Media Streams
Media Streams
The Axis product provides several video stre am form a ts. Your requirements and the properties of your ne twork w ill determ ine the
type you use.
The Live View page in the prod uct provides access to H.264 and Motion JPEG video stream s, and to the list of available stre am profiles.
Other applications and clients can access video streams directly, without going via the Live View page.
How to S tream H.264
The video com pression standard H.264 makes good use o f bandwidth, and can provide high quality video streams at less than 1 Mbit/s.
Deciding which combination of protocols and methods to use depends on your viewing requirements, and on the properties of
your network. The available options in AXIS Media Control are:
Unicast RTP
This unicast method (RTP over UDP) is used
for live unicast video, especially w hen it is
important to always have an up-to-date video
stream, even if some images are dropped.
RTP over RTSP
This unicast method (RTP tunneled over RTSP)
is useful as it is relatively simple to configure
firewallstoallowRTSPtraffic.
RTP over RTSP over H TTP
This unicast method can be used to traverse
firewalls. Firewalls are commonly configured to
allow the H TTP protocol, thus allowing RTP to
be tunneled.
Unicasting is used for video-on-demand
transmission so that there is no video traffic
on the network until a client connects and
requests the stream.
Note that there are a maximum of 20
simultaneous unicast connections.
Multicast RTP
This method (RTP over UDP) should be used for live multicast video. The video stream is always
up-to-date, even if some images are dropped.
Multicasting provides the most effi cient usage of bandwidth when there are large numbers of
clients viewing simultaneously. A multicast cannot however, pass a network router unless the
router is configured to a llow this. It is not possible to m ulticast over the Internet, for example.
Note also that all m ultica st viewers count as one unicast viewer in the maximum total of 20
simultaneous connections.
AXIS Media Control negotiates with the Axis pr oduct to d etermine the tra nspo rt protocol to use. The order of priority, listed in the
AMC Control Panel, can be chang ed and the options disabled, to suit specific requirements.
Note
H.264 is licensed technology. The Axis product includes one H.264 viewing client license. Installing additional unlicense d
copies of the client is prohibited. To
purchase additional licenses, contact your Axis rese lle r.
MJPEG
This form at uses standard JPEG still images for the video strea m. These images are then displayedandupdatedataratesufficient
to create a stream that shows constantly updated m o tion.
The Motion JPEG stream uses considerable amounts of bandw idth, but provides excellent image qualityandaccesstoeveryimage
contained in the stream. The recommended method of accessing Motion JPEG live v id eo from the Axis product is to use the AXIS
Media Control in Intern et Explorer in Windows.
AXIS Media Control (AMC)
AXIS M ed ia Control (AMC) in Internet Exp lorer in Windows is the recommended method of accessing live video from the Axis product.
