AXIS 212 PTZ/AXIS 212 PTZ-V - Video Streams
12
Video Streams
The AXIS 212 PTZ/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.
The Live View page in the AXIS 212 PTZ/AXIS 212 PTZ-V pro
vides 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.
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.
Multicasting provides the most efficient
usage of bandwidth, especially when there are large numbers of clients
viewing simultaneously. Note however, that a multicast broadcast cannot pass a network router unless the
router is configured to allow this. It is thus not possible to multicast over for example, the Internet.
Unicasting should be used for video-o
n-demand broadcasting. However, if more and more unicast clients
connect simultaneously, the server will at some point become overloaded. There is also a maximum of 20
simultaneous viewers to be considered.
RTP/RTSP
This unicast method is RTP tunneled over RTSP. This can
be used to exploit the fact that it is relatively simple to
configure firewalls to allow RTSP traffic.
RTP/RTSP/HTTP or RTP/RTSP/HTTPS
These two methods can also be used to tr
averse firewalls. Firewalls are commonly configured to allow the HTTP
protocol, thus allowing RTP to be tunneled.
MPEG-4 clients
AXIS Media Control (AMC)
The recommended method of accessing
live video (MPEG-4 and Motion
JPEG) from the AXIS 212 PTZ/AXIS 212 PTZ-V is to use the 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 in Internet
Explorer and
click Settings in the menu.
