2N Access Commander version 3.6.1 (May 2026)

2N Access Commander version 3.6 introduces a faster way to configure devices through device templates, a centralised call log for intercoms, a dedicated Company Admin role for managing organisation-level settings, and several quality-of-life improvements throughout the system.

Bugs fixed in 3.6.1:

Addresses a critical bug that a ects a small number of Access Commander Box installations and My2N app pairing.

New Features: 

Device Templates

Admins can now save and edit the configuration file of any 2N OS–based device and apply it to other devices individually or in bulk.

• Create templates from an existing device, a configuration file, or a device backup. 
• Templates can include only selected parts of the configuration, allowing controlled or 
  limited deployments. 
• Before a template is applied, Access Commander automatically creates a backup of the 
  target device. 
• Templates can be downloaded and uploaded to existing or future Access Commander 
  installations.

Important: 

• Templates are an advanced feature. Always review the configuration parameters and 
  values before applying a template. 
• Some parameters are automatically excluded (for example, static IP address) to prevent 
  unwanted duplication. 
• Certain parameters are highlighted with warnings; verify these carefully before 
  deployment. 
• Templates are supported only on 2N OS–based IP devices. They are not supported on 2N 
  Electronic Locks or 2N Indoor Touch. 

Call logs

Call logs provide administrators with a single, unified view of incoming and outgoing calls from all intercoms and elevator communication devices. 

• One consolidated list: Calls from every managed device appear together. 
• Door unlock during a call: If a door is opened during a call, the event is recorded in both 
  the Call log and the Access log, and clearly marked with an icon. 
• Optional CAM logs: Enable CAM logs to capture images from intercoms when a call 
  begins. 

Please note: If both the caller and receiver are managed by Access Commander, the system 
may record two entries for the same call — one outgoing and one incoming. Call logs are 
created in Access Commander once a call is terminated.

Company admin role  

The new Company Admin role gives designated users control over company-specific settings that previously required full administrator rights. This role can be combined with others such as User Manager or Visitor Manager, depending on requirements. Company Admin rights include: 

• Viewing system log events related to their company. 
• Managing company details such as the name, default language, working hours, 
  holidays, and visitor settings. 
• Creating and editing email templates. 
• Managing LDAP user synchronisation. 
• Initiating lockdown of company devices (intercoms and access units). 

Other improvements:  

Pairing with the My2N mobile app is now faster and more secure. Users can pair the app via a QR code displayed in Access Commander or from a link or QR code sent by email. (Supported on devices running FW 2.50/3.0 and higher).

• Access Commander can now be discovered on the local network using the 2N IP Utility 
  application, together with 2N OS and Axis devices. (Windows only; the Access 
  Commander IP address cannot be configured through the tool). 
• mDNS domain name support added. Access Commander can now be reached on the 
  local network at https://accesscommander.local 
• Network discovery features (mDNS domain and 2N IP Utility) can be disabled in 
  Settings>Configuration. 
• The linux console welcome message has been updated to include the mDNS domain in 
  addition to the IP address. 
• Access Commander now supports MIFARE DESFire cards in use by a third-party. Cards 
  must support anonymous application creation. 

Required Device Firmware Versions for Full Feature Support 

• 2N IP Intercoms: 2.50.x/3.2.x 
• 2N Access Units: 2.50.x/3.2.x 
• 2N Answering Units: 2.50.x/3.2.x 
• 2N Emergency Elevator Communicators: 3.2.x 

Note - some older 2N devices cannot support versions higher than 2.50.

• Cached DNS entries for SIP registrars now expire immediately and correctly when the registrar IP address changes, preventing registration failures.
• Fixed an issue where devices could lose and reacquire their IP address via DHCP twice after a factory reset and subsequent reboots.
• Resolved a device crash that could occur when sending emails using specific SMTP server configurations.
• The `snmpget` function now works correctly on devices using SNMPv3.
• Devices now correctly process `Too Brief` SIP responses during registration and immediately apply the updated expiry period.
• Fixed device crashes caused by specific malformed or non-standard ONVIF requests.
• Corrected an issue where video resolution could be incorrectly limited when selecting lower bitrate settings for the H.265 codec.
• Added a limited-range mode to the WaveKey opening algorithm to prevent unintended door openings from excessive distance.
• PEAP MSCHAPv2 authentication is now fully functional and reliable across all supported models.
