  • Page 10: 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 67.

  • Page 11: 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, AXIS 241QA and AXIS 243SA. AMC also provides an MPEG-4 decoder for view- ing MPEG-4 video streams.
  • 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.

  • Page 13: 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 14: 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 15: 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 16 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 17 Axis video server - Video and audio streams QuickTime/Windows Media Player It is possible to use QuickTime and Windows Media Player to listen to the audio stream using the same methods to access video streams. Java Applet The Java applet supports simplex audio.

    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 22 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 67. • When a text overlay is also used, this reduces the amount of space available to the overlay image.

  • Page 23: 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 24: Audio (Axis 241Qa/Sa & Axis 243Sa Only)

    Note: The speaker attached to the audio output of the AXIS 241QA/SA and AXIS 243SA must have a built-in amplifier, which is the case for e.g. some PC speakers.
  • Page 25 Simplex - AXIS 241QA/SA and AXIS 243SA microphone only mode only transmits audio from the AXIS 241QA/SA and AXIS 243SA to any web clients. It will not receive audio from any other web clients. This can be used in remote monitoring, web attractions etc., to provide live audio, as well as video, of a monitored situation.
  • Page 26 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 and AXIS 243SA. Select the desired audio Encoding format, G711, G726.
  • Page 27 Axis video server - Audio (AXIS 241QA/SA & AXIS 243SA only) Noise cancelling is a way of reducing the background noise when there is no useful audio present. A typical application could be when there is a noisy environment and you are only interested in hearing the sound when someone is speaking close to a microphone.

    HTTPS For greater security, the Axis video server can be configured to use HTTPS (Hypertext Transfer Protocol over SSL (Secure Socket Layer)). That is, all communication that would otherwise go via HTTP will instead go via an encrypted HTTPS connection.
  • Page 47 The one used in the Axis implementation is EAP-TLS (EAP-Transport Layer Security). The AXIS network video device presents its certificate to the network switch, which in turn forwards this to the RADIUS server. The RADIUS server validates or rejects the certificate and responds to the switch, and sends its own certificate to the client for validation.
  • Page 48 A: OK 1. A CA server provides the required signed certificates. 2. The Axis video device requests access to the protected network at the network switch. The switch forwards the video device’s CA certificate to the RADIUS server, which then replies to the switch.
