Direct peers

• Moxa Inc. Moxa is a direct peer in industrial serial connectivity (RS232/422/485, serial-to-Ethernet servers, industrial network switches) — highly comparable to DTECH's industrial serial and Ethernet-to-serial product lines serving factory automation and industrial IoT customers.
• Adder Technology: Adder is a direct peer in KVM and high-performance AV extension over IP and fiber — directly comparable to DTECH's KVM extender and HDMI fiber optic extender products serving enterprise and broadcast customers.
• StarTech.com: StarTech.com is a direct competitor in IT and AV connectivity, offering an overlapping product portfolio of HDMI cables, splitters, extenders, KVMs, serial converters, and fiber optic solutions sold through B2B channels — highly comparable in product breadth and target customer base to DTECH.
• C2G (Legrand AV): C2G (formerly Cables To Go, part of Legrand AV) is a direct peer focused on AV cables, adapters, splitters, and extenders sold through B2B distribution — directly overlapping with DTECH's HDMI/VGA/DVI cable and signal distribution categories.
• ATEN International: ATEN is a Taiwan-based specialist in KVM extenders, AV splitters/extenders, and serial/USB connectivity — closely overlapping with DTECH's extender series, KVM products, and industrial serial converters, with similar OEM/ODM-style global distribution.
• Black Box Corporation: Black Box is a direct peer in KVM extension, AV signal distribution, and industrial connectivity — comparable in serving both enterprise AV installations and industrial serial networking customers.

Broad incumbents

• Crestron Electronics: Crestron is a broad incumbent in pro AV control, signal distribution, and room AV — competing with DTECH's pro-AV signal distribution portfolio as part of a much larger integrated AV control offering.
• Belkin International: Belkin is a broad incumbent in consumer and prosumer AV/IT connectivity — HDMI cables, USB-C adapters, KVMs, and docks — overlapping DTECH's consumer AV line but with stronger global consumer brand recognition.
• Extron Electronics: Extron is a broad incumbent in pro AV signal processing, distribution, extension, and control — competing with DTECH's pro-AV splitter/extender/converter lines at the higher-end of the professional installation market.
• Tripp Lite (Eaton): Tripp Lite (now part of Eaton) is a broad incumbent offering HDMI cables, splitters, extenders, KVMs, and industrial connectivity as part of a much wider power and IT infrastructure portfolio — competes with DTECH in AV/IT cables but with far broader scope and brand reach.
