Axis 210 Network Camera 10-pack 0197-024 Manuale Utente

The AXIS 210/211 provides several different image and video formats. The type to use 

depends on your requirements and on the properties of your network. 

The Live View page in the AXIS 210/211 provides access to Motion JPEG and MPEG-4 

video streams, as well as to single JPEG images. Other applications and clients can also 

access these video streams/images directly, without going via the Live View page. 

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

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 each and every individual image contained in the 

stream.

Note also that multiple clients accessing Motion JPEG streams can use different image 

settings.

MPEG-4
This is a video compression standard that makes good use of bandwidth, and which can 

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

The MPEG-4 standard provides scope for a large range of different coding tools for use by 

various applications in different situations, and the AXIS 210/211 provides certain subsets 

of these tools. These are represented as Video object types, which are selected for use with 

different viewing clients. The supported video object types are:

• Simple - sets the coding type to H.263, as used by e.g. QuickTime™. 
• Ad

vanced Simple - sets the coding type to MPEG-4 Part 2, as used by AMC (AXIS 

Media Control) 

When using MPEG-4 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 MPEG-4 stream. When 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. 

•MPEG-4 is licensed technology. The AXIS 210/211 includes one viewing client license. Installing 

additional unlicensed copies of the viewing client is prohibited. To purchase additional licenses, 
contact your Axis reseller.

•All clients viewing the MPEG-4 stream must use the same set of coding tools.
