Certificates are used to authenticate devices on a network. The device supports two types of certificates:

  • Client/server certificates

    A client/server certificate validates the device’s identity, and can be self-signed or issued by a Certificate Authority (CA). A self-signed certificate offers limited protection and can be used before a CA-issued certificate has been obtained.

  • CA certificates

    You can use a CA certificate to authenticate a peer certificate, for example to validate the identity of an authentication server when the device connects to a network protected by IEEE 802.1X. The device has several pre-installed CA certificates.

These formats are supported:

  • Certificate formats: .PEM, .CER, and .PFX

  • Private key formats: PKCS#1 and PKCS#12


If you reset the device to factory default, all certificates are deleted. Any pre-installed CA certificates are reinstalled.

Add certificate : Click to add a certificate.

  • Trusted Platform Module 2.0 (CC EAL4+, FIPS 140-2 Level 2): Select to use TPM 2.0 for secure keystore.

IEEE 802.1x and IEEE 802.1AE MACsec

IEEE 802.1x is an IEEE standard for port-based network admission control providing secure authentication of wired and wireless network devices. IEEE 802.1x is based on EAP (Extensible Authentication Protocol).

To access a network protected by IEEE 802.1x, network devices must authenticate themselves. The authentication is performed by an authentication server, typically a RADIUS server (for example, FreeRADIUS and Microsoft Internet Authentication Server).


When configured without a CA certificate, server certificate validation is disabled and the device tries to authenticate itself regardless of what network it is connected to.

When using a certificate, in Axis' implementation, the device and the authentication server authenticate themselves with digital certificates using EAP-TLS (Extensible Authentication Protocol - Transport Layer Security).

To allow the device to access a network protected through certificates, you must install a signed client certificate on the device.

Authentication method: Select an EAP type used for authentication. The default option is EAP-TLS. EAP-PEAP/MSCHAPv2 is a more secure option.

Client certificate: Select a client certificate to use IEEE 802.1x. The authentication server uses the certificate to validate the client’s identity.

CA certificate: Select CA certificates to validate the authentication server’s identity. When no certificate is selected, the device tries to authenticate itself regardless of what network it is connected to.

EAP identity: Enter the user identity associated with the client certificate.

EAPOL version: Select the EAPOL version that is used in the network switch.

Use IEEE 802.1x: Select to use the IEEE 802.1x protocol.

IEEE 802.1AE MACsec

IEEE 802.1AE MACsec is an IEEE standard for media access control (MAC) security that defines connectionless data confidentiality and integrity for media access independent protocols.

The settings are only available if you use EAP-TLS as the authentication method:


  • Dynamic CAK / EAP-TLS: The default option. After a secured connection, the device checks for MACsec on the network.

  • Static CAK / pre-shared key (PSK): Select to set the key name and value to connect to the network.

The settings are only available if you use EAP-PEAP/MSCHAPv2 as the authentication method:

  • Password: Enter the password for your user identity.

  • Peap version: Select the Peap version that is used in the network switch.

  • Label: Select 1 to use client EAP encryption; select 2 to use client PEAP encryption. Select the Label that the network switch uses when using Peap version 1.


Add user: Click to add a new user. You can add up to 100 users.

Username: Enter a unique username.

New password: Enter a password for the user. Passwords must be 1 to 64 characters long. Only ASCII printable characters (code 32 to 126) are allowed in the password, for example letters, numbers, punctuation, and some symbols.

Repeat password: Enter the same password again.


  • Administrator: Has full access to all settings. Administrators can also add, update, and remove other users.

  • Operator: Has access to all settings except:

    • All System settings.

  • Subnet mask
  • 802.1X settings
  • O3C settings

Factory default: Return all settings to the factory default values. Afterwards you must reset the IP address to make the device accessible.


All Axis device firmware is digitally signed to ensure that you only install verified firmware on your device. This further increases the overall minimum cybersecurity level of Axis devices. For more information, see the white paper “Signed firmware, secure boot, and security of private keys” at

Firmware upgrade: Upgrade to a new firmware version. New firmware releases can contain improved functionality, bug fixes, and completely new features. We recommend you to always use the latest release. To download the latest release, go to

  • When you upgrade, you can choose between three options:
  • Standard upgrade: Upgrade to the new firmware version.

  • Factory default: Upgrade and return all settings to the factory default values. When you choose this option, you can’t revert to the previous firmware version after the upgrade.

  • Autorollback: Upgrade and confirm the upgrade within the set time. If you don’t confirm, the device reverts to the previous firmware version.

Firmware rollback: Revert to the previously installed firmware version.


Download configuration file: Select which settings you want to include in the configuration file. The file won't include certificates or private keys.

Upload configuration file: The uploaded configuration file overwrites the existing configuration within the same area. For example: if your file only contains information about video, the system settings won't be affected. The configuration file doesn’t include certificates or private keys. If you want other certificates than the default self-signed ones, you need to set them manually.

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

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


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 older MPEG formats. 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.


Reset to factory default settings


Use the reset to factory default function with caution. A reset to factory default resets all settings, including the IP address, to the factory default values.

  1. Go to Maintenance > Factory default.

  2. Click Default.

  3. Click Restore all.

It is also possible to reset parameters to factory default with the restart button. With the device turned on, press and hold the restart button for 10 seconds.

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 version

Firmware is the software that determines the functionality of network devices. When you troubleshoot a problem, we recommend you to start by checking the current firmware version. The latest firmware version might contain a correction that fixes your particular problem.

To check the current firmware:

  1. Go to the device’s web interface > Status.

  2. See the firmware version under Device info.

Upgrade the firmware

  • Preconfigured and customized settings are saved when you upgrade the firmware (provided that the features are available in the new firmware) although this is not guaranteed by Axis Communications AB.
  • Make sure the device remains connected to the power source throughout the upgrade process.

When you upgrade the device 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 you upgrade the firmware. To find the latest firmware and the release notes, go to

  1. Download the firmware file to your computer, available free of charge at

  2. Log in to the device as an administrator.

  3. Go to Maintenance > Firmware upgrade and click Upgrade.

  4. When the upgrade has finished, the product restarts automatically.

You can use AXIS Device Manager to upgrade multiple devices at the same time. Find out more at

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 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 can’t be accessed from a browser

Can’t 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 System > Date and time.

Performance considerations

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.

  • 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.
