    The supported video object types are: • Simple - sets the coding type to H.263 • Advanced Simple - in Axis products, this sets the coding type to MPEG-4 Part 2 AMC (AXIS Media Control) supports both object types, whilst e.g. QuickTime™ requires the Simple object type.

  • 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 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 RTP+RTSP This method (actually RTP over UDP and RTSP over TCP) should be your first consideration for live video, especially when it is important to always have an up-to-date video stream, even if some images do get dropped. This can be configured as multicast or unicast.

  • Page 27 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 28 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.
