AI-Powered supplier vetting

SummaryThe supplier operates in the research, development, production, and sales of digital, electronic, and communication products. It reports R&D activity, six R&D engineers, ODM and broad customization services, written quality and service procedures, and product and management certifications including FCC, RoHS, CE, and ISO9001:2015. Production-related evidence includes finished-product inspection instructions, four quality-control testing equipment units, and two quality-control staff, but no clear output quantities are provided. The supplier supports OEM services for well-known brands, while no Fortune 500 cooperation is reported. Overseas service infrastructure is limited: it has no overseas warehouse, showroom, agent, or branch, and reports zero countries served overseas. Financial records are referenced for recent years, but the slices do not provide sufficient financial performance evidence for a credibility judgment.

Supplier typeThe supplier’s licensed business scope covers the research and development, production, and sales of digital products, electronic products, and communication products, subject to applicable approvals. This identifies it as an electronics and communications product manufacturer and developer rather than only a trading or service entity.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and FCC, RoHS, and CE product compliance certifications. These certifications provide explicit evidence of formal quality management and stated product compliance coverage.

After-Sales capabilityThe supplier has six R&D engineers whose responsibilities include technical support for production and after-sales service, plus written procedures and records for complaint handling and corrective/preventive actions. However, it has no overseas warehouse, showroom, agent, or branch and reports zero countries offering overseas services, indicating documented support capability but limited overseas service infrastructure.

R&D capabilityThe supplier reports new products during the past year, ODM service, six R&D engineers, and responsibilities covering customer requirements, technical support, and new product development. It lacks an available SDK, but the stated R&D activity and staffing provide positive evidence of product-development capability.

Production capacityThe supplier lists product categories including USB cables, PoE splitters, LoRa transmitters, and KVM switches, along with multiple facility types and standardized finished-product inspection instructions. Two quality-control staff and four testing-equipment units are reported, but no numerical production capacity is supplied, so scale cannot be assessed.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM availability, providing direct evidence of broad customization and design-support capability.

Client casesThe supplier states that it provides OEM services for well-known brands, which is evidence of at least some recognized-brand customer experience. However, it reports no cooperation with Fortune 500 companies and provides no named customers, project details, or verifiable case descriptions, so the depth of its customer case record is limited.

Product Q&A

Q:Why the direct one to one connection cannot be used?

You must use a super Cat5 / 6e network cable (wire sequence T-568B), please check if the addresses of the DIP switches of the transmitter and receiver match

Q:What should I do if 'Check input signal' appears on the screen?

The input signal is inaccessible, please check if the source of the HDMI input signal is connected normally. It is recommended to replace the shorter HDMI cable. Input signal recommended within 5 meters.

Q:What does 'Searching Tx' mean on the screen?

The network cable is partially disconnected, please check if the network cable is normal. It is recommended to use Super Category 5 and Category 6 network cables.

Q:How many receivers can one transmitter support?

Source content can be transmitted from one transmitter to several receivers, supporting up to 253 receivers over LAN.

Q:What is the maximum transmission distance?

The product can extend the full HD HDMI signal to 120 meters with a single cable, or up to 20KM with a Fiber-Optic converter.
