Video Streams; How To Stream H.264 - Axis Q6032-E User Manual

Video Streams

The network camera provides several image and video stream formats. Your requirements and the properties of your network
will determine the type you use.
The Live View page in the network camera provides access to H.264 and Motion JPEG video streams, and to the list of
available stream profiles. Other applications and clients can also access these video streams/images directly, without going via
the Live View page.

How to stream H.264

This video compression standard makes good use of 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 AMC are:
Unicast RTP
RTP over RTSP
RTP over RTSP over HTTP
Multicast RTP
AMC negotiates with the camera to determine the transport protocol to use in the order listed above. This order can be
changed and the options disabled, to suit specific requirements.
Important!
H.264 is licensed technology. The network camera includes one viewing client license. Installing additional unlicensed
copies of the viewing client is prohibited. To purchase additional licenses, contact your Axis reseller.
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.
This unicast method (RTP tunneled over RTSP) is
useful as it is relatively simple to configure fire-
walls to allow RTSP traffic.
This unicast method can be used to traverse fire-
walls. Firewalls are commonly configured to allow
the HTTP protocol, thus allowing RTP to be tun-
neled.
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 clients 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.
AXIS Q6032-E - Video Streams
Unicasting is used for video-on-demand broadcasting,
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 10 simultaneous
unicast connections.
