AXIS 212 PTZ/-V - Video Streams
Video Streams
AXIS 212 PTZ/-V provides several different image and video stream formats. The type to use depends on your requirements and
on the properties of your network.
Unicasting is communication between a single sender and a single receiver over a network. This means that the video stream
goes independently to each user, and each user gets their own stream.
Multicast is bandwidth-conserving technology that reduces bandwidth usage by simultaneously delivering a single stream of
information to multiple network users.
The Live View page in AXIS 212 PTZ/-V provides access to Motion JPEG and MPEG-4 video streams, as well as to single JPEG
images. Other applications and clients can also access these video streams/images directly, without going via the Live View
page.
How to stream MPEG-4
Deciding on the combination of protocols and methods to use depends on your viewing requirements, and on the properties of
your network.
AXIS Media Control (AMC)
The recommended method of accessing live video (MPEG-4 and Motion
JPEG) from AXIS 212 PTZ/-V is to use AXIS Media Control (AMC) in
Microsoft Internet Explorer in Windows.
The AMC control panel can be used to configure various video and audio
settings. Please see the readme file included in the tool for more
information.
The AMC control panel is automatically installed on first use, after which
it can be configured.
Open the AMC Control Panel from:
• Windows Control Panel (from the Start menu)
• Alternatively, right-click the video image and click Settings in
the menu.
Unicast RTP This unicast method (RTP over UDP) should be
your first consideration for live unicast video,
especially when it is important to always have
an up-to-date video stream, even if some
images are dropped.
Unicasting is used for video streaming, 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 simultane-
ous unicast connections.
RTP over RTSP This unicast method (RTP tunneled over RTSP)
is useful as it is relatively simple to configure
firewalls to allow RTSP traffic.
RTP over RTSP over
HTTP
This unicast method can be used to traverse
firewalls. Firewalls are commonly configured
to allow the HTTP protocol, thus allowing RTP
to be tunneled.
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 efficient usage of bandwidth when there are large numbers of cli-
ents viewing simultaneously. A multicast broadcast cannot however, pass a network router unless
the router is configured to allow this. It is not possible to multicast over the Internet, for example.
Note also that all multicast viewers count as one unicast viewer in the maximum total of 10
simultaneous connections.
