AI-Powered supplier vetting

SummaryThe supplier is a Changsha-based limited company in Asia, focused on sensor products including millimeter-wave, vehicle, traffic, industrial, security, altimeter, and obstacle-avoidance radar. It reports 169 employees, assembly-line and SMT facilities, valid manufacturing contracts with associated subcontractors, in-stock capability, and 100% finished-product inspection. The supplier provides broad customization and ODM/OEM services, has introduced new products within the past year, and maintains documented procedures for service assessment, corrective actions, and complaint handling. However, no SDK is available, and the records do not provide certification details. Overseas warehouse and showroom capabilities are absent. Financial information is present only as year labels without usable financial performance details, so financial credibility cannot be assessed from the supplied evidence.

Supplier typeThe supplier is a limited company with a combined company type, operates from Changsha in Asia, and reports 169 employees. Its stated product scope is sensors, with multiple radar product categories listed, indicating a specialized radar and sensing supplier rather than a general trading entity.

After-Sales capabilityThe supplier has written and followed procedures for service assessment, corrective and preventive actions, and customer complaint handling. It also reports in-stock capability and lead times of within 15 working days during the off-season and one month during peak season, but it has no overseas warehouse or showroom.

R&D capabilityThe supplier reports R&D capability, new products within the past year, and ODM service availability. However, it explicitly reports that no SDK is available, which limits the documented software-development support associated with its R&D offering.

Production capacityProduction-related evidence includes assembly-line and SMT facilities, five quality assurance and quality control inspectors, 100% finished-product inspection, raw-material traceability, valid contracts with associated subcontractors, in-stock capability, and 169 employees. These records explicitly support established manufacturing and quality-control capability.

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

Client casesThe supplier reports OEM service for well-known brands, and one buyer name and one trade transaction are listed in the supplied trade record. The evidence confirms some customer or transaction references, but it does not provide enough detail to evaluate the scale, duration, or success of customer cases.

Product Q&A

Q:What are the available firmware versions for TSR20?

Type A supports RS232 for host communication with RS485 output, while Type B supports RS485 for host communication with RS232 output. Cross-flashing is prohibited.

Q:What is the speed measurement range?

The upper limit is 200 km/h (hardware-limited) and the lower limit is 5 km/h (configurable).

Q:Can the radar detect pedestrians indoors?

Multipath interference in indoor environments may cause directional filter anomalies, but field deployments typically do not exhibit such issues.

Q:How can false positives from wind-blown debris be mitigated?

False positives can be mitigated by raising the minimum speed threshold.

Q:What is the refresh rate of the radar?

The radar has a refresh rate of 20ms.
