Recommend
  • Network Camera SRRC Certification

    Network Camera SRRC Certification

    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.

  • Wireless microphone FCC ID certification

    Wireless microphone FCC ID certification

    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.

  • Intelligent door lock KC certification

    Intelligent door lock KC certification

    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.
