AXIS 240Q - Using the video server Notes:
To view streaming video in Microsoft Internet Explorer, you must set your web browser to allow the AXIS Media Control (AMC) to be installed on your computer. If your workstation restricts the use of additional software components, the AXIS 240Q can be configured to use a Java applet for updating JPEG images. Please see the online help for more information. When using a browser other than Microsoft Internet Explorer with AMC, instead of a stop, a snapshot and a full screen button, there is a stop and a play button in the bottom left corner of the live view page. For a description of these buttons see The Live View page, below.

The Live View page

If the AXIS 240Q has been customized, the buttons and other items described below will be displayed accordingly on the Live View page. The following provides an overview of each button: The Video Format drop-down list allows the video format on the Live View page to be temporarily changed. The Output buttons control an output directly from the Live View page. These buttons are configured under Setup > Live View Config > Layout. Pulse - click this button to activate the port for a defined period of time, e.g. to switch on a light for 20 seconds. Active/Inactive - click these buttons to manually start and stop a connected device, e.g. switch a light on/off.
These buttons start/stop the Sequence Mode. This mode is created in Setup > Live View Config > Sequence mode and automatically displays the view from 2 or more video sources at set intervals. From the Source list, select the desired video image(s). The list can contain internal video sources, external video sources, or the Quad Stream view. The Quad Stream option displays all four video images in one stream. The Action buttons trigger an event directly from the Live View page. These buttons are configured under Setup > Live View Config > Layout. Click these buttons to manually start and stop events. Use the Snapshot button to capture a snapshot of the image currently being displayed in the window. Right-click on the image to save it in on your computer.

10 AXIS 240Q - Video Streams
The AMC viewer toolbar (AXIS Media Control) is available in Microsoft Internet Explorer only and displays the following buttons: The Play/Stop buttons start and stop the live video stream. The Snapshot button takes a snapshot of the currently displayed image. The Snapshot function and the target directory for saving snapshots can be configured from AMC (AXIS Media Control), which is available from the Windows Control Panel (Internet Explorer only). Click the View Full Screen button and the video image will fill the entire screen area. No other windows will be visible. Press Esc (Escape) on your keyboard to cancel full screen view. Note that these AMC toolbar functions can also be accessed by right-clicking in the image. For information on using Pan/Tilt/Zoom controls, please see page 27.

Video Streams

The Live View page in the AXIS 240Q provides access to Motion JPEG 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.

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 provides excellent image quality and access to each and every individual image contained in the stream. The level of image compression may need to be increased if bandwidth consumption is a problem. Note also that multiple clients accessing Motion JPEG streams can use different image settings.
The AXIS Media Control (AMC)
The recommended method of accessing live video (Motion JPEG) from the AXIS 240Q 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.
AXIS 240Q - Video Streams
Other methods of accessing the video stream
Video and images from the AXIS 240Q can also be accessed in the following ways: If supported by the client, the AXIS 240Q can use Motion JPEG server push to display video. This option maintains an open HTTP connection to the browser and sends data as and when required, for as long as required. As single JPEG images in a browser. Enter e.g. the path: http://<ip>/axis-cgi/jpg/image.cgi?resolution=CIF

In the field Upload own image, click the Browse button and locate the image file on your computer or server. 3. Click the Upload button and follow the on-screen instructions. To use an already uploaded image: 1. Select an uploaded image from the Use image drop-down list. 2. Place the image at the required location by entering the x and y coordinates. 3. Click Save.
16 AXIS 240Q - Video & Image Settings
Overlay image requirements:
Image Formats Windows 24-bit BMP (full color) Windows 4-bit BMP (16 colors) Image Size The height and width of the overlay image in pixels must be exactly divisible by 4.
Overlay image limitations: The maximum overlay image size supported by the AXIS 240Q is the same as the maximum image resolution. See Technical Specifications, on page 52. When a text overlay is also used, this reduces the amount of space available to the overlay image. To keep the text readable at lower resolutions, the text overlay occupies proportionally more of the image at lower resolutions. If the overlay is initially positioned so that part of it is outside the video image, it will be relocated so that it appears over the video image, i.e. it is always the entire image that is displayed. Please see the online help for more information.

Event Servers are used for e.g. receiving uploaded image files and/or notification messages. To set up Event server for your AXIS 240Q, go to Setup > Event Configuration > Event Servers and enter the required information according to the selected server type.

PTZ Control Queue Use the PTZ Control Queue window to enable and disable PTZ queueing. This window allows you to set up a queue for viewers wanting to access the AXIS 240Q, and limits the number of viewers and the length of time each viewer can access and control PTZ. For more information on how to set up the control queue, please see the online help.
Note also that a viewer who belongs to a group (see Security - Users, on page 34) that has a higher PTZ priority can go in front of other users in the queue and take control of the AXIS 240Q.
AXIS 240Q - Pan Tilt Zoom The order of priority for taking control of the queue is listed below: 1. Administrators - An administrator may take the PTZ control regardless of who is currently first in queue. The administrator will be removed from queue 60 seconds after the their last PTZ control command. 2. Event - You can set up the AXIS 240Q to take control of the queue and move to a specific position for 20 seconds when triggered by an alarm. The event will immediately be place first in queue except when an administrator is in control. For more information see Triggered Event, on page 23. 3. Operator - Same as administrator with lower priority. 4. Guard Tour - Guard tour has control of PTZ for an indefinite period of time. It may be overridden by, Operator, Event or administrator. Guard Tour will resume when higher priority groups leaves the queue. For more information see Guard Tour, on page 31. 5. Viewer - Multiple viewers will need to wait for their turn. The viewer has 60 seconds to control PTZ until control is passed to the next viewer in queue. Note: In order to be able to identify different users in the viewer group, cookies need to be enabled on the client.

Network - Basic TCP/IP Settings
IP Address Configuration Your Axis network camera supports both IP version 4 and IP version 6. Both versions may be enabled simultaneously, and at least one version must always be enabled. When using IPv4, the IP address can be set automatically via DHCP, or a static IP address can be set manually.
38 AXIS 240Q - System Options
If IPv6 is enabled, your camera will receive an IP address according to the configuration in the network router. There are also options for setting up notification of changes in the IP address, and for using the AXIS Internet Dynamic DNS Service. For more information on setting the IP address, please see the online help. Notes:
DHCP is a protocol for automatic IP address assignment on a network. IP address assignment via DHCP may lead to the situation where the IP address changes and you lose contact. Configure the options for notification of IP address change (under Services) to receive notification from the video server when the IP address changes. Alternatively, if your DHCP server can update a DNS server, you can access the AXIS 240Q by host name which is always the same, regardless of the IP address.

Services Enable ARP/Ping setting of IP address - The IP address can be set using the ARP/Ping method, which associates the unit's MAC address with an IP address. Check this box to enable the service. Leave disabled to prevent unintentional resetting of the IP address. Notes: The ARP/Ping service is automatically disabled 2 minutes after the unit is started, or as soon as an IP address

See or ARP and Ping must be set within two minutes in Windows on page 13, or ARP and Ping in UNIX/Linux on page 14. after power has been applied to the video server The video server is located on a different subnet. If the IP address intended for the AXIS 240Q and the IP address of your computer are located on different subnets, you will not be able to set the IP address. Contact your network administrator for an IP address on the same subnet as the computer you are performing the installation from. Disconnect power from the AXIS 240Q. Run the Ping command (in a Command/DOS window, type ping <IP address of unit> If you receive: Reply from <IP address>: bytes = 32; time = 10 ms.. - this means that the IP address may already be in use by another device on your network. You must obtain a new IP address and reinstall the unit. If you receive: Request timed out - this means that the IP address is available for use with your video server. In this case, check all cabling and reinstall the unit. The AXIS 240Q cannot be accessed from a Web browser The IP address has been changed 1) Move the AXIS 240Q to an isolated network or to one with no DHCP or BOOTP server. Set the by DHCP IP address again, using the ARP Ping command. 2) Access the unit and disable BOOTP and DHCP in the TCP/IP settings. Return the unit to the main network. The unit now has a fixed IP address that will not change. 3) As an alternative to 2), if dynamic IP address via DHCP or BOOTP is required, select the required service and then configure IP address change notification from the network settings. Return the unit to the main network. The unit will now have a dynamic IP address, but will notify you if the address changes. Other networking problems Test the network cable by connecting it to another network device, then Ping that device from your workstation. See instructions above. The video server can be configured to use a SOCKS server to reach networks on the other side of a firewall/proxy server Check the Internet firewall with your system administrator.

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. The following factors are among the most important to consider: High image resolutions and/or lower compression levels result in larger images. Bandwidth affected. Access by large numbers of Motion JPEG clients. Bandwidth affected. Video channels - The number of video channels simultaneously accessed by clients affects the video servers CPU and video compression load. Simultaneous viewing of different streams (resolution, compression, etc.) by different clients. Frame rate and bandwidth affected. Heavy usage of event settings affects the CPU load. Frame rate affected. Enabled motion detection. Frame rate and bandwidth affected. HTTPS - Increases the servers CPU load when encrypting data. Heavy network utilization due to poor infrastructure. Bandwidth affected Poorly performing client PC - Lowers perceived performance.

Optimizing your system

To see the bandwidth and frame rate currently required by the video stream, the AXIS 240Q provides a tool that can be used to display these values directly in the video image. To do this, special format strings are added as part of a text overlay. Simply add #r (average frame rate in fps) and/or #b (average bandwidth in Kbps) to the overlay. For detailed instructions, please see the online help for Video & Image > Overlay Settings, and the help for File Naming & Date/Time Formats. Important!
The figures displayed here are the values as delivered by the server. If other restrictions are currently in force, (e.g. bandwidth limitation) these values might not correspond to those actually received by the client. For Motion JPEG, these values will only be accurate as long as no frame rate limit has been specified.

Aspect ratio - A ratio of width to height in images. A common aspect ratio used for television screens and computer monitors is 4:3. High-definition television (HDTV) uses an aspect ratio of 9:16. Autoiris (DC-Iris) - This special type of iris is electrically controlled by the camera, to automatically regulate the amount of light allowed to enter. AVI (Audio Video Interleave) - A video format that supports simultaneous playback of audio and video. AXIS Internet Dynamic DNS Service - This free service provides an Axis network product with a unique DNS or domain name (URL address), which can then be used instead of an IP address to access the product from a web browser. AXIS IP Utility - A tool for discovering and setting IP addresses for Axis network devices. AXIS IP Utility is supplied free of charge by Axis. AXIS Camera Management - A powerful and efficient installation and management tool for Axis network video products. The tool can automatically find and set IP addresses, show connection status and manage firmware upgrades of multiple devices. Bitmap - A bitmap is a data file representing a rectangular grid of pixels. It defines a display space and color for each pixel (or "bit") in the display space. This type of image is known as a "raster graphic." GIF's and JPEG's are examples of image file types that contain bitmaps. Because a bitmap uses this fixed raster method, it cannot easily be rescaled without losing definition. Conversely, a vector graphic image uses geometrical shapes to represent the image, and can thus be quickly rescaled. Bit rate - The bit rate (in kbit/s or Mbit/s) is often referred to as speed, but actually defines the number of bits/time unit and not distance/time unit. Bluetooth - Bluetooth is an open standard for wireless transmission of voice and data between mobile devices (PCs, handheld computers, telephones and printers). Bonjour - Also known as zero-configuration networking, Bonjour enables the automatic discovery of computers, devices, and services on IP networks. Bonjour allows devices to automatically discover each other without the need to enter IP addresses or configure DNS servers. Bonjour is developed by Apple Computer Inc. BOOTP (Bootstrap Protocol) - A protocol that can automatically configure a network device (give it an IP address). BOOTP is the basis for a more advanced network management protocol, the Dynamic Host Configuration Protocol (DHCP). Broadband - In network engineering terms, this describes transmission methods where two or more signals share the same carrier. In more popular terminology, broadband is taken to mean high-speed data transmission.

58 AXIS 240Q - Glossary

Dome network camera - A remotely controllable camera mounted in a special housing, characterized by the dome shaped glass or plastic covering behind which the camera resides. Usually mounted on a ceiling and looking downwards, a dome camera can often rotate up to 360 degrees, thus providing excellent coverage of large areas. Duplex - See Full-duplex. DVD (Digital Versatile Disc) - An optic disc with the same physical size as a CD, but with significantly greater storage capacity. DVR (Digital Video Recorder) - A DVR records analog video to a hard disk in digital format. Most DVR's use the MPEG-2 format for encoding analog video signals. Encoder - See Video encoder. 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. A multipurpose Linux chip with integrated Ethernet networking and extremely flexible I/O options. Factory default settings - These are the settings that originally applied for a device when it was first delivered from the factory. If it should become necessary to reset a device to its factory default settings, this will, for many devices, completely reset any settings that were changed by the user. Firewall - A firewall works as a barrier between networks, e.g. between a Local Area Network and the Internet. The firewall ensures that only authorized users are allowed to access the one network from the other. A firewall can be software running on a computer, or it can be a standalone hardware device. Fixed dome network camera - This type of camera cannot be remotely controlled as regards movement, but is mounted in the same type of dome as a controllable network dome camera. This camera must be positioned manually to provide the required coverage. Fixed network camera - This type of camera cannot be remotely controlled as regards movement. It must be positioned manually to provide the required coverage. Fixed iris - See Autoiris. Focal length - Measured in millimeters, the focal length of a camera lens determines the width of the horizontal field of view, which in turn is measured in degrees. FTP (File Transfer Protocol) - FTP is an application protocol that uses the TCP/IP protocols, used to exchange files between computers/devices on networks. Frame - A frame is a complete video image. In the 2:1 interlaced scanning format of the RS-170 and CCIR formats, a frame is made up of two separate fields of 262.5 or 312.5 lines interlaced at 60 or 50 Hz to form a complete frame, which appears at 30 or 25 Hz. In video cameras with a progressive scan, each frame is scanned line-by-line and not interlaced; most are also displayed at 30 and 25 Hz. Frame rate - The frame rate used to describe the frequency at which a video stream is updated is measured in frames per second (fps). A higher frame rate is advantageous when there is movement in the video stream, as it maintains image quality throughout. Full-duplex - Transmission of data in two directions simultaneously. In an audio system this would describe e.g. a telephone systems. Half-duplex also provides bi-directional communication, but only in one direction at a time, as in a walkie-talkie system. See also Simplex. G.711 - The international standard for encoding telephone audio on a 64 kbps channel. It is a pulse code modulation (PCM) scheme operating at 8 kHz sample rate. G.726 - A frequently used speech-compression algorithm in telecommunications due to its high perceived speech quality and low resource requirements. Gain - Gain is the amplification factor and the extent to which an analog amplifier boosts the strength of a signal. Amplification factors are usually expressed in terms of power. The decibel (dB) is the most common way of quantifying the gain of an amplifier. Gateway - A gateway is a point in a network that acts as an entry point to another network. In a corporate network for example, a computer server acting as a gateway often also acts as a proxy server and a firewall server. A gateway is often associated with both a router, which knows where to direct a given packet of data that arrives at the gateway, and a switch, which furnishes the actual path in and out of the gateway for a given packet. GIF (Graphics Interchange Format) - GIF is one of the most common file formats used for images in web pages. There are two versions of the format, 87a and 89a. Version 89a supports animations, i.e. a short sequence of images within a single GIF file. A GIF89a can also be specified for interlaced presentation. GOV (Group Of VOPs) - A group of VOP's is the basic unit of an MPEG-4 video stream. The GOV contains different types and numbers of VOP's (I-VOP's, P-VOP's, etc) as determined by the GOV length and GOV structure. See also VOP. GOV length - The GOV length determines the number of images (VOP's) in the GOV structure. See also GOV and VOP. GOV structure - The GOV structure describes the composition of an MPEG-4 video stream, as regards the

60 AXIS 240Q - Glossary

JPEG (Joint Photographic Experts Group) - Together with the GIF file format, JPEG is an image file type commonly used on the web. A JPEG image is a bitmap, and usually has the file suffix '.jpg' or ".jpeg." When creating a JPEG image, it is possible to configure the level of compression to use. As the lowest compression (i.e. the highest quality) results in the largest file, there is a trade-off between image quality and file size. kbit/s (kilobits per second) - A measure of the bit rate, i.e. the rate at which bits are passing a given point. See also Bit rate. LAN (Local Area Network) - A LAN is a group of computers and associated devices that typically share common resources within a limited geographical area. Linux - Linux is an open source operating system within the Unix family. Because of its robustness and availability, Linux has won popularity in the open source community and among commercial application developers. Lux - A standard unit of illumination measurement. MAC address (Media Access Control address) - A MAC address is a unique identifier associated with a piece of networking equipment, or more specifically, its interface with the network. For example, the network card in a computer has its own MAC address. Manual iris - This is the opposite of an autoiris, i.e. the camera iris must be adjusted manually to regulate the amount of light allowed to reach the image sensor. Mbit/s (Megabits per second) - A measure of the bit rate, i.e. the rate at which bits are passing a given point. Commonly used to give the "speed" of a network. A LAN might run at 10 or 100 Mbit/s. See also Bit rate. Monitor - A monitor is very similar to a television set, but lacks the electronics to pick up regular television signals. 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. MPEG (Moving Picture Experts Group) - The Moving Picture Experts Group develops standards for digital video and audio compression. It operates under the auspices of the International Organization for Standardization (ISO). The MPEG standards are an evolving series, each designed for a different purpose. MPEG-2 - The designation for a group of audio and video coding standards, and is typically used to encode audio and video for broadcast signals, including digital satellite and Cable TV. MPEG-2, with some modifications, is also the coding format used by standard commercial DVD movies. MPEG-4 - MPEG-4 is a group of audio and video coding standards and related technology. The primary uses for the MPEG-4 standard are web (streaming media) and CD distribution, conversational (videophone), and broadcast television. Most of the features included in MPEG-4 are left to individual developers to decide whether to implement them or not. This means that there are probably no complete implementations of the entire MPEG-4 set of standards. To deal with this, the standard includes the concept of "profiles" and "levels", allowing a specific set of capabilities to be defined in a manner appropriate for a subset of applications. Multicast - Bandwidth-conserving technology that reduces bandwidth usage by simultaneously delivering a single stream of information to multiple network recipients. See also Unicast. Multiplexer - A multiplexer is a high-speed switch that provides full-screen images from up to 16 analog cameras. Multiplexers can playback everything that happened on any one camera with no interference from the other cameras on the system. Network camera (Network video camera) - A network camera is a camera and computer combined in one intelligent unit. It captures and sends live video directly over an IP network such as a LAN, intranet or the Internet. Users can view and/or manage the camera using a standard web browser or application software from any local or remote computer on a network. The camera allows multiple authorized viewers from different locations to simultaneously access images. A network camera is sometimes known as an IP camera. Network connectivity - The physical (wired or wireless) and logical (protocol) connection of a computer network or an individual device to a network, such as the Internet or a LAN. Network video - Network video (often referred to as IP-Surveillance for specific applications within security surveillance and remote monitoring) is a system that gives users the ability to monitor and record video over an IP network (LAN/WAN/Internet). NTSC (National Television System Committee) - NTSC is an analog color encoding system used in television systems in Japan, the United States and other parts of the Americas. NTSC defines the video signal using 525 TV lines per frame, at a refresh rate equal to 30 frames per second. See also PAL.
