Our advantage
1. With a professional qualification and experienced expert technical team, we can provide you with professional consultation and services.
2. Have advanced laboratory equipment to ensure the accuracy and reliability of test data.
3. As a third-party testing and certification organization trusted by customers worldwide, we are your certificate of quality.
SRRC certification is one of the necessary conditions for products to enter the Chinese market for sale. It ensures that the wireless transmission characteristics of the wireless camera comply with national standards, avoiding communication problems caused by radio interference and ensuring the legality and compliance of the product.
FCC certification is a mandatory requirement for wireless device certification in the US market. Through FCC ID certification, wireless microphones can prove their compliance with US radio transmission standards, avoiding market bans or fines for violations. This is particularly important for products that hope to be sold in the US market.
KC certification ensures that products comply with relevant laws, regulations, and safety standards in South Korea, and is a necessary condition for smart door lock products to enter the South Korean market. KC certification covers wireless radio frequency, electromagnetic compatibility, and electromagnetic exposure. Strict testing and evaluation are required to obtain KC certification before products can be legally sold in the Korean market and gain consumer trust.
