Using the Video Setting screen, review the default video settings. The choice of settings in this menu has a
direct impact on the video quality.
Streaming Method
is used to select how video is delivered to its destination; choose TCP Only for
Unicast or Multicast Only for Multicast. (Note: These are the only options supported by ViconNet.)
Audio In
must be set to Disabled (ViconNet does not currently support audio from these models).
Resolution
field is used to set the resolution of the images sent by the cameras. Choose from
1280x1024, 1280x720, 640x480, 320x240 or 160x120 in the drop down list.
Frame Rate Mode
(fps), how many frames can be compressed and transmitted per second, is set
to Constant or Variable. If you wish to receive different FPS on different PCs, set this value to
variable.
Encoder Type
selects the type of compression, MPEG-4 or M-JPEG. This choice changes the
menu; for M-JPEG mode, a
Video Quality
field (1-100) displays instead of Video Bitrate/Video
Maximum Bitrate/Bitrate for MPEG-4. (Note: For use with ViconNet VMC, set to M-JPEG.)
Video Bitrate Mode
options (MPEG-4 only) are Constant Bit Rate or Variable Bit Rate. If the Video
Bitrate is set to variable, the Video Quality can only be set to Low, Middle or High; if it is set to
constant, the
Video Maximum Bitrate
is selectable from 28 K - Unlimited. It is suggested that the
Constant Bit Rate be selected, since it provides more exact control over the network.
Select the
Bitrate
(MPEG-4/Unlimited Video Maximum Bitrate only), 28K – 3M. Refer to Tables 1
and 2 that follow for guidelines in setting bitrate mode.
