Image Rotated: Select the screen display “flip”, “mirror”, or “flip + mirror.
Video clip format: Select RECORDING compression format H.264、MPEG-4、MJPEG、EZVuu HQ
and EZVuu LQ .
 Profile1(H.264): H.264 provides higher compression rate than MPEG-4. Thus, H.264 can decrease the
bandwidth usage and further apply on 3G. However, H.264 will occupy more system resources than
MPEG-4. As long as the operating system appears operating difficulties under H.264 format, please change
to select MPEG-4.
 Profile2(MPEG-4): MPEG-4 has the advantage of sending a lower volume of date per time unit
across the network (bit-rate) compared to Motion JPEG and therefore provides a relatively high
image quality at a lower bit-rate (bandwidth usage).
 Profile3(MJPEG): Motion JPEG stream uses considerable amounts of bandwidth, but provides
excellent image quality and access to every image contained in the stream.
