Image Rotated: Select the screen display “flip”, “mirror”, or “flip + mirror.
Video clip format: Select RECORDING compression format H.264、MPEG-4、MJPEG、3GPP .
 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.
 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).
 MJPEG : Motion JPEG stream uses considerable amounts of bandwidth, but provides excellent image
quality and access to every image contained in the stream.
