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 Access Commander configuration (optional)
Version 3.0+
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.
-
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.
-
Then go to this Zone’s detail and enable License Plate Authentication.
-
Users can have their license plates assigned under Overview → Credentials section, click Add Credential, enter one or more license plates, and confirm by clicking create.
-
Verify that this user is assigned to the correct group
and create an Access Rule for it.
-
Optionally , if you’d like to get photos of recognized license plates, you can create + CAM LOGS . Name the log accordinglyand after creaion select the Car license plate recognised.
-
Then ADD all devices you want to receive photos from to this CAM Log.
Once everything is configured, Access Logs will show up once a license plate is recognized.
