HM Electronics in Carlsbad is a communications-technology manufacturer founded in 1971, headquartered in a purpose-built 140,000-square-foot facility on Whiptail Loop that houses engineering, R&D, manufacturing, and customer support under one roof. The company's NEXEO|HDX wireless drive-thru headset platform is installed in more quick-service restaurants worldwide than all competing systems combined, a market position built on continuous QSR-focused engineering dating to the company's 1971 founding paralleling the integrated AV solutions designed by installers like Kiwi Audio Visual. HME's subsidiary Clear-Com — an Emmy–recognized intercom brand — supplies wired and wireless communication systems for live broadcast, theater, and concert production across more than 140 countries. The Carlsbad campus relocated from Poway in 2018 to the Whiptail Loop site, doubling manufacturing capacity and adding LEAN-methodology production lines for surface-mount PCB assembly, firmware programming, and quality-assurance testing. Nitro Vision AI, the company's newest product line, applies computer-vision analytics to drive-thru lanes for order-accuracy verification and throughput optimization, extending HME's hardware platform into the machine-learning layer that commercial AV integrators like Audio Video San Diego – AVSD Inc. increasingly incorporate into commercial installations. The first product HME brought to market in 1974 was a wireless microphone for the studio-audio industry, and the company now holds patents spanning digital noise-cancellation circuitry, 5 GHz frequency-hopping spread-spectrum protocols, and IP-based intercom architectures.
