AXIS 231D+/232D+ - Video Streams

Video Streams

The AXIS 231D+/232D+ 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 231D+/232D+ 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 considerable amounts of 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 231D+/232D+ includes one viewing client license. Installing

additional 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 231D+/232D+ 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.

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 ther e 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 e ach 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 231D+/232D+ - Video Streams

The AXIS Media Control

The recommended method of accessing live video (MPEG-4 and/or Motion JPEG) from the AXIS 231D+/232D+ 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. 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>/mpeg4/1/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

to access the help files.

Image Settings

To optimize the video images according to your requirements, modify the following settings under Image Appearance. Each setting is described in the online help files

All configuration of images and overlays will affect the performance of the network camera, 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 in General performance

image. Image overlays can be placed anywhere in the video image.

To upload an overlay image, see below.

Example: If there is information in a monitored

area that you do not wish to disclose, you can mask it out by placing an overlay image on top. Setting the overlay image anywhere in the video image using coordinates allows precision detail masking.

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.

Please use the online help files for more information.

Overlay Image Settings

An overlay image is an image included in the video image. This might, for example, be your own company logo. Follow these instructions to upload and use an overlay image:

1. Go to Setup > Video & Image > Overlay Image.

2. To upload the file (a logo or image) to the AXIS 231D+/232D+, click the Browse button and locate it on your computer or server.

3. Click the Upload button and follow the on-screen instructions.

4. The image is now available in the Use overlay image drop-down list.

5. Click Save.

6. Go to Setup > Video & Image and modify the parameters under Overlay Settings.

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 231D+/232D+ is the same as the maximum image resolution. See Technical Specifications, on page 46.

Advanced Camera Settings

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

• White balance - the white balancing system in the AXIS 231D+/232D+ can automatically detect white in the image and intelligently use this as a reference for other colors.

• 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.

• IR cut filter (AXIS 232D+ only)- 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.

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

Image Settings

• Auto focus enabled (default setting).

• Sensitivity - sets the speed of the auto focus. High is used when focusing on objects that move frequently. Low improves the stability of the focus.

In certain situations, the white balancing system will not operate effectively. Problems may occur if the

Note:

image contains no white color at all, or if the dominant color is not white. In these circumstances, the white balance may incorrectly be based on another visible color in the image, and colors may become distorted. A pale background picture with reddish or blue foreground objects is very symptomatic of this condition. In such cases it is recommended that a fixed white balance setting is selected.

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 files

Pan Tilt Zoom Controls

The controls available for Pan Tilt Zoom (PTZ) are displayed on the Live View page by default. The administrator can enable/disable the controls for specified users.

Source / Preset positions

Tilt bar

PTZ controls

• the Pan bar - moves the camera to the right and left

• the Tilt bar - tips the camera up and down

• the Zoom bar - zooms the view in and out

• the Focus bar - adjusts the focus

• the Iris bar - adjusts the brightness of the image

Clicking on the bars themselves or on the arrows at the end of the bars will move the camera to a new position.

Each position on the bar (see right) represents a defined position in the camera’s range of movement, with the center of the bar representing the point midway between the two extremes of movement.

Page 26

AXIS 231D+/232D+ - Live View Config

Clicking a position directly on the bar moves the camera directly to the new position in one smooth movement. Clicking on the arrows at the ends of a bar causes a stepped, incremental change.

Click-in-image

The PTZ device can also be controlled using click-in-image movement, which can also be of relative or absolute type.

Absolute click-in-image movement means that the camera view will center on the absolute position that was clicked.

Relative click-in-image movement can be used when using the AXIS Media Control with Microsoft Internet Explorer. By clicking and holding the mouse button down in the image, the PTZ device moves the camera in that direction, relative to the center of the image. The further from the center the image is clicked, the greater the movement.

Focus and Iris Controls

The Focus and Iris (image brightness) can be adjusted manually by using the control bars, or they can be set for automatic adjustment, by clicking the Auto Iris and Auto Focus buttons.

Preset Positions

These presets are selected from the drop-down Source list on the Live View page and will move and/or zoom the camera to a pre-defined position, i.e. to cover an area of particular interest. Events can also be configured to go to preset positions when triggered. For information on setting up preset positions, please see the online help.

Preset Positions - a preset position is a pre-defined camera view than can be used to quickly move the camera to a specific location.

From Preset Position Setup, use the Pan, Tilt and Zoom (PTZ) controls to steer the camera to the required position. When satisfied with the camera's position, enter a descriptive name. The camera position, iris and focus settings are then saved as a preset position.

The position can be assumed at any time, by selecting the preset's name from the Preset positions drop-down list. Preset positions can be selected in Live View, from events, in Sequence mode and in the Guard Tour.

One position can be set as the Home position, which is readily accessible by clicking on the H button in both the Preset Position Setup window and the Live View window. The position's name will have (H) added, e.g. Office Entrance (H).

Guard Tour

A guard tour displays the video streams from different preset positions from cameras in the system, one-by-one, in a pre-determined order or randomly, and for configurable time periods. Once the preset position has been set, and added to the guard tour, the following settings can be made:

• View Time in seconds or minutes

• Move Speed - sets the speed of the Pan/Tilt movements to the preset position

• View Order (or Random)

Pan Tilt Zoom

For an overview of Pan Tilt Zoom controls, see page 25.

Limits

Define the pan, tilt, zoom and focus limits for the AXIS 231D+/232D+. Movements to the left and right, up and down can be restricted to narrow the area under surveillance. The near focus limit can be set to avoid focusing on objects too close to the camera.

Note: Once a limit has been saved, this position can not be exceeded by the AXIS 231D+/232D+ unless the values

have been reset and saved to a greater value first (i.e. reset the default values of the mechanical restrictions).

Move speed sets the speed of the camera's Pan/Tilt movements. The default setting is maximum speed.

Event Types

An Event Type is a set of parameters describing how and when the Network Dome Camera is to perform certain actions.

Example: If a door is opened, and an event

has been configured to act on this, the Network Dome Camera can e.g. record and save video images to an FTP server or send a notification email to a pre-configured email address with a pre-configured message. Video images can be sent as an attachment with the email.

Triggered Event

A Triggered event is activated from, e.g:

• a switch (doorbell) connected to an input port on the Network Dome Camera

• lost signal from the camera

• a manually activated action e.g. from an action button in the web interface

• on restart (reboot) after e.g. power loss

How to set up a triggered event

This example describes how to set the Network Dome Camera to upload images when the main door is opened:

1. Click Add triggered on the Event types page.

2. Enter a descriptive name for the event, e.g. Main door.

3. Set the priority - High, Normal or Low (see online help files).

4. Set the Respond to Trigger... parameters when the event is to be active, e.g. only after office hours

5. Select the trigger alternative from the Triggered by... drop-down list, e.g. an Input port with a connected sensor if the door is opened.

6. Set the When Triggered... parameters i.e. set what the Network Dome Camera is to do if the main door is opened e.g. upload images to an FTP server.

7. Click OK to save the Event in the Event Types list.

Please use the online help files for descriptions of each available option.

AXIS 231D+/232D+ - Event Configuration

Pre-trigger and Post-trigger buffers

This function is very useful when checking to see what happened immediately before and after a trigger, e.g. 2 minutes before and after a door has been opened.

Go to Event Types > Add Triggered... >

When Triggered... and check the Upload images checkbox to expand the web page

with the available options. Buffer size - up to 9 MB buffer. The

maximum length of time of the pre-/post-buffer depends on the image size and selected frame rate.

Include pre-trigger buffer - images stored internally in the server from the time immediately preceding the trigger. Check the box to enable the pre-trigger buffer, enter the desired length of time and specify the required image frequency.

Include post-trigger buffer - contains images from the time immediately after the trigger. Configure as for pre-trigger.

Note: If the pre- or post-buffer is too large for the internal memory, the frame rate will be reduced and individual

images may be missing. If this occurs, an entry will be created in the unit's log file.

Continue image upload (unbuffered) - enable the upload of images for a fixed length of time. Specify the length of time for the uploaded recording, in seconds, minutes or hours, or for as long as the trigger is active. Finally, set the desired image frequency to the maximum (the maximum available) or to a specified frame rate. The frame rate will be the best possible, but might not be as high as specified, especially if uploading via a slow connection.

2. Enter a descriptive name for the event, e.g. Scheduled email.

3. Set the priority (High, Normal or Low).

4. Set the Activation Time parameters (24h clock) when the event is to be active, e.g. start on Fridays at 18.00 with a duration of 62 hours.

5. Set the When Activate d. .. parameters i.e. set what the Network Dome Camera is to do at the specified time e.g. send uploaded images to an email address.

6. Click OK to save the Event in the Event Types list.

Please use the online help files for descriptions of each available option.

Port Status

Under Event Configuration > Port Status there is a list that shows the status for the connected inputs and outputs of the AXIS 231D+/232D+ for the benefit of the Operator who cannot access the System Options section.

Example: If the Normal state for a push button (e.g. doorbell) connected to an input is set to Open circuit - as

long as the button is not pushed, the state is inactive. If the push button is pushed, the state of the input changes to active.

HTTPS

For greater security, the AXIS 231D+/232D+ can be configured to use HTTPS (Hypertext Transfer Protocol over SSL (Secure Socket Layer)). That is, all communication that would otherwise go via HTTP will instead go via an encrypted HTTPS connection.

Certificate - to use HTTPS for communication with the AXIS 231D+/232D+, a Certificate must be created using one of the following methods:

• A self-signed certificate can be created in the network camera, but this does not guarantee the same level of security as an official certificate.

• An official certificate issued by a CA (Certificate Authority). A CA issues and manages security credentials and public keys for message encryption.

1. Click either Create self-signed certificate or Create Certificate Request and enter

the required information in the provided fields.

2. Click OK.

3. Create self-signed certificate generates and installs a certificate which will be

displayed under Installed Certificate. Create Certificate Request generates a PEM formatted request which you copy and send to a CA for signing. When the signed certificate is returned, click Install signed certificate... to install the certificate in the AXIS 231D+/232D+.

IP Address Configuration. the IP address of the AXIS 231D+/232D+ can be set

automatically via DHCP, or a fixed IP address can be set manually. DHCP is enabled by default. To use a fixed IP address, you must also enter the correct subnet mask and default router.

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 network camera when the IP address changes.

• Alternatively, if your DHCP server can update a DNS server, you can access the AXIS 231D+/232D+ by host name which is always the same, regardless of the IP address.

For more information, please refer to the online help files

DNS Configuration

DNS (Domain Name Service) provides the translation of host names to IP addresses on your network.

Obtain DNS server address via DHCP - automatically use the DNS server settings provided by the DHCP server. Click the View button to see the current settings.

Use the following DNS server address - enter the desired DNS server by specifying the following:

Domain name - enter the domain(s) to search for the host name used by the AXIS 231D+/232D+. Multiple domains can be separated by semicolons (;). The host name is always the first part of a Fully Qualified Domain Name, e.g. myserver is the host name in the Fully Qualified Domain Name myserver.mycompany.com where mycompany.com is the Domain name.

DNS servers - enter the IP addresses of the primary and secondary DNS servers.

Host Name Configuration

The AXIS 231D+/232D+ can be accessed using a host name, instead of an IP address. The host name is usually the same as the assigned DNS Name. It is always the first part of a Fully Qualified Domain Name and is always one word, with no period. For example, myserver is the host name in the Fully Qualified Domain Name myserver.mycompany.com.

The enable dynamic DNS updates allows you to alias a dynamic IP address to a static host name, allowing your computer to be more easily accessed from various locations on the Internet. Outside users can always access your server using the associated DNS name regardless of the WAN IP. The DNS server used by the user and/or the DNS server responsible for the domain in use must support RFC2136 and allow updates from the AXIS 231D+/232D+.

The TTL (Time To Live) value determines how long (in seconds) the reply from the DNS server should be remembered when checking that the domain name for the registered IP address is still valid. For more information, please see the online help

Link-Local Address

This is enabled by default and assigns the AXIS 231D+/232D+ an additional IP address for use with UPnP™. The AXIS 231D+/232D+ can have both a Link-Local IP and a static/DHCP-supplied IP address at the same time - these will not affect each other.

HTTP

The default HTTP port number (80) can be changed to any port within the range 1024-65535. This is useful for e.g. simple port mapping.

Page 38

AXIS 231D+/232D+ - System Options

RTSP

The RTSP protocol allows a connecting client to start an MPEG-4 stream. Enter the RTSP port number to use. The default setting is 554.

Network Traffic

The default setting is Auto-negotiate which means that the correct speed is automatically selected. If necessary, you can set the connection speed by selecting it from the drop-down list.

Maximum bandwidth - Specify, in Mbit/s or kbit/s, the maximum bandwidth that the network camera is allowed to use on your network. This is a useful function when connecting your network camera to busy or heavily loaded networks. The default setting is Unlimited.

Note: When using MPEG-4 as the video format, remember that setting a maximum bandwidth value here may

create problems for individual video streams if the maximum value is less than the sum of the bit rates set for the video streams.

For more information, please see the online help

SOCKS

SOCKS is a networking proxy protocol. The AXIS 231D+/232D+ can be configured to use a SOCKS server to reach networks on the other side of a firewall/proxy server. This functionality is useful if the AXIS 231D+/232D+ is located on a local network behind a firewall, but notifications, uploads, alarms, etc., need to be sent to a destination outside the local network (e.g. to the Internet ).

SMTP (email)

(Simple Mail Transfer Protocol) Enter the host names or addresses for your primary and secondary mail servers in the fields provided to enable event and error email messages from the AXIS 231D+/232D+ to predefined addresses, via SMTP.

AXIS 231D+/232D+ - 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.

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 and/or unicast MPEG-4 clients. Bandwidth affected.

• Simultaneous viewing of different streams (resolution, compression, etc.) by different clients. Frame rate and bandwidth affected.

• Accessing both Motion JPEG and MPEG-4 video streams simultaneously. Frame rate and bandwidth affected.

• Heavy usage of event settings affects the CPU load. Frame rate affected.

• Heavy network utilization due to poor infrastructure. Bandwidth affected.

• Viewing on poorly performing client PC’s lowers perceived performance. Frame rate affected.

Optimizing your system

To see the bandwidth and frame rate currently required by the video stream, the AXIS 231D+/232D+ 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) bandwidth in Kbps)

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.

Frame rates - Motion JPEG

The following test results show the frame rates in frames/second (fps) for Motion JPEG streams from the AXIS 231D+/232D+, using a compression level of 50%. Note that these values are guidelines only - actual values may vary.

fps (PAL) fps (NTSC)

4CIF 25/30 25/30

2CIF expanded 25/30 25/30

2CIF 25/30 25/30

CIF 25/30 25/30

QCIF 25/30 25/30

Frame rates - MPEG-4

The following test results show the frame rates in frames/second (fps) for MPEG-4 streams from the AXIS 231D+/232D+. Note that these values are guidelines only - actual values may vary.

The MPEG-4 test conditions:

• Compression level = 50%

• Video Object Type = Advanced Simple

• GOV structure = IP*

fps (PAL) fps (NTSC)

4CIF 17/21 17/21

2CIF expanded 17/21 17/21

2CIF 25/30 25/30

CIF 25/30 25/30

QCIF 25/30 25/30

*Note that setting the GOV structure to use “I-frames only” will increase the frame rate.

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

Page 52

AXIS 231D+/232D+ - Technical Specifications

There are also factors in the monitored scene that will affect the bandwidth. These are:

• the amount of motion

• the image’s complexity

• the lighting conditions.

For MPEG-4, if there is only limited bandwidth available, and if this is more important than the image quality, using a constant bit rate (CBR) is recommended. Use a variable bit rate (VBR) if the image quality needs to be maintained at a higher level. If supported on the network, consider also using MPEG-4 multicasting, as the bandwidth consumption will be much lower.
