AXIS Q7424–R
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 streamsandtothelistofavailable
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 Q7424–R
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 18 .
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 and P-frames. An I-frame is a complete image whereas
P-frames only contain the differences from previous 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.
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 qualityareaffectednegatively.Topartly 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
size optimizes bandwidth and storage usage, but may give poor image quality. To prevent increased bandwidth and storage usage,
the maximum frame size should be set to an optimal value.
Quad stream
A Quad view displays images from all four channels on a single screen; where the images from each camera take up a quarter of
the display area. It is possible to define settings for the video stream in quad view.
Stream Profiles
There are four pre-programmed stream profiles available for quick set up. The settings for these can be adjusted. New customized
profiles can also be created. Each profile has a descriptive name, indicating its purpose.
•Thestreamprofiles can be accessed from the Stream profile drop-down list in the Live View page.
• To add, copy, modify, and remove stream profiles go to Video & Audio >Stream Profiles.
• To select the default stream profile go to Live View Config>Stream Profile and choose the profile from the drop-down list.

• The values in the Offset Adjustments fields affect the horizontal and vertical synchronization for the image. This can be used
to eliminate any black border surrounding the image. High values, both negative and positive can put the image out of sync.
• De-interlacing - is used to improve video stream image quality from analog devices. Select any of the following options
from the De-interlacing drop-down list. Select None if de-interlacing is not necessary; Blending for improved image quality
that is not as processor intensive; Adaptive Interpolation performs de-interlacing of the video stream by applying different
filters on the image. This may give a better result than Motion Adaptive Interpolation in rare cases; Motion Adaptive
Interpolation performs de-interlacing of the video stream by applying different filters depending on the motion in different
parts of the image. This will in most cases result in the best image quality.
•Antialiasing will minimize distortion known as aliasing, which happens when a high-resolution image is represented at
alowerresolution.
• For each video input 75 Ohm video termination can be enabled/disabled via the product's web page at Video & Audio >
Video Input > Video termination. These terminations are enabled on factory default. In cases where the product is to be
connected in parallel with other equipment, for optimum video quality, it is recommended that termination be enabled for
only the last device in the video signal chain.
Image Settings
Noise reduction - Set to On to enable noise reduction. Noise reduction may increase the amount of motion blur.
Privacy Mask
A privacy mask is an area of solid color that prohibits users from viewing parts of the monitored area. Privacy masks cannot be
bypassed via the VAPIX® Application Programming Interface (API).
The Privacy Mask List (Video & Audio >Privacy Mask) shows all the masks that are currently configured in the Axis product and
indicates if they are enabled.
You can add a new mask, re-size the mask with the mouse, choose a color for the mask, and give the mask a name.
For more information, see the online help
Note
Privacy mask is not available for the quad stream. However, privacy masks configured on each channel will be displayed
in the quad.
Overlay
Overlays are used to provide extra information, for example for forensic video analysis or during product installation and
configuration. Overlays are superimposed over the video stream.
An overlay text can display the current date and time, or a text string. When using a text string, modifiers can be used to display
information such as the current bit rate or the current frame rate. For information about available modifiers, see
File Naming &
Date/Time Formats
in the online help .

Audio Settings
The audio functionality for each video stream is enabled under Video & Audio >Video Stream >Audio.
Select the desired audio channel from the drop-down list.
Audio Channels
Select the type of audio transmission from the Audio mode: drop-down list (Video & Audio>Audio Settings). The different types are:
Full duplex - Simultaneous two-way audio allowing you to transmit and receive audio (talk and listen) at the same time. There is no
echo cancellation; if feedback loops appear, try moving the microphone or the speaker.

AXIS Q7424–R
Video and Audio
Half-duplex - Audio can be transmitted in both directions between the Axis product and the client computer, but only in one
direction at a time. You must actively receive sound using the Talk/Listen button visible in the Live View page (see
AXIS Media
Control viewer toolbar
). In Push-To-Talk mode, click and hold the button to speak and release it when done. In Toggle mode, click
once to switch between speaking and listening. The Talk/Listen mode is configured from the Audio tab in the AMC control panel
(see AXIS Media Control on
page 12 ).
Simplex - Network Camera speaker only - Audio is transmitted from the client to the Axis product and played by the speaker
connected to the product. To send audio, the Talk and Microphone buttons in the AMC toolbar must both be enabled. Click either
button to stop audio transmission.
Simplex - Network Camera microphone only - Audio captured by the microphone connected to the Axis product is transmitted from
theproducttooneormoreclients.

Audio Input
Source - Select Microphone for an external microphone or Line for a Line in device, e.g. an audio mixer for multiple microphones or
a microphone with a built-in amplifier.
Microphone power - The Enable microphone power option provides DC power for an external microphone. Microphone power
should only be used with microphones that have no battery. This setting should not be enabled when using a dynamic or battery
powered microphone. Microphone power will not harm the microphone; if you are uncertain, try switching it off and on. To use a
professional microphone requiring 48V phantom power, you need an external power supply and a balanced-unbalanced converter
(audio transformer) in between.
Input gain - Control the volume (dB Full Scale) of the audio input. If the sound is too low, choose a higher dB, to amplify the
sound. If the sound is too high, choose a lower dB. The Level bar gives a visual representation of the audio signal level in dB
relative to the full-scale input level.
• Green — the signal is at a good level.
• Yellow — the signal is becoming distorted.
• Red — the signal is distorted.
Encoding - Select digital audio encoding format.
•AAC requires a license for both encoding and decoding. AAC is the least complicated and most widely used codec.
If achieving the best possible audio quality is a priority, AAC is the recommended codec to use. An AAC license
is included in the Axis product.

•G726
Sample rate - The number of times per second the sound is sampled. A higher sample rate will provide better audio quality, but
also requires a greater bandwidth.
Bit rate - Set the required bit rate depending on the selected encoding. A higher bit rate will give better audio quality. A lower bit
rate may have latency or delay, but will require less bandwidth.
