AXIS 241Q/241S - Video streams Video streams The AXIS 241Q/241S provides several video stream formats. The type you want to use depends on your requirements and the properties of your network. The Live View page in AXIS 241Q/241S provides access to Motion JPEG and MPEG-4 video streams, and to single JPEG images. Other applications and clients can also access these video streams/images directly, without going via the Live View page.
AXIS 241Q/241S - 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 (Real-Time 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.
AXIS 241Q/241S - Video streams 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 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.
AXIS 241Q/241S - Video streams Other MPEG-4 clients Although it may be possible to use other clients to view the MPEG-4 stream, it is not guaranteed that it will work in all cases. For some other clients, for example, QuickTime™ the Video Object Type must be set to Simple. It may also be necessary to adjust the advanced MPEG-4 settings. To access the video stream, for example, from QuickTime™ the following path can be used: rtsp:///mpeg4/#/media.

AXIS 241Q/241S - Technical specifications General performance considerations When setting up your system, it is important to consider how various settings and situations will affect performance. Some factors affect the amount of bandwidth (the bit rate) required, others can affect the frame rate, and some will affect both. If the load on the CPU reaches its maximum, this will also affect the frame rate.
AXIS 241Q/241S - Technical specifications Frame rates - Motion JPEG The following test results show the frame rates in frames/second (fps) for Motion JPEG streams from the AXIS 241Q/241S, using a compression level of 50%. Note that these values are guidelines only - actual values may vary.
AXIS 241Q/241S - Technical specifications Bandwidth As there are many factors affecting bandwidth, it is very difficult to predict the required amounts. The settings that affect bandwidth are: • the image resolution • the image compression • the frame rate • the MPEG-4 object type • the MPEG-4 GOV structure • the analog cameras connected to the video server There are also factors in the monitored scene that will affect the bandwidth.
AXIS 241Q/241S - Glossary Glossary Active Speaker - a speaker with a built-in power amplifier. ActiveX - ActiveX is a standard that enables software components to interact with one another in a networked environment, regardless of the language(s) used to create them. Web browsers may come into contact with ActiveX controls, ActiveX documents, and ActiveX scripts. ActiveX controls are often downloaded and installed automatically as required.
AXIS 241Q/241S - Glossary CCTV video camera - A traditional CCTV video camera is an analog camera, available in both monochrome (black and white) and color. Cameras can be set in fixed positions or placed on "Pan/Tilt/Zoom" devices, which allow the camera to be maneuvered. Using a zoom lens provides a closer view of the object being viewed. CCTV analog video cameras can be viewed over a computer network by using a video server.
AXIS 241Q/241S - Glossary Ethernet - Ethernet is the most widely installed local area network technology. An Ethernet LAN typically uses special grades of twisted pair wires. The most commonly installed Ethernet systems are 10BASE-T and 100BASE-T10, which provide transmission speeds up to 10 Mbps and 100 Mbps respectively. ETRAX (Ethernet Token Ring AXIS) - The ETRAX chip is the cornerstone of Axis technology and the 'brain' in nearly all Axis products.
AXIS 241Q/241S - Glossary Image compression - Image compression minimizes the file size (in bytes) of an image. Two of the most common compressed image formats are JPEG and GIF. See also MPEG and Motion JPEG. Interlacing - Interlaced video is video captured at 50 pictures (known as fields) per second, of which every 2 consecutive fields (at half height) are then combined into 1 frame. Interlacing was developed many years ago for the analog TV world and is still used widely today.
AXIS 241Q/241S - Glossary Motion JPEG - Motion JPEG is a simple compression/decompression technique for network video. Latency is low and image quality is guaranteed, regardless of movement or complexity of the image. Image quality is controlled by adjusting the compression level, which in turn provides control over the file size, and thereby the bit rate. High-quality individual images from the Motion JPEG stream are easily extracted. See also JPEG and GIF. Megapixel - See Pixel.
AXIS 241Q/241S - Glossary WAN (Wide Area Network) as a large single LAN (Local Area Network). This kind of interconnection is known as a virtual private network (VPN). Pre/post alarm images - The images from immediately before and after an alarm. These images are stored in a buffer for later retrieval. Progressive scan - Progressive scan, as opposed to interlaced video, scans the entire picture, line by line every sixteenth of a second.
AXIS 241Q/241S - Glossary computers. A computer running a server program is also frequently referred to as a server. In practice, the server may contain any number of server and client programs. A web server is the computer program that supplies the requested HTML pages or files to the client (web browser). SMTP (Simple Mail Transfer Protocol) - Used for sending and receiving e-mail.
AXIS 241Q/241S - Glossary Video camera - See Network camera and CCTV video camera. Video decoder - A network video decoder converts digital video streams back into analog signals, which can then be displayed on standard TV sets, analog monitors and video switches. Video encoder (video server) - A video encoder/server digitizes analog video signals and sends digital images directly over an IP network, such as a LAN, intranet or the Internet.
