AXIS 225FD - Video Streams

Video Streams

The AXIS 225FD provides several different image and video formats. The type to use depends on your requirements and on the properties of your network.

The Live View page in the AXIS 225FD 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.

Video Stream Types

Motion JPEG

This format uses standard JPEG still images in the video stream. These images are then displayed and updated at a rate sufficient to create a stream that shows constantly updated motion.

The Motion JPEG stream uses considerable amounts of bandwidth, but also provides excellent image quality and access to each and every individual image contained in the stream.

Note also that multiple clients accessing Motion JPEG streams can use different image settings.

MPEG-4

This is a video compression standard that makes good use of bandwidth, and which can provide high-quality video streams at less than 1 Mbit/s.

The MPEG-4 standard provides scope for a large range of different coding tools for use by various applications in different situations, and the AXIS 225FD provides certain subsets of these tools. These are represented as Video object types, which are selected for use with different viewing clients. The supported video object types are:

• Simple - sets the coding type to H.263, as used by e.g. QuickTime™.

• Advanced Simple - sets the coding type to MPEG-4 Part 2, as used by AMC (AXIS Media Control)

When using MPEG-4 it is also possible to control the bit rate, which in turn allows the amount of bandwidth usage to be controlled. CBR (constant bit rate) is used to achieve a specific bit rate by varying the quality of the MPEG-4 stream. When using VBR (variable bit rate), the quality of the video stream is kept as constant as possible, at the cost of a varying bit rate.

Notes: •MPEG-4 is licensed technology. The AXIS 225FD includes one viewing client license. Installing

additional unlicensed copies of the viewing client is prohibited. To purchase additional licenses, contact your Axis reseller.

•All clients viewing the MPEG-4 stream must use the same set of coding tools.

AXIS 225FD - Video Streams

MPEG-4 protocols and communication methods

To deliver live streaming video over IP networks, various combinations of transport protocols and broadcast methods are employed.

• RTP (Realtime Transport Protocol) is a protocol that allows programs to manage the real-time transmission of multimedia data, via unicast or multicast.

• RTSP (Real Time Streaming Protocol) serves as a control protocol, to negotiate which transport protocol to use for the stream. RTSP is thus used by a viewing client to start a unicast session, see below.

• UDP (User Datagram Protocol) is a communications protocol that offers limited service for exchanging data in a network that uses the Internet Protocol (IP). UDP is an alterna tive to the Transmission Control Protocol (TCP). The advantage of UDP is that it is not required to deliver all data and may drop network packets when ther e is e.g. network congestion. This is suitable for live video, as there is no point in re-transmitting old information that will not be displayed anyway.

• 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 e ach user gets their own stream. A benefit of unicasting is that if one stream fails, it only affects one user.

• Multicast is bandwidth-conserving technology that reduces bandwidth usage by simultaneously delivering a single stream of information to multiple network recipients. This technology is used primarily on delimited networks (intranets), as each user needs an uninterrupted data flow and should not rely on network routers.

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. Setting the preferred method(s) is done in the control applet for AMC, which is found in the Windows Control Panel. When this has been set, AMC will test all the selected methods in the specified order, until the first functioning one is found.

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 e.g. the Internet.

AXIS 225FD - Video Streams

Unicasting should be used for video-on-demand broadcasting, so that there is no video traffic on the network until a client connects and requests the stream. However, as more and more unicast clients connect, the traffic on the network will increase and may cause congestion. Although there is a maximum of 20 unicast viewers, note that all multicast users combined count as 1 unicast viewer.

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 traverse firewalls. Firewalls are commonly configured to allow the HTTP protocol, thus allowing RTP to be tunneled.

The AXIS Media Control

The recommended method of accessing live video (MPEG-4 and/or Motion JPEG) from the AXIS 225FD is to use the AXIS Media Control (AMC) in Microsoft Internet Explorer in Windows. This ActiveX component is automatically installed on first use, after which it can be configured by opening the AMC Control Panel applet from the Windows Control Panel. Alternatively, right-click the video image in Internet Explorer.

Setup Tools

The AXIS 225FD is configured from the setup tools, which are available from the link in the web interface. The setup tools can be used by:

• administrators, who have unrestricted access to all the Setup tools

• operators, who have access to the Video & Image, Live View Config and Event Configuration settings.

Accessing the setup tools from a browser

Follow the instructions below to access the Setup Tools from a browser.

1. Start your browser and enter the IP address or host name of the camera in the location/address field.

2. The Live View page is now displayed. Click Setup to display the Setup tools.

AXIS 225FD - Video and Image Settings

Video and Image Settings

The following descriptions show examples of some of the features available in the AXIS 225FD. For details of each setting, please refer to the online help available from the setup tools. Click

to access the online help.

Image Settings

Image Appearance

Adjust these settings to optimize the video images according to your requirements. All configuration of images and overlays will affect the camera’s overall performance,

depending on how it is used and on the available bandwidth. Lower compression improves video image quality, but increases the bandwidth.

The video image can be rotated and fine-tuned by adjusting the color level, the brightness, sharpness and the contrast. Please see the online help for further information on these settings.

Changed video image settings have immediate effect on the MPEG-4 stream, but the Motion JPEG stream will have to be started (or restarted) before the settings take effect.

Video Stream

Define the maximum video stream time per session in seconds, minutes or hours. When the set time has expired, a new stream can be started by refreshing the page in the Web browser. For unlimited video stream time, set this value to 0. This setting is only applicable to Motion JPEG.

The frame rate allowed to each viewer can also be limited, to avoid bandwidth problems on the network.

Test

To preview the image before saving, click Test. Note that the preview image will be in JPEG format, even though the settings are valid both for Motion JPEG and MPEG-4.

Overlay/Mask Settings

Text Overlay

These settings enable you to place text at the top or bottom of an image, e.g. date, time or some other text.

Overlay/Mask Type

Text, date and time overlays

Overlay image

When using an image overlay, select from the following options the type to use:

• Uploaded image as overlay - usually used to provide extra information in the video image.

• Uploaded image as privacy mask - conceals part of the video image.

• Configurable areas as privacy masks - up to 3 black areas are used to conceal parts of the video image.

The difference between an overlay and a privacy mask is that a privacy mask cannot be bypassed by accessing the video stream with the help of the AXIS HTTP API, whereas an overlay can.

Selecting the overlay/mask type will display further settings available for the selected type. See the online help for further information.
