The supplier reports ISO 9001, ISO 14001, OHSAS/OHSMS 18001, and GMP certifications, five production lines, 11–20 R&D engineers, 21–30 quality-control staff, and conference-system output of 100,000 pieces. Its stated services include system design, installation, troubleshooting, user training, and technical support. Export activity is documented since 2015, with 51%–70% of sales from exports.

This directly supports its status as a product manufacturer rather than only a trading company.

After-Sales capabilityThe supplier states that staff support customers throughout system purchase, installation, on-site troubleshooting, and training on equipment use after installation. This is explicit evidence of comprehensive technical and user-support services.

R&D capabilityThe supplier describes itself as a high-tech enterprise with its own brand and dedicated R&D, production, and sales functions, focused on high-performance and innovative audio-video products. It also reports 11–20 years of combined R&D engineer experience, supporting an innovation capability assessment.
