AXIS 233D - Video Streams

Video Streams

The AXIS 233D 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 233D 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.

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 more 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.

Notes: • MPEG-4 is licensed technology. The AXIS 233D includes one viewing client license. Installing addi-

tional 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 image settings.

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 233D 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.

AXIS 233D - 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 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. 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.

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.

AXIS 233D - Video Streams

The AXIS Media Control

The recommended method of accessing live video (MPEG-4 and/or Motion JPEG) from the AXIS 233D 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.

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, under Video & Image > Advanced > MPEG-4. 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 network camera to determine exactly which transport protocol to use.

Notes: <ip> = IP address

Example:

To set up PTZ coordinates in text overlay.

To show the Preset and OSDI Zone name as text overlay use #P #L

Video Stream

The Maximum video stream time can be set as Unlimited, or a maximum stream time per session in seconds, minutes or hours can be defined. When the set time has expired, a new stream can be started by refreshing the page in the Web browser. Note that the maximum video stream time does not apply to clients connecting via multicast.

To avoid bandwidth problems on the network, the frame rate allowed to each viewer can also be limited. Select either Unlimited or define a maximum frame rate per viewer.

For a preview of the image and overlay settings before saving, click Test. When you are satisfied with the settings, click Save.

Overlay image requirements Overlay image limitations Image Formats Image Size

• Windows 24-bit BMP (full color)

• Windows 4-bit BMP (16 colors)

• OS/2 4-bit BMP (16 colors)

The height and width of the overlay image in pixels must be exactly divisible by 4.

• If the image overlay and text overlay are larger than the video image, no overlay will be displayed. When also using a text overlay, this will occupy 16 pixels in height and as many in width as the video image.

• 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. the entire image is always displayed.

• The maximum overlay image size supported by the AXIS 233D is the same as the maximum image resolution. See Technical Specifications, on page 46.

Privacy Mask

Privacy masks allow you to mask areas in an image that are prohibited for the viewer. A 3D mask, covers the area regardless of the camera’s angle or zoom position.

To set up a privacy mask:

1. Go to Setup > Video & Image > Privacy Mask and click on the Add button.

2. Move the camera’s view so that the area to be masked is at the center of the image.

3. Use zoom or change the Width and Height values to adjust size of the masked area.

4. Click Save.

Advanced Camera Settings

To optimize the lighting settings according to your requirements, modify the following settings under Lighting Conditions:

• Color level, Brightness and Sharpness- Find the level that best suits your image needs by testing.

• Exposure control - this setting is used to adapt to the amount/type of light being used. Allow slow shutter can be enabled/disabled when the exposure control is set to Automatic.

• Exposure area-This setting determines which part of the image will be used to calculate the exposure.

• IR cut filter - when the IR cut filter is set to OFF, the camera will be able to ‘see’ infrared light, e.g. at night, thus making the image clearer. The image is shown in black & white when the IR cut filter is off. Note: If set to Auto, the camera will automatically switch between IR cut filter ON and OFF, according to the current lighting conditions. This is only possible when the iris is set to Auto Iris, and the exposure control is set to Automatic.

• Wide dynamic range - Corrects the exposure when the contrast is extreme

AXIS 233D - Video & Image Settings

between light and dark in an image. Test the different levels to find the one that works best of your light conditions.

• Backlight compensation - this setting is used to make the subject appear clearer, e.g. against a bright background.

Low Light Behavior

The settings for Low Light Behavior determine how the camera will behave at low light levels. These settings affect video image quality and frame rate.

Exposure control - This setting is used to adapt to the amount or type of light used. Automatic is the default setting and can be used in most situations. The shutter speed is automatically set to produce optimum image quality. Use Manual if you have special requirements for the exposure setting

Max exposure time - Increasing the exposure time will improve image quality, but at the expense of the total frame rate. There may also be an increase in motion blur.

Max gain - Measured in decibels (dB), the default value is 36 dB. A high level of amplification may provide a better image in very low light situations.

Shutter speed - A slower shutter speed in dark conditions will help to produce a brighter image, but will produce fewer frames per second which may cause images to be blurry during motion.

Please use the online help files for more information.

Image Settings

• Auto focus enabled (default setting).

• Stabilizer - When monitoring an environment that is subject to vibrations (i.e. traffic control) the images can appear to be unsteady. Choose the frequency (High or Low) that best applies to your environment to improve image quality.

• Image freeze on PTZ - Set this option to On to freeze the image during camera movement. Once the camera reaches its position the current image is shown. Auto freezes images only between preset positions.
