Video

„Text on video" The text appears in the black bar above the video window with a timestamp. This
timestamp (date and time) is supplied by the security network camera, and the date and time are supplied by
an integrated realtime clock.
„Color" Selects between colour and monochrome display.
„Size" Five options are available for the three video sizes.

quality while requiring less bandwidth.
"Video codec type" It can be either MJPEG or MPEG4. In MJPEG mode, the video frames are
independent. In MPEG4 mode, there are I frames and P frames. To decode a P frame need information of
the previous frame. MPEG4 consumes much less network bandwidth than MJPEG.
Five parameters are available for setting the video quality.
frame rate, which can be combined with
If the user wants to define bandwidth usage independently of the video quality,
desired bandwidth must be selected. MPEG4 video are composed by I frames and P frames as the following
sequence: IPPPPIPPPPIPPPP. "Key frame interval" determines how many related P frames will appear
after one I frame. Large "Key frame interval" can reduce the bit rate, but cause image corrupt longer if there
is packet loss while transmission. "Fix bit rate" option and "Key frame interval" option are only available in
MPEG4 mode. Video quality can be affected due to sending the maximum frame rate within the restricted
bandwidth if the pictures are fast-moving. To ensure video quality (quantising rate) independent of the
network, a greater bandwidth is used to be able to handle maximum frame rate during the transmission of
rapidly changing pictures.

Rotates the video horizontally. Select these options if the security network camera is installed
upside down or back to front.
"Improve efficiency in the multi-user environment" Check this option to improve efficiency in the multi-
user environment when running in the low bandwidth environment. But it will cause each connection slow a
few minutes when connection established.
"Time stamp on video" When selected the time stamp format is:
a) "Size" becomes Normal or Double, "Text on video" hh:mm:ss yy/mm/dd"
b) "Size" becomes half, "hh:mm:ss yyyy/mm/dd"
