Requirements for Using Voice, Motion, or Face Recognition Requirements for Using Voice Recognition ●● The voice recognition rate varies depending on the volume/tone, pronunciation, and ambient sound environment (TV sound and ambient noise). Requirements for Using Motion Recognition ●● Before using motion recognition, make sure the TV's camera has been turned on. ●● You should be located between 4.9 ft and 11.5 ft from the camera. The actual recognition range may vary depending on the camera angle and other factors. ●● Motion Control relies on the TV camera and therefore will not function if the camera is pointed up or down. Adjust the camera's position to toward front. Do not point the camera directly at the sun or any other light source or obstruct its view. ●● For the camera to recognize movement, you must stand out from the background. ●● The appropriate ambient brightness is 50 to 500 lux.
