Product Description

The AXIS 241Q/241S is a fully featured video server for security surveillance and remote monitoring needs. Based on the AXIS ARTPEC-2 compression chip, it can digitize up to 4 analog video sources and make these available on the network as real-time, full frame rate Motion JPEG and/or MPEG-4 video streams.

The AXIS 241Q has 4 BNC inputs for analog video devices and the AXIS 241S has 1 BNC input and a matching loop-through output. The AXIS 241S can also accommodate Y/C video using an Y/C to BNC cable (not included).

The AXIS 241Q/241S is equipped with RS-232 and RS-485 ports for the connection of third party PTZ systems. It also has 4 alarm inputs and 4 alarm outputs, which can be used to connect various third party devices, e.g. door sensors and alarm bells.

Up to 20 viewers can access the camera simultaneously when using Motion JPEG and MPEG-4 unicast. If MPEG-4 multicast is used, the number of viewers is unlimited, but when viewing with the AXIS Media Control (AMC), each viewer still needs a separate MPEG-4 decoder license. The AXIS 241Q/241S includes one such decoder license.

Additional licenses can be purchased separately from your Axis dealer. If using other clients to view the video stream, no further MPEG-4 decoder licenses are required.

Video can be viewed in 5 resolutions (up to 4CIF), and image compression is configurable. The video server contains support for video motion detection, which allows the unit to trigger on activity in the video image, and advanced scheduling tools which can also be used to trigger an event. As the AXIS 241Q/241S is designed for use in security systems, it is equipped with several security features, such as IP address filtering, several user levels with passwords, and HTTPS.

The AXIS 241Q/241S has a built-in web server, providing full access to all features through the use of a standard browser. The built-in scripting tool allows basic applications to be created, providing basic surveillance solutions. For advanced functionality, the video server can be integrated via the use of the AXIS HTTP API (see www.axis.com/developer).

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 alternative 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 there 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 each 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.

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.

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, 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.

Other MPEG-4 clients

Although it may be possible to use other clients to view the MPEG-4 stream, this is not guaranteed by Axis.

For some other clients, e.g. QuickTime™ the Video Object Type must be set to Simple. It may also be necessary to adjust the advanced MPEG-4 settings.

To assess the video stream from e.g. QuickTime™ the following path can be used:

rtsp://<ip>/mpeg4/#/media.amp

This path is for all supported methods, and the client will negotiate with the video server to determine exactly which transport protocol to use.

Notes: • <ip> = IP address.

• # = video source number or the quad stream. This is set to 1 if omitted.

Video & Image Settings

The following descriptions show examples of the available features in the AXIS 241Q/241S. For details of each setting, please refer to the online help available from each page. Click to access the online help.

Image Settings

Image Appearance

Modify the Image Appearance to optimize the video images according to your requirements.

All configuration of images and overlays will affect the performance of the video server, depending on the usage and the available bandwidth.

•High resolution generates larger files

•Lower compression improves image quality, but generates larger files

•Black & White uses less bandwidth than Color

•Rotating the image 90 or 270 degrees will lower the maximum frame rate See also the specifications for frame rates and bandwidth on page 60.

Pan Tilt Zoom

The settings here are for configuring preset positions and the PTZ Control Queue. For detailed information on these settings, please see the online help. For an overview of Pan Tilt Zoom functionality, please see page 37.

Advanced — MPEG-4 Settings

Tools for adjusting the MPEG-4 settings and for controlling the video bit rate.

The MPEG-4 standard provides many different coding tools for various applications in different situations. As most MPEG-4 clients do not support all of these tools, it is usual to instead define and use subsets for different clients or groups of clients. These settings allow you to define the type of viewing client to use.

Adjusting the maximum bit rate and setting it to variable or constant is a good way of controlling the bandwidth used by the MPEG-4 video stream.

For more information on these advanced settings, please see the online help.

Quad Stream Settings (AXIS 241Q only)

The settings are the same as the individual image settings and are active only when the quad stream view is selected, see Image Settings, on page 24.

Live View Config

Layout

These are the tools for deciding the layout of the Live View page.

The layout can be set in 3 ways:

•Use Axis look — the layout is unchanged.

•Use custom settings — modify the default page with your own colors, images etc. Click the Configure button and see the following page.

•Own Home Page — Upload and use your own custom made page as the default web page. Click the Configure button and see the following page.

The other settings on this page concern which other features to include, e.g. buttons and links. See page 29 for more information.

Customizing the default page

The appearance of the default AXIS 241Q/241S Live View page can be customized to suit your own requirements, or you can upload and use your own home page.

To upload your own files, click the

Upload/Remove button and see the description below.
