Client Information Applicant : Shenzhen Videotimes Technology Co.,Ltd Address : Room 601, Building B, Union Financial Building Fubao Street, Futian Free Trade Zone, Shenzhen, China Manufacturer : Shenzhen Videotimes Technology Co.,Ltd Address : Room 601, Building B, Union Financial Building Fubao Street, Futian Free Trade Zone, Shenzhen, China 2. General Description of EUT EUT Name : 2.4GHz Digital Wireless Video Baby Camera Models No. : HB88TX Model Different : N/A Product Description : Operation Frequency: 2410MHz~2473MHz RF Output Power: 6.619dBm Antenna Gain: 2dBi Diople Antenna Modulation Type: GFSK (4Mbps) Power Supply : DC Voltage Supply from AC/DC Adapter Power Rating : Adapter (Model:K05V050120U) Input: AC 100-240V~50/60Hz, 0.2A Output: DC 5.0V,1.2A Software Version : V1.0 Hardware Version : HB88T_V02 Remark : The adapter and antenna gain provided by the applicant, the verified for the RF conduction test provided by TOBY test lab. Report No.: TB-MPE174732 Page: 2 of 3 TB-RF-075-1.0 MPE Calculations for WIFI 1. Antenna Gain: Monopole Antenna: 2dBi. 2. EUT Operation Condition: Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 3. Exposure Evaluation: Equation from page 18 of OET Bulletin 65, Edition 97-01 S=(PG)/4πR 2 Where S: power density P: power input to the antenna G: power gain of the antenna in the direction of interest relative to an isotropic radiator. R: distance to the center of radiation of the antenna 4. Test Result: Mode Conducted Power(max) (dBm) Turn-up Power (dB) Max tune up power (dBm) [P] ANT Gain (dBi) [G] Distance (cm) [R] Power Density (mW/ cm 2 ) [S] 2410.0 6.619 6±1 7 2 20 0.00158 2441.5 6.476 6±1 7 2 20 0.00158 2473.0 5.794 6±1 7 2 20 0.00158 Report No.: TB-MPE174732 Page: 3 of 3 TB-RF-075-1.0 5. Conclusion: As specified in Table 1B of 47 CFR 1.1310- Limits for Maximum Permissible Exposure (MPE), Limits for General Population/ Uncontrolled Exposure Frequency Range (MHz) Power density (mW/ cm 2 ) 300-1,500 F/1500 1,500-100,000 1.0 For GFSK:2410~2473 MHz MPE limit S: 1mW/ cm 2 The MPE is calculated as 0.0158mW / cm 2 < limit 1mW / cm 2 . So, RF exposure limit warning or SAR test are not required. The EUT will only be used with a separation of 20cm or greater between the antenna and nearby persons and can therefore be considered a mobile transmitter per 47 CFR2.1091 (b). The RF Exposure Information page from the manual is included here for reference. Note For a more detailed features description, please refer to the RF Test Report. -----END OF REPORT-----
