        FCC ID certification for dashcams

        Dash cams exported to the US market must pass the FCC ID certification, which is a mandatory compliance threshold for entering the US market. FCC ID certification ensures that the product complies with the regulations of the Federal Communications Commission of the United States for radio wave transmitting equipment, preventing electronic products from interfering with radio communications. The dashcam products produced must comply with FCC PART 15C regulations, prepare the necessary technical documents and conduct corresponding tests. Only after completing the certification process can the FCC ID be marked on the products.

        The main contents of the FCC ID certification test for dash cams

        1. Transmission power: Test whether the power of the radio waves emitted by the equipment is within the allowable range.

        2. Transmission bandwidth: Test whether the bandwidth of the radio waves transmitted by the equipment complies with the regulations.

        3. Power spectral density: The distribution density of the power energy emitted by the test equipment in terms of frequency.

        4. Radiated sideband: The sideband emission of the test signal prevents interference to adjacent frequency bands.

        5. Emission spurious: Test unintended emissions outside the main wave to ensure they do not interfere with other equipment.

        The materials required for applying for FCC ID certification for a dashcam

        First, basic information needs to be prepared. The basic information statement should include the trademark, product name, model, and add a warning statement and FCC ID number. Secondly, all chip models and crystal oscillator information should be clearly marked in the block diagram and circuit schematic diagram. The antenna frequency should also be indispensable. The operation description should summarize the basic working principle of the product circuit and the input and output information, etc. Finally, the FCC ID number must be clearly displayed on the product label. The FCC application form should be filled with the name, address, contact person information and product information of the applying company to ensure accuracy. The FCC authorization letter must be signed and sealed by the contact person and an electronic version should be provided. A confidentiality letter is an agreement signed between the applying company and the TCB institution. Finally, upload clear photos of the product's interior and exterior, and prepare a comprehensive test report to ensure that the product meets the standards.

        The FCC ID certification process for dash cams

        1. Signing a contract: The client signs a consignment testing contract with the testing company, clearly defining the service items and ensuring the rights and interests of all parties.

        2. Application for case opening: The client needs to submit the FCC ID certification request form and test samples to confirm the certification application information.

        3. Sample testing: The laboratory tests each sample item by item in accordance with the standards and prepares relevant materials at the same time, including: circuit schematic diagram, circuit block diagram, circuit description, antenna report, user manual and nameplate identification.

        4. Submit the application: After passing the inspection, the testing company will submit all product information to the TCB certification body authorized by the FCC for review.

        5. Certification by the institution: After an enterprise obtains the FCC certification, it can legally use the FCC mark on its products.

        The cost of FCC certification for dash cams

        The cost of FCC ID certification for dash cams depends on the complexity of the wireless technology specifications supported by the dash CAM. Under the normal basic wireless configuration, the certification fee for wireless products is generally more than 5,000 RMB. If the wireless technology specification of the product is a relatively high configuration, the cost may reach 10,000 RMB or even higher. The specific cost depends on the wireless function of the product and the corresponding test items required. Therefore, the FCC ID certification cost for dash cams can roughly range from several thousand to tens of thousands of yuan. To obtain an accurate quotation, please contact the certification body and provide detailed product information.

        Notes for the first application for FCC ID certification

        For manufacturers applying for FCC ID certification for the first time, they need to register an FCC-FRN with the FCC to establish an application company file. After the TCB review is completed, the certificate issued will have the FCC ID number. Usually, the FCC ID is composed of "Grantee code" and "Product code". Manufacturer code: It is a five-digit number or capital letter, directly assigned by FCC. Product code: Composed of numbers, letters, and "-", but no two or more consecutive "-" can be used. The maximum number of digits in this code does not exceed 14. The customer can customize this number.
