rotate the lens ring until it clear. For auto focus webcam, please wave your hand in
front of the webcam ,it will adjust the focus automatically.
3). The lens is dirty; please use a dedicated cleaning cloth wetted with alcohol to
scrub its surface carefully.

the camera.
5).Your video communication application does not support H.264 compression or
does not support HD video calls;
7.Local preview image is lagging, image tailing and frame interruption
1).The encoding format of the video-previewing software has been set as YUV or
YUY2, and thus high-definition images cannot be transferred through USB2.0 cables;
please change the encoding format to H.264 or MJPEG encoding in the
video-previewing software (e.g. Amcap);
2).An overlong USB extension cable (it should be noted that the sum of the lengths of
the extension cable and the USB cable is less than or equal to three meters) of poor
quality is used together with a nonstandard USB2.0 port (USB ports of some laptop
computers or front USB ports of some computer cases are of USB1.1 standards),
which defies transferring of high-definition images;
