2N devices can now use recognized license plates as another credential for entry or exit. This function can be enabled on any device that supports “Door” functionality. License plates may be assigned to a user and their validity is controlled by the same access rules as their other credentials.


License plate recognition (LPR) works outside of Access Profiles set in Hardware>Door>Entry or Exit Rules, and as such can’t be combined with other credentials for combined authentication.

2N device configuration

  1. Set Camera HTTP API to Unsecured (TCP) Digest
  2. Set Account 1 to match credentials used in Vega camera and enable Access Control privilege
  3. Enable License Plate Recognition on 2N device
  4. Add user and enter LP of car as an access credential in to Car Fleet management

2N® Access Commander configuration (optional)


When a 2N device is connected to 2N® Access Commander, then most of its settings are managed by it. Thus, LPR settings will be managed by 2N® Access Commander, but still you have to configure the device’s HTTP API credentials as those are device dependent.

  1. Configure your 2N® Access Commander as you normally would. Then open details of the device you already prepared for LPR

    and make sure it has Lift Control turned off and that it’s assigned to the proper zone.
  2. Then go to this Zone’s detail and enable License Plate Authentication.
  3. Users can have their license plates assigned

    under Accesses>Car License Plates, click ADD, enter one or more license plates, and confirm by clicking create.

  4. Verify that this user is assigned to the correct group

    and create an Access Rule for it.
  5. Optionally, if you’d like to get photos of recognized license plates, you can create + NEW CAM LOGS. Name the log accordingly, select “Car license plate recognized” and click create.

    Then ADD all devices you want to receive photos from to this CAM Log.
  6. Once everything is configured, Access Logs will show up once a license plate is recognized.
