AXIS 216FD/FD-V/MFD/MFD-V - Video Streams Video Streams The AXIS 216FD/FD-V/MFD/MFD-V provides several different image and video stream formats. The type to use depends on your requirements and on the properties of your network. The Live View page in the AXIS 216FD/FD-V/MFD/MFD-V provides access to MPEG-4 and 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.
AXIS 216FD/FD-V/MFD/MFD-V - Video Streams Important! MPEG-4 is licensed technology. The AXIS 216FD/FD-V/MFD/MFD-V includes one viewing client license. Installing additional unlicensed copies of the viewing client is prohibited. To purchase additional licenses, contact your Axis reseller.
AXIS 216FD/FD-V/MFD/MFD-V - Video Streams The Motion JPEG stream uses considerable amounts of bandwidth, but provides excellent image quality and access to each and every individual image contained in the stream. The recommended method of accessing Motion JPEG live video from the AXIS 216FD/FD-V/MFD/MFD-V is to use the AXIS Media Control (AMC) in Microsoft Internet Explorer in Windows. Note also that multiple clients accessing Motion JPEG streams can use different image settings.
AXIS 216FD/FD-V/MFD/MFD-V - Configuration Configuration This section describes how to configure the camera, and is intended for product Administrators, who have unrestricted access to all the Setup tools, and Operators, who have access to the settings for Video & Image, Audio, Live View Config and Event Configuration. The camera is configured from Setup, from a standard browser (see Minimum web browsing requirements, on page 56).
AXIS 216FD/FD-V/MFD/MFD-V - Configuration Video & Image settings Image Appearance Use these settings to change the image as required. The image can be rotated, the image resolution and compression can be adjusted, and the white balance can be changed.
AXIS 216FD/FD-V/MFD/MFD-V - Configuration 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 browser. For unlimited video stream time, select the Unlimited radio button. Note that the maximum video stream time does not apply to clients connecting via multicast. The frame rate allowed to each viewer can also be limited, to avoid bandwidth problems on the network.
AXIS 216FD/FD-V/MFD/MFD-V - Configuration Exposure priority defines the balance between image quality and the frame rate. Higher image quality may reduce frame rate and increase motion blur. A prioritized frame rate may instead increase image noise. By increasing the Max exposure time the quality of the image will increase, but the frame rate will decrease. There may also be an increase of motion blur.
AXIS 216FD/FD-V/MFD/MFD-V - Configuration As the bit rate would usually need to increase for increased image activity, but in this case cannot, the frame rate and image quality will be affected negatively. To go some of the way towards compensating for this, it is possible to prioritize either the frame rate or the image quality whenever the bit rate would normally need to be increased. Not setting a priority means the frame rate and image quality will be affected approximately equally.
AXIS 216FD/FD-V/MFD/MFD-V - Audio Audio The AXIS 216FD/FD-V/MFD/MFD-V can transmit audio to other clients using either the built-in microphone or a connected external microphone and can play audio received from other clients via a connected speaker. Note: The speaker connected to the audio output must have a built-in amplifier, e.g. PC speakers.
AXIS 216FD/FD-V/MFD/MFD-V - Audio Audio Channels Audio mode Half-duplex mode transmits and receives audio in both directions, but only in one direction at a time. This means that you must select when to receive or transmit audio with the push-to-talk button. To speak, press and hold the button (check that the microphone is not muted). When finished speaking, release the button and you will receive audio from the other end of the connection.
AXIS 216FD/FD-V/MFD/MFD-V - Audio Depending on the selected encoding, set the desired audio quality (Bit rate). The settings affect the available bandwidth and the required audio quality. The AXIS 216FD/FD-V/MFD/MFD-V can be set to trigger an event if the incoming sound level rises above, falls below or passes the set value. The Alarm level is set between 0-100%.
AXIS 216FD/FD-V/MFD/MFD-V - Live View Config 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 Axis look, with your own colors, images etc. Click the Configure button and see Customizing the default page, on page 28. • Own Home Page - Upload and use your own custom page as the default web page.
AXIS 216FD/FD-V/MFD/MFD-V - Live View Config Customizing the default page The appearance of the default 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. Upload Own Web Files Your own web files, background pictures, etc., must first be uploaded to the camera in order to be available for selection in the Custom Settings setup dialog.
AXIS 216FD/FD-V/MFD/MFD-V - Live View Config Enabling the display of the Snapshot button allows users to save a snapshot from the video stream by clicking the button. This button is mainly intended for use with browsers other than Internet Explorer, or when otherwise not using AXIS Media Control (AMC) to view the video stream. AMC (an ActiveX control) for Internet Explorer provides its own snapshot button.
AXIS 216FD/FD-V/MFD/MFD-V - Live View Config AMC Settings The administrator can disable the installation of the MPEG-4 decoder included with AMC. This is used to prevent the installation of unlicensed copies. Further decoder licenses can be purchased from your Axis dealer. HTML Examples You can add live video from the AXIS 216FD/FD-V/MFD/MFD-V to your own web site. The camera can transmit a Motion JPEG stream to up to 20 simultaneous connections, although an administrator can restrict this to fewer.
AXIS 216FD/FD-V/MFD/MFD-V - Event Configuration Event Configuration An event in the camera is when an Event Type is activated and causes certain actions to be performed. The event type is the set of parameters (or conditions) that specifies how and when which actions will be performed. A common event type is when the camera uploads images when an alarm occurs. Many event types use an Event Server, to receive uploaded images. This section describes how to set up event servers and event types, i.e.
AXIS 216FD/FD-V/MFD/MFD-V - Event Configuration Configuring Event Types An Event Type describes how and when the camera will perform certain actions. Example: If somebody passes in front of the camera and an event that uses motion detection has been configured to act on this, the camera can e.g. record and save images to an FTP server, and/or send a notification e-mail to a pre-configured e-mail address with a pre-configured message. Images can be sent as e-mail attachments.
AXIS 216FD/FD-V/MFD/MFD-V - Event Configuration Pre-trigger and Post-trigger buffers This function is very useful when checking to see what happened immediately before and/or after a trigger, e.g. 30 seconds before and/or after a door was opened. Check the Upload images checkbox under Event Types > Add Triggered... > Triggered by... to expand the web page with the available options. All uploaded images are JPEG images.
AXIS 216FD/FD-V/MFD/MFD-V - Event Configuration Motion Detection Motion detection is used to generate an alarm whenever movement occurs (or stops) in the video image. A total of 10 Include and/or Exclude windows can be configured.

General performance considerations 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.
General performance considerations Bandwidth As there are many factors that affect bandwidth, it is very difficult to predict the required amounts. The settings that affect bandwidth are: • • • • • image resolution image compression frame rate MPEG-4 GOV settings bit rate control settings There are also factors in the monitored scene that will affect the bandwidth.
