AI-Powered supplier vetting
SummaryYilin (Ningbo) Electronics Ltd. is a China-based limited company established in 2002, with 46 employees and three production lines. Its stated business covers manufacturing and processing of microphones, sound products, lamps, and infrared alarms, with offered products including doorbells, night lights, electrical products, alarms, microphones, and mosquito control products. The supplier documents written procedures and records for service assessment, corrective and preventive actions, and complaint handling. However, it reports no management-system certifications, no available SDK, no ODM service, no overseas warehouse, showroom, agents, or branches, and no offline trade-show participation. Customization from samples, designs, minor customization, and flexible customization is available, but no new products were developed in the past year.

CertificationsThe supplier’s certification field is explicitly recorded as “NIL,” indicating that no supplier management-system certification is reported in the provided information.
After-Sales capabilityThe supplier has written procedures and followed records for service assessment, corrective and preventive actions, and customer complaints. However, it has no overseas warehouse, showroom, agents, or branches; service proximity is listed near Ningbo and Shanghai ports, and overseas service coverage is recorded as zero.
R&D capabilityThe supplier reports no available SDK, no new products in the past year, no ODM service, and three years of total R&D-engineer experience. These records indicate limited demonstrated innovation activity, despite offering several forms of customization.
Production capacityThe supplier reports three production lines, 6–10 quality-control staff, manufacturing-related business scope, and normal-order delivery of 20–40 days, with stock-product shipment stated at 1–3 days. These explicit capabilities support a positive assessment of production capacity, although no output volume or capacity-utilization data is provided.
Customization capabilityThe supplier explicitly offers customization from samples, designs, minor customization, and flexible customization, and states that it accepts OEM products. It does not offer ODM services and reports no OEM work for popular brands, so the evidence supports customization but not broader design-development capability.
Product Q&A
Q:What is the wireless transmission range?
A:
Window detectors have a range of 40 meters, while PIR motion detectors have a range of 80 meters.
Q:How does the alarm distinguish between channels?
A:
The receiver uses 5 LEDs to indicate the active channel and emits a unique number of sound pulses (1 to 5) corresponding to the channel.
Q:Can I adjust the alarm volume?
A:
Yes, the receiver features a sound level switch to select between loud and weak alarm volumes.
Q:What happens if the same signal is detected repeatedly?
A:
If a repeat signal is detected on the same channel within one hour, the system will ignore it to prevent unnecessary alarms.
Q:What batteries are required for the system?
A:
The system requires 3 C batteries for the receiver, 3 AA batteries for the motion detectors, and 3 AAA batteries for the window detectors.
