This FCC/CE approved your unit utilizes FM signal modulation to deliver high-quality video and audio. It enhances its quality by utilizing the state-of-the-art circular polarized high gain bi-directional receiving/transmitting antennas. This causes less interruption from unwanted signals and delivers high-quality video and audio. Maximum Performance: Flat and horizontal surface should be used for preventing this product to fall or tilt. For quality video/audio, the maximum transmission range is 300 feet. All obstacles from TV, other wireless products and steel structures should be avoided between camera and receiver. If interference occurs, please relocate or redirect the equipments till performance is improved. Avoid directing the camera at light fixtures or extreme sunlight as it will interfere with providing a quality image. Always keep lens clean to get quality video. The door phone and camera are weatherproof designed but not waterproof. They are not supposed to place in water or moist place for long time, otherwise it will shorten the product’s life.

FCC ID: T8NDIT001 Page 2 of 10 TEST PROCEDURE GENERAL: This report shall NOT be reproduced except in full without the written approval of SHENZHEN MOST ELECTRONICS CO., LTD. The EUT was transmitting a test signal during the testing. POWER LINE CONDUCTED INTERFERENCE: The test procedure used was ANSI Standard C63.4-2003 using a 50H LISN. Both Lines were observed. The bandwidth of the receiver was 10kHz with an appropriate sweep speed. The ambient temperature of the EUT was 25 with a humidity of 58%. RADIATION INTERFERENCE: The test procedure used was ANSI Standard C63.4-2003 using a ANRITSU spectrum analyzer with a pre-selector. The analyzer was calibrated in dB above a micro volt at the output of the antenna. The resolution bandwidth was 100 kHz and the video bandwidth was 300 kHz up to 1 GHz and 1 MHz with a video BW of 3 MHz above 1 GHz. The ambient temperature of the EUT was 25 with a humidity of 58%. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was established by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor supplied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the Pre-selector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) METER READING + ACF = FS 33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m ANSI STANDARD C63.4-2003 10.1.7 MEASUREMENT PROCEDURES: The EUT was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The EUT was placed in the center of the table (1.5m side). The table used for radiated measurements is capable of continuous rotation. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1m to 4m. The antenna was placed in both the horizontal and vertical planes. The situation was similar for the conducted measurement except that the table did not rotate. The EUT was setup as described in ANSI Standard C63.4-2003 10.1.7 with the EUT 40 cm from the vertical ground wall. SHENZHEN MOST ELECTRONICS CO., LTD.
