Video
"Video title" The text appears in the black bar above the video window with a timestamp. This
timestamp (date and time) is supplied by the CMOS network camera, and the date and time are
supplied by an integrated realtime clock.
"Color" Selects between colour and monochrome display.
"Power line frequency" Fluorescent light pulses with the mains frequency. Adapt the mains
frequency to eliminate this pulsing in the picture.
„Mode (Compression)" JPEG or MPEG-4 compression is possible
"Frame size" Four options are available for the three video sizes: "176x144", "320x240" and
"640x480".
Three parameters are available for setting the video quality.
"Max frame rate" Restricts the maximum frame rate, which can be combined with the "Key frame
interval" (only in MPEG-4 mode) to optimise bandwidth use and video quality. If the user wants to
define bandwidth usage independently of the video quality, "Constant bit rate" and the desired
bandwidth must be selected. 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.
"Flip" Rotates the video vertically.
"Mirror" Rotates the video horizontally. Select these options if the CMOS network camera is installed
upside down or back to front.
