7.4.2 Stream Setup
Click on Stream Setup under the Camera Menu to change the streaming settings for your camera. This is
useful if you require a certain size of video stream, a certain quality, or different streams for different
devices (such as laptop or mobile phone). Default settings will normally suffice for most users.
[Preset]
There are five pre-programmed stream profiles for quick set-up. Please choose the one according
to your bandwidth.
[Image size]
Image resolutions available are as follows:
480P Model
: 640 x 480(VGA), 320 x 240(QVGA), 160 x 120 (QQVGA). The mobile stream has a fixed image
size of 176x144.
HD 720 Model
: 1280x720 (HD720p), 768x432, 512x288, 256x144). The mobile stream has a fixed image
size of 176x144.
HD 1080 Model
: 1920x1080 (HD1080p), 1280x720 (HD720p), 768x432, 512x288, 256x144. The mobile
stream has a fixed image size of 176x144.
[Frame rate]
Twelve options: 1/2/3/4/5/6/8/10/15/20/25/30 frames per second (fps). The frame rate is
automatically determined by the camera and this depends on the network bandwidth available at the
time. This frame rate setting imposes the maximum frame rate that the camera will transmit.
[H.264/MPEG4 bit rate]
Select H.264/MPEG4 bit rate.
These settings determine the image quality,
however higher bitrates require greater bandwidth. Please select the appropriate settings according to
your connection speed and network traffic. If you are experiencing jerky video it may be necessary to
decrease the bitrate.
[MJPEG Quality]
This sets the quality of the video when viewing the camera using Motion JPEG (without
audio). It can be from 20 to 100 where 100 is the best quality.
[JPEG snapshot Quality]
The quality of the snapshot saved using Live View page (Internet Explorer only). It
also affects the quality of the snapshot to be uploaded to an FTP Server. It can be from 20 to 100 where
100 is the best quality.
[Audio]
Select or disable the audio bit rate.
