4.  Installation  

The following descriptions show examples of some of the features available with GANZ PixelPro.   

4.1  Installation Mode  

Installation Mode allows use of the analog BNC output from the camera to connect the camera 

to a service monitor, in order to adjust the positioning of the camera and focus the lens.   

ON :    Analog Output is enabled; both IP video streams are set to VGA (640 x 480) resolution.   

OFF :    Analog Output will be disabled. 

NOTE:  You must turn Installation Mode OFF to utilize the Megapixel features of the camera. 

5.  Camera and Image  

The following descriptions show examples of some of the features available with GANZ PixelPro.   

5.1  Video Codec  

This section allows you to choose the compression codec for each of the video streams. 

Motion JPEG   

This format uses standard JPEG still images in the video stream. These images then are displayed 

and updated at a rate sufficient to create a stream that shows constantly updated motion.   

The Motion JPEG stream uses considerable amounts of bandwidth, but also provides excellent 

image quality and access to every individual image contained in the stream.   

Multiple clients accessing Motion JPEG streams could use different image settings. 

H.264 

This is a video compression standard that makes good use of bandwidth and could provide 

high-quality video streams at less than 1 Mbit/s.   

The H.264 standard provides the scope for a large range of different coding tools for use by 

various applications in different situations, and the GANZ PixelPro provides certain subsets of 

these tools.   

Using H.264, it is also possible to control the bit rate, which in turn allows the amount of bandwidth 

usage to be controlled. CBR (Constant Bit Rate) is used to achieve a specific bit rate by varying the 

quality of the H.264 stream. While using VBR (Variable Bit Rate), the quality of the video stream is 

kept as constant as possible, at the cost of a varying bit rate.
