AXIS Q1604–E Network Camera
Media streams
Media streams
The Axis product provides several audio and video stream formats. Your requirements and the properties of your network will
determine the type you use.
The Live View page in the product provides access to H.264 and Motion JPEG video streams, audio streams and to the list of available
stream profiles. Other applications and clients can access video and audio streams directly, without going via the Live View page.
How to stream H.264
The video compression standard H.264 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 AXIS Media Control are:
Unicast RTP This unicast method (RTP over UDP) is used
for live unicast video, especially when 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 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.
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 efficient 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 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 20
simultaneous connections.
AXIS Media Control negotiates with the Axis product to determine the transport protocol to use. The order of priority, listed in the
AMC Control Panel, can be changed 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 unlicensed
copies of the client is prohibited. To purchase additional licenses, contact your Axis reseller.
MJPEG
This format uses standard JPEG still images for the video stream. These images are then displayedandupdatedataratesufficient
to create a stream that shows constantly updated motion.
The Motion JPEG stream uses considerable amounts of bandwidth, but provides excellent image qualityandaccesstoeveryimage
contained in the stream. The recommended method of accessing Motion JPEG live video from the Axis product is to use the AXIS
Media Control in Internet Explorer in Windows.
AXIS Media Control (AMC)
AXIS Media Control (AMC) in Internet Explorer in Windows is the recommended method of accessing live video from the Axis product.

AXIS Q1604–E Network Camera
Video and Audio
Setting the compression level affects the image quality and bandwidth; the lower the compression, the higher the image quality
with higher bandwidth requirements.
To avoid bandwidth problems on the network, you can limit the frame rate allowed to each viewer. The maximum frame rate can be
set to Unlimited, or you can limit the frame rate to a value.
An image or text can be superimposed over the image as overlay. See
Overlay, on page 23 .
Save your settings before they can take effect.
H.264
H.264, also known as MPEG-4 Part 10/AVC, is a video compression standard that provides high quality video streams at low bit rates.
An H.264 video stream consists of different types of frames such as I-frames, P-frames and B-frames. An I-frame is a complete image
whereas P-frames and B-frames only contain the differences from previous/future frames.
The GOV length is the number of frames between two consecutive I-frames. Increasing the GOV length may save considerably on
bandwidth requirements in some cases, but may also have an adverse affect on image quality.
The Axis product supports two H.264 profiles.TheMainprofile provides higher compression than the Baseline profile with the same
video quality, but requires more processing power to decode.
ThebitratecanbesetasVariable Bit Rate (VBR) or Constant Bit Rate (CBR). VBR adjusts the bit rate according to the image
complexity, using up more bandwidth for increased activity in the image, and less for lower image activity. CBR allows you to set a
fixed Target bit rate that consumes a predictable amount of bandwidth. As the bit rate would usually need to increase for increased
image activity, but in this case cannot, frame rate and image quality are affected negatively. To partly compensate for this, it is
possible to prioritize either frame rate or image quality. Not setting a priority means that frame rate and image quality are equally
affected. You must save your settings before they can take effect.
The current bit rate can be set to appear as text overlay. To do this, select the Include text check box option under Overlay
Settings and enter the modifier#b in the field.
MJPEG
Sometimes the image size is large due to low light or complex scenery. Adjusting the maximum frame size helps to control the
bandwidth and storage used by the Motion JPEG video stream in these situations. Setting the frame size to the Default setting
provides consistently good image quality at the expense of increased bandwidth and storage usage in low light. Limiting the frame
