AXIS 241Q/S/QA/SA - Using the Video Server Using the Video Server The Video Server can be used with most standard operating systems and browsers. The recommended browser is Internet Explorer with Windows, and Mozilla with other operating systems. See also the Technical Specifications, on page 56. -
Page 11: The Live View Page
•To view streaming video in Microsoft Internet Explorer, you must set your browser to allow the AXIS Media Control (AMC) to be installed on your computer. AMC is required to use audio in the AXIS 241QA/SA. AMC also provides an MPEG-4 decoder for viewing MPEG-4 video streams. This decoder is installed the first time an MPEG-4 video stream is accessed. - Page 12 Right-click on the image to save it in on your computer. The AMC viewer toolbar (AXIS Media Control) is available in Microsoft Internet Explorer only and displays the following buttons: The Play/Stop buttons start and stop the media stream.

The recommended method of accessing live video (MPEG-4 and/or Motion JPEG) and audio from the Video Server is to use the AXIS Media Control (AMC) in Microsoft Internet Explorer in Windows. This ActiveX component is automatically installed on first use, after which it can be configured by opening the AMC Control Panel applet from the Windows Control Panel. -
Page 16: Other Methods Of Accessing The Video Stream
AXIS 241Q/S/QA/SA - Video and Audio Streams Other methods of accessing the video stream Video/images from the Video Server can also be accessed in the following ways: • If supported by the client, the Video Server can use Motion JPEG server push to display video. - Page 17 Using MPEG-4 When using MPEG-4, audio is streamed using the same protocol as the video stream. When audio is transmitted using MPEG-4, the Axis product sends synchronization information along with the streams to the client that is performing the synchronization.

The audio source can be set to Microphone or Line. If you are using a microphone, the input sensitivity can be set to High or Low. See Technical Specifications, on page 55 for the exact maximum levels.
- Page 25 AXIS 241Q/S/QA/SA - Audio (AXIS 241QA/SA only) If there are problems with the sound input being too low or high, it is possible to adjust the input gain for the microphone attached to the AXIS 241QA/SA. Audio Output If the sound from the speaker is too low or high it is possible to adjust the output gain for the active speaker attached to the Video Server.
- Page 26 AXIS 241Q/S/QA/SA - Audio (AXIS 241QA/SA only) When the incoming sound is louder than the threshold, it will pass without any changes. When lower than the threshold, the incoming sound will be reduced by a certain attenuation factor. The threshold value should be set higher than the background noise, but lower than the useful audio.

Page 59: General Performance Considerations
AXIS 241Q/S/QA/SA - Technical Specifications General performance considerations When setting up your system, it is important to consider how various settings and situations will affect performance. Some factors affect the amount of bandwidth (the bit rate) required, others can affect the frame rate, and some will affect both. If the load on the CPU reaches its maximum, this will also affect the frame rate. -
