Image quality

Color palettes

Color palettes applied to thermal images help the human eye distinguish image details. The colors in the palette are artificially created pseudocolors that emphasize temperature differences.

The product has several color palettes to choose from. If an operator watches the video stream, you can choose any of the palettes. If the video stream is only used by applications, select the white-hot palette.

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.


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

  1. Go to Settings > Image > Image correction.

  2. Turn on EIS.

Streaming and storage

Bitrate control

Bitrate control helps you to manage the bandwidth consumption of your video stream.

Variable bitrate (VBR)Variable bitrate allows the bandwidth consumption to vary depending on the level of activity in the scene. The more activity, the more bandwidth you need. With variable bitrate you are guaranteed constant image quality, but you need to make sure you have storage margins.

Maximum bitrate (MBR)Maximum bitrate lets you set a target bitrate to handle bitrate limitations in your system. You might see a decline in image quality or frame rate as the instantaneous bitrate is kept below the specified target bitrate. You can choose to prioritize either 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 in case there is a high level of activity in the scene.

  1. Target bitrate

Average bitrate (ABR)With average bitrate, the bitrate is automatically adjusted over a longer period of time. 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 in scenes with a lot of activity if you use 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.
    1. Target bitrate
    2. Actual average bitrate

Reduce bandwidth and storage


If you reduce the bandwidth it can result in loss of details in the picture.

  1. Go to live view and select H.264.

  2. Go to Settings > Stream.

  3. Do one or more of the following:

    • Turn on dynamic GOP and set a high GOP length value.

    • Increase the compression.

    • Turn on dynamic FPS.

    The installation and management software tools are available from the support pages on

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

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


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.


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


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

Technical issues, clues and solutions

If you can’t find what you’re looking for here, try the troubleshooting section at

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 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

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

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.

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.

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

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.

  • Using palettes affects the product’s CPU load which in turn affects the frame rate.
