Axis Communications 230 MPEG-2 - Manual (Page 7)

AXIS 230 Introduction 7
Superior Imaging - The MPEG-2 video stream can be viewed on a LAN by up to 3 standard
(unicast) clients, or by unlimited numbers of multicast clients. Full frame rate (25/30
frames per second) is assured, provided the required bandwidth is available. Four different
image resolutions up to 720x576 (PAL) / 520x480 (NTSC) are available, and the video
quality is configurable to 7 different levels. Each client (unicast or multicast) viewing the
media stream requires its own license. Further licenses may be purchased from your
reseller.
Audio functionality - The AXIS 230 supports uni-directional audio, from the camera to the
viewer and is supplied with an integrated mono microphone. Also provided is an audio
input, for connecting an external microphone or other source producing an amplified
signal. The Audio Level alarm will alert remote operators in the event that sound is
detected above a user-defined level.
Event functionality - Events can be triggered via either of the two alarm inputs, or via the
Audio Level Alarm. The actions preformed by events are configured via the settings in the
web interface, and can include the remote storage of MPEG-2 video recordings to FTP
servers, and/or the activation of external devices through the available relay output. It is
also possible to enable a pre-alarm video buffer, allowing up to 1 minute of video to be
buffered in the server and transmitted when the event occurs. Users can also be notified of
events by email.
Security - Multi-user and multi-level password protection. Administrators can create and
modify accounts for authorized users, as well as allow anonymous viewing. The built-in
firewall provides IP address filtering, thus preventing unauthorized access.
