Standard Form Sample Request for Confidentiality Letter MS-0044715 Page 1 of 1 Revision 0 The following is a sample Confidentiality Request letter, which needs to be completed on company letterhead, signed by an authorized Applicant/Agent, and submitted to TÜV Rheinland. Date: _2022.3.21__ Subject: Confidentiality Request for FCC ID: _SVN-LCH86 Pursuant to FCC 47 CRF 0.457(d) and 0.459 and IC RSP-100, Section 10, the applicant requests that a part of the subject FCC/IC application be held confidential. Type of Confidentiality Requested Exhibit Short Term Permanent Block Diagrams Short Term Permanent Internal Photos *** Short Term Permanent Operation Description/Theory of Operation Short Term Permanent Tune-Up Procedure Short Term Permanent Schematics Short Term Permanent User’s Manual*** Short Term Permanent BOM Short Term Permanent PCB Layout Short Term n/a Test Setup Short Term n/a External Photos _Zhejiang Dahua Vision Technology Co., Ltd_ has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Permanent Confidentiality: The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. (*** PAG only) Short-Term Confidentiality: The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of _180_ days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify TUV Rheinland in the event information regarding the product or the product is made available to the public. TUV Rheinland will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04-1705.

Safety Human Exposure 1.1 Radio Frequency Exposure Compliance 1.1.1 Electromagnetic Fields RESULT: Pass Test Specification Test item : Smart interactive whiteboard Identification / Type No. : DHI-LCH86-MC410-B FCC ID : SVN-LCH86 Test standard : CFR47 FCC Part 2: Section 2.1091 CFR47 FCC Part 1: Section 1.1310 FCC KDB Publication 447498 v06 FCC KDB Publication 865664 D01 v01r04 FCC KDB Publication 865664 D02 v01r02  Product Classification This device defined as a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at 20 cm is normally maintained between the transmitter's radiating structure(s) and the body of the user or nearby persons. Max 5.14 dBi for 2.4GHz Wi-Fi, Max 4.69 dBi for 5GHz Wi-Fi  Radio Frequency Exposure Limit For FCC: Frequency range (MHz) Electric field strength (V/m) Magnetic field strength (A/m) Power density (mW/cm²) 300-1,500 -- -- f/1500 1,500-100,000 -- -- 1.0 For IC:  Radio Frequency Exposure Calculation Formula a) EUT RF Exposure Evaluation standalone operations Mode *Measured RF Output Power (dBm) Antenna Gain (dBi) Distance (cm) Power Density (mW/cm²) FCC Limit (mW/cm²) 2.4G Wi-Fi 24.06 5.14 20 0.166 1.0 5G Wi-Fi 20.94 4.69 20 0.073 1.0 Note: 1. *2.4GHz Band RF Output Power: Refer CN22GK21 001 Appendix B 2. *5GHz Bands RF Output Power: Refer CN22GK21 002 Appendix B b) Simultaneous transmission MPE: Per KDB 447498 D01 v06, simultaneous transmission MPE test exclusion applies when the sum of the MPE ratios for all simultaneous transmitting antennas incorporated in a host device, based on calculated or measured field strengths or power density, is ≤ 1.0. Simultaneous transmission Scenarios No. Simultaneous transmission Scenarios 1 2.4GHz Wi-Fi 2 5GHz Wi-Fi 1) For 2.4GHz Wi-Fi: The MPE ratio for 2.4GHz WiFi can be calculated as follow: =The power density at 20cm distance/MPE limit =0.166 mW/cm²/1 mW/cm² =0.166 2) For 5GHz Wi-Fi: The MPE ratio for 5GHz WiFi can be calculated as follow: =The power density at 20cm distance/MPE limit =0.073 mW/cm²/1 mW/cm² =0.073 The sum of the MPE ratios for all simultaneous transmitting antennas: =0.166+0.073 = 0.239<1.0 As the sum of MPE ratios for all simultaneous transmitting antennas is ≤ 1.0, simultaneous transmission MPE test exclusion will be applied.  Conclusion Therefore the maximum calculations result of above are meet the requirement of Radio Frequency Exposure (MPE) limit.
