AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier with broad business activities spanning electronic products, software and hardware, display devices, intelligent robots, new-energy equipment, security systems, and related technical services. It offers extensive customization, including sample-, design-, full-, minor-, and flexible customization, and launched new products during the past year. Quality assurance is reported, but finished-product inspection is random, only one quality inspector is reported, and raw-material traceability is unavailable. The supplier has in-stock capability but no overseas warehouse or showroom. It lacks 3D software design and SDK availability. Financial information supplied shows zero operating revenue, cost, gross profit, and operating profit for the stated periods; no monetary figures are reproduced here. Corrective-action and complaint-handling procedures exist but lack written records. No customer cases or certifications are explicitly provided.

Supplier typeThe supplier is explicitly described as a professional technical supplier and its business scope covers electronic components, software and hardware, display devices, intelligent robots, new-energy equipment, security systems, and technical services. This supports classification as a diversified technology and equipment supplier rather than a narrowly specialized manufacturer.

Financial creditThe supplied financial-capacity record reports zero operating revenue, operating cost, gross profit, and operating profit for the stated periods. These figures provide explicit evidence of very limited reported operating activity, although the slices do not explain the accounting context or independently verify the data.

R&D capabilityThe supplier is identified as having professional technical R&D capability and launched new products during the past year. It also offers broad product customization, but does not provide 3D software design or an available SDK; the company description additionally presents a strategic manufacturing partner with automated production facilities and complete production lines.

Production capacityThe company description states that its display-solutions partner has automated production facilities and complete production lines, and the supplier reports in-stock capability. Nevertheless, outsourcing procedures and manufacturing contracts have unknown status, so the slices support production-related capability but do not fully establish the supplier’s own manufacturing controls.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is repeated across the R&D and design-capability records and is direct evidence of broad customization capability.

Product Q&A

Q:How many channels are available and how does it prevent interference?

The system provides 200 selectable channels within a 54.73MHz bandwidth with 270KHz spacing. It uses UHF band technology and built-in 8 groups of interference-free frequencies to support simultaneous use of multiple units without interference.

Q:What is the battery life and power supply method?

The system is powered by AA batteries. It supports up to 15 hours of operation at low power (3mW) and 10 hours at high power (30mW).

Q:Does the microphone support automatic frequency synchronization?

Yes, it adopts infrared automatic frequency synchronization technology. If frequencies are misaligned, a simple press allows the transmitter to automatically lock and align with the receiver frequency.

Q:What certifications does this product hold?

The product holds CCC certification. Additionally, the company's solutions generally comply with CE, FCC, and RoHS standards for international markets.

Q:Can the microphone be customized or does it support OEM/ODM?
