  • Make sure to select the capture mode that has the highest resolution.

  • Set the compression as low as possible.

  • Select MJPEG streaming.

  • Turn off Zipstream functionality.

Stabilize a shaky image with Electronic Image Stabilization (EIS)

Electronic Image Stabilization (EIS) can be used in environments where the product is mounted in an exposed location and subject to vibrations, for example, wind or passing traffic. Turn on EIS to get a smoother and steadier image without blur.

EIS also reduces the file size of the compressed image and lowers the bitrate of the video stream.

Note

When EIS is turned on the image is cropped slightly, lowering the maximum resolution.

Capture modes

Capture mode defines the maximum resolution and maximum frame rate available in the Axis product. The capture mode also affects light sensitivity. A capture mode with a high maximum frame rate has reduced light sensitivity and vice versa.

Which capture mode to choose depends on the requirements of frame rate and resolution for the specific surveillance setup. For specifications about available capture modes, see the product’s datasheet at axis.com.

Overlays

Note

Overlays are not included in the video stream when using SIP calls.

Note

Image and text overlay will not be displayed on video stream over HDMI.

Note

Image and text overlay will not be displayed on video stream over SDI.

Overlays are superimposed over the video stream. They are used to provide extra information during recordings, such as a timestamp, or during product installation and configuration. You can add either text or an image.

Streaming and storage

Video compression formats

Decide which compression method to use based on your viewing requirements, and on the properties of your network. The available options are:

Motion JPEG

Note

To ensure support for the Opus audio codec, the Motion JPEG stream is always sent over RTP.

Motion JPEG, or MJPEG, is a digital video sequence that is made up of a series of individual JPEG images. These images are then displayed and updated at a rate sufficient to create a stream that shows constantly updated motion. For the viewer to perceive motion video the rate must be at least 16 image frames per second. Full motion video is perceived at 30 (NTSC) or 25 (PAL) frames per second.

The Motion JPEG stream uses considerable amounts of bandwidth, but provides excellent image quality and access to every image contained in the stream.

H.264 or MPEG-4 Part 10/AVC

Note

H.264 is a licensed technology. The Axis product includes one H.264 viewing client license. To install additional unlicensed copies of the client is prohibited. To purchase additional licenses, contact your Axis reseller.

H.264 can, without compromising image quality, reduce the size of a digital video file by more than 80% compared to the Motion JPEG format and by as much as 50% compared to the MPEG-4 standard. This means that less network bandwidth and storage space are required for a video file. Or seen another way, higher video quality can be achieved for a given bitrate.

H.265 or MPEG-H Part 2/HEVC

Note

H.265 is licensed technology. The Axis product includes one H.265 viewing client license. To install additional unlicensed copies of the client is prohibited. To purchase additional licenses, contact your Axis reseller.

How do Image, Stream, and Stream profile settings relate to each other?

The Image tab contains camera settings that affect all video streams from the product. If you change something in this tab, it immediately affects all video streams and recordings.

The Stream tab contains settings for video streams. You get these settings if you request a video stream from the product and don’t specify for example resolution, or frame rate. When you change the settings in the Stream tab, it doesn’t affect ongoing streams, but it will take effect when you start a new stream.

The Stream profiles settings override the settings from the Stream tab. If you request a stream with a specific stream profile, the stream contains the settings of that profile. If you request a stream without specifying a stream profile, or request a stream profile that doesn't exist in the product, the stream contains the settings from the Stream tab.

Bitrate control

With bitrate control, you can manage the bandwidth consumption of your video stream.

Variable bitrate (VBR)
With variable bitrate, the bandwidth consumption varies based on the level of activity in the scene. The more activity in the scene, the more bandwidth you need. You are guaranteed constant image quality but it requires storage margins.

Maximum bitrate (MBR)
With maximum bitrate, you can set a target bitrate to handle bitrate limitations in your system. You may see a decline in image quality or frame rate when the instantaneous bitrate is kept below the specified target bitrate. You can choose to either prioritize image quality or frame rate. We recommend that you configure the target bitrate to a higher value than the expected bitrate. This gives you a margin for additional complexity that needs to be captured.

  1. Target bitrate

Average bitrate (ABR)
With average bitrate, the bitrate is automatically adjusted over a longer timescale. This is so you can meet the specified target and provide the best video quality based on your available storage. Bitrate is higher in scenes with a lot of activity, compared to static scenes. You are more likely to get better image quality when needed when using the average bitrate option. You can define the total storage required to store the video stream for a specified amount of time (retention time) when image quality is adjusted to meet the specified target bitrate. Specify the average bitrate settings in one of the following ways:

  • To calculate the estimated storage need, set the target bitrate and the retention time.

  • To calculate the average bitrate, based on available storage and required retention time, use the target bitrate calculator.

    1. Target bitrate
    2. Actual average bitrate
  • You can also turn on maximum bitrate and specify a target bitrate within the average bitrate option.

How to activate an application licence code on a device

Autotracking

With autotracking, the camera automatically zooms in on and tracks moving objects, for example a vehicle or a person. You can manually select an object to track, or set up trigger areas and let the camera detect moving objects. The application is best suited for open areas with no obscuring objects and where movement is unusual. When the camera doesn't track an object, it returns to its home position.

Important
  • Autotracking is designed for areas with a limited amount of movement.

How to choose audio input type

Unbalanced inputs are the most commonly used as they are affordable, easily available and compatible with most inputs thanks to the 3.5 mm connector. Use the Unbalanced line input for signals coming from a media player or computer.

However, some considerations need to be made when installations require a longer cable between the source and the camera, or if there is interference from external sources. This is because the cables can act like an antenna and pick up unwanted noise and interference from external sources such as power cables or even wireless devices. Always make sure that your unbalanced cable is no longer than it needs to be, and plan the cable run carefully. For example, do not run them parallel to other cables, especially power cables. This is especially true for unbalanced microphones as all microphone level inputs need to be amplified considerably, resulting in the amplification of the unwanted noise and interference. Most small unbalanced (electret type) microphones require a small voltage to power them. In this case, select the Powered unbalanced microphone option.

When longer cable runs are required, and if your equipment at each end is compatible, using an XLR input with a balanced cable is highly recommended. Apart from allowing the use of more specialized microphones, this professional system rejects outside interference, allowing for much longer cable runs. Select the Balanced microphone input when using dynamic type microphones. If you are using a condenser type microphone, they will typically require a 48 V phantom power supply. This can be provided by the camera through the XLR connector when Phantom-powered balanced microphone is selected.

Troubleshooting

Reset to factory default settings

Important

Reset to factory default should be used with caution. A reset to factory default resets all settings, including the IP address, to the factory default values.

To reset the product to the factory default settings:

  1. Disconnect power from the product.

  2. Press and hold the control button while reconnecting power. See Product overview.

  3. Keep the control button pressed for 15–30 seconds until the status LED indicator flashes amber.

  4. Release the control button. The process is complete when the status LED indicator turns green. The product has been reset to the factory default settings. If no DHCP server is available on the network, the default IP address is 192.168.0.90.

  5. Use the installation and management software tools to assign an IP address, set the password, and access the video stream.

    The installation and management software tools are available from the support pages on axis.com/support.

It is also possible to reset parameters to factory default through the web interface. Go to Settings > System > Maintenance and click Default.

Firmware options

Axis offers product firmware management according to either the active track or the long-term support (LTS) tracks. Being on the active track means continuously getting access to all the latest product features, while the LTS tracks provide a fixed platform with periodic releases focused mainly on bug fixes and security updates.

Using firmware from the active track is recommended if you want to access the newest features, or if you use Axis end-to-end system offerings. The LTS tracks are recommended if you use third-party integrations, which are not continuously validated against the latest active track. With LTS, the products can maintain cybersecurity without introducing any significant functional changes or affecting any existing integrations. For more detailed information about Axis product firmware strategy, go to axis.com/support/firmware.

Check the current firmware

Firmware is the software that determines the functionality of network devices. One of your first actions when troubleshooting a problem should be to check the current firmware version. The latest version may contain a correction that fixes your particular problem.

To check the current firmware:

  1. Go to the product’s webpage.

  2. Click the help menu .

  3. Click About.

Upgrade the firmware

Important

Preconfigured and customized settings are saved when the firmware is upgraded (provided that the features are available in the new firmware) although this is not guaranteed by Axis Communications AB.

Important

Make sure the product remains connected to the power source throughout the upgrade process.

Note

When you upgrade the product with the latest firmware in the active track, the product receives the latest functionality available. Always read the upgrade instructions and release notes available with each new release before upgrading the firmware. To find the latest firmware and the release notes, go to axis.com/support/firmware.

AXIS Device Manager can be used for multiple upgrades. Find out more at axis.com/products/axis-device-manager.

How to upgrade the firmware
  1. Download the firmware file to your computer, available free of charge at axis.com/support/firmware.

  2. Log in to the product as an administrator.

  3. Go to Settings > System > Maintenance. Follow the instructions on the page. When the upgrade has finished, the product restarts automatically.

Technical issues, clues and solutions

If you can’t find what you’re looking for here, try the troubleshooting section at axis.com/support.

Problems upgrading the firmware

Firmware upgrade failure

If the firmware upgrade fails, the device reloads the previous firmware. The most common reason is that the wrong firmware file has been uploaded. Check that the name of the firmware file corresponds to your device and try again.

Problems after firmware upgrade

If you experience problems after a firmware upgrade, roll back to the previously installed version from the Maintenance page.

Problems setting the IP address

The device is located on a different subnet

If the IP address intended for the device and the IP address of the computer used to access the device are located on different subnets, you cannot set the IP address. Contact your network administrator to obtain an IP address.

The IP address is being used by another device

Disconnect the Axis device from the network. Run the ping command (in a Command/DOS window, type ping and the IP address of the device):

  • If you receive: Reply from <IP address>: bytes=32; time=10... this means that the IP address may already be in use by another device on the network. Obtain a new IP address from the network administrator and reinstall the device.

  • If you receive: Request timed out, this means that the IP address is available for use with the Axis device. Check all cabling and reinstall the device.

Possible IP address conflict with another device on the same subnet

The static IP address in the Axis device is used before the DHCP server sets a dynamic address. This means that if the same default static IP address is also used by another device, there may be problems accessing the device.

The device cannot be accessed from a browser

Cannot log in

When HTTPS is enabled, ensure that the correct protocol (HTTP or HTTPS) is used when attempting to log in. You may need to manually type http or https in the browser’s address field.

If the password for the user root is lost, the device must be reset to the factory default settings. See Reset to factory default settings.

The IP address has been changed by DHCP

IP addresses obtained from a DHCP server are dynamic and may change. If the IP address has been changed, use AXIS IP Utility or AXIS Device Manager to locate the device on the network. Identify the device using its model or serial number, or by the DNS name (if the name has been configured).

If required, a static IP address can be assigned manually. For instructions, go to axis.com/support.

Certificate error when using IEEE 802.1X

For authentication to work properly, the date and time settings in the Axis device must be synchronized with an NTP server. Go to Settings > System > Date and time.

The device is accessible locally but not externally

To access the device externally, we recommend using one of the following applications for Windows®:

  • AXIS Companion: free of charge, ideal for small systems with basic surveillance needs.

  • AXIS Camera Station: 30-day trial version free of charge, ideal for small to mid-size systems.

For instructions and download, go to axis.com/vms.

Problems with streaming

Multicast H.264 only accessible by local clients

Check if your router supports multicasting, or if the router settings between the client and the device need to be configured. The TTL (Time To Live) value may need to be increased.

No multicast H.264 displayed in the client

Check with your network administrator that the multicast addresses used by the Axis device are valid for your network.

Check with your network administrator to see if there is a firewall preventing viewing.

Poor rendering of H.264 images

Ensure that your graphics card is using the latest driver. The latest drivers can usually be downloaded from the manufacturer’s website.

Color saturation is different in H.264 and Motion JPEG

Modify the settings for your graphics adapter. Go to the adapter’s documentation for more information.

Lower frame rate than expected

  • See Performance considerations.

  • Reduce the number of applications running on the client computer.

  • Limit the number of simultaneous viewers.

  • Check with the network administrator that there is enough bandwidth available.

  • Lower the image resolution.

  • Log in to the device’s webpage and set a capture mode that prioritizes frame rate. Changing the capture mode to prioritize frame rate might lower the maximum resolution depending on the device used and capture modes available.

  • The maximum frames per second is dependent on the utility frequency (60/50 Hz) of the Axis device.

Can't select H.265 encoding in live view

Web browsers do not support H.265 decoding. Use a video management system or application supporting H.265 decoding.

Performance considerations

When setting up your system, it is important to consider how various settings and situations affect the performance. Some factors affect the amount of bandwidth (the bitrate) required, others can affect the frame rate, and some affect both. If the load on the CPU reaches its maximum, this also affects the frame rate.

The following factors are the most important to consider:

  • High image resolution or lower compression levels result in images containing more data which in turn affects the bandwidth.

  • Rotating the image in the GUI will increase the product's CPU load.

  • Access by large numbers of Motion JPEG or unicast H.264 clients affects the bandwidth.

  • Simultaneous viewing of different streams (resolution, compression) by different clients affects both frame rate and bandwidth.

    Use identical streams wherever possible to maintain a high frame rate. Stream profiles can be used to ensure that streams are identical.

  • Accessing Motion JPEG and H.264 video streams simultaneously affects both frame rate and bandwidth.

  • Heavy usage of event settings affects the product’s CPU load which in turn affects the frame rate.

  • Using HTTPS may reduce frame rate, in particular if streaming Motion JPEG.

  • Heavy network utilization due to poor infrastructure affects the bandwidth.

  • Viewing on poorly performing client computers lowers perceived performance and affects frame rate.

  • Running multiple AXIS Camera Application Platform (ACAP) applications simultaneously may affect the frame rate and the general performance.
