  • Page 7: Overview - Axis 241Q/Qa

    Axis video server - Product description Overview - AXIS 241Q/QA The AXIS 241Q and AXIS 241QA each provide 4 BNC inputs for connecting analog video devices. The AXIS 241QA also provides a Line/Mic In (mono) connector for connecting an external microphone or other source producing a line level signal.
  • Page 8: Overview - Axis 242S Iv

    The AXIS 242S IV provides 1 BNC input and 1 matching loop-through output. S-Video (Y/C) is accommodated directly via the supplied connector. The AXIS 242S IV also provides Line In and Mic In connectors. These are used for audio analysis purposes only.
  • Page 9: Switches & Connectors

    (only the left channel is used from a stereo signal). Line In & Mic In (AXIS 242S IV only) - 2 separate inputs for Line In and Mic In, respectively. Note that these inputs are used for internal audio analysis only.

    The I/O terminal connector also provides an auxiliary connection point for DC power. Network connector - The Axis video server connects to the network via a standard network cable, and automatically detects the speed of the local network segment (10BaseT/100BaseTX Ethernet).
  • Page 11: Using The Video Server

    Axis video server - Using the video server Using the video server The Axis video server can be used with most standard operating systems and web browsers. The recommended browser is Internet Explorer with Windows, and Mozilla with other operating systems. See also the Technical specifications, on page 66.
  • Page 12: The Live View Page

    •To view streaming video in Microsoft Internet Explorer, you must set your web browser to allow the AXIS Media Control (AMC) to be installed on your computer. AMC is required to use audio in the AXIS 241SA and AXIS 241QA. AMC also provides an MPEG-4 decoder for viewing MPEG-4 video streams.
  • Page 13 The second icon indicates that you will hear audio from the video server, but no audio is sent to web clients. When in simplex talk mode, the icon toggles between allowing you to speak, and is dimmed when you do not want other clients to receive any audio.
  • Page 14: Video And Audio Streams

    The Live View page in the Axis video server provides access to Motion JPEG and MPEG-4 video and audio streams, as well as to single JPEG images. Other applications and clients can also access these video and audio streams/images directly, without going via the Live View page.
  • Page 15: Mpeg-4 Protocols And Communication Methods

    The recommended method of accessing live video (MPEG-4 and/or Motion JPEG) and audio from the Axis 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: How To Stream Mpeg-4

    Video/images from the Axis video server can also be accessed in the following ways: • If supported by the client, the Axis video server can use Motion JPEG server push to display video. This option maintains an open HTTP connection to the web browser and sends data as and when required, for as long as required.
  • Page 17 To access the video stream from e.g. QuickTime™ the following path can be used: rtsp://<ip>/mpeg4/#/media.amp This path is for all supported methods, and the client will negotiate with the Axis video server to determine exactly which transport protocol to use.
  • Page 18 Axis video server - Video and audio streams Accessing the audio streams In addition to accessing audio in the Live View page using AMC, audio from the AXIS 241QA/241SA can also be accessed in the following ways: AXIS VAPIX API You can read about accessing audio for the other protocols through the AXIS VAPIX HTTP API at www.axis.com/techsup...

  • Page 22: Overlay/Mask Settings

    Selecting the overlay/mask type from the menu will display further settings available for the selected type. See the online help for further information. Note: A privacy mask cannot be bypassed, but an overlay image can be bypassed with the help of the AXIS VAPIX API. Upload and use an overlay image 1.
  • Page 23 Windows 4-bit BMP (16 colors) Overlay image limitations: • The maximum overlay image size supported by the Axis video server is the same as the maximum image resolution. See the Technical Specifications, on page 66. • When a text overlay is also used, this reduces the amount of space available to the overlay image.
  • Page 24: Advanced - Mpeg-4 Settings

    Axis video server - Video & image settings Advanced - MPEG-4 settings Tools for adjusting the MPEG-4 settings and for controlling the video bit rate. The MPEG-4 standard provides many different coding tools for various applications in different situations. As most MPEG-4 clients do not support all of these tools, it is usual to instead define and use subsets for different clients or groups of clients.
  • Page 25: Audio (Axis 241Qa/Sa Only)

    Axis video server - Audio (AXIS 241QA/SA only) Audio (AXIS 241QA/SA only) The AXIS 241QA/SA can transmit audio to other clients using an external microphone and can play audio received from other clients by attaching a speaker. The Setup page for the AXIS 241QA/SA has an additional menu item called Audio, which allows different audio configurations to be set up, e.g.
  • Page 26 Audio from an external microphone or a line source can be connected to the Line/Mic In jack of the AXIS 241QA/SA. 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 66 for the exact maximum levels.
  • Page 27 Axis video server - 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 Axis video server.
  • Page 28 Axis video server - 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.
