell — identifiable operating company, coherent product line, two MA-L assignments under the current org string plus a legacy-name registration, and named industry partnership. If the enrichment model is per-OUI rather than per-vendor, the caller should confirm whether 78-8C-4D and 28-91-76 are both recorded here or split into separate OUI entries.
