There are several possible reasons why the gate does not open when you try to access with ANPR.
Definition: Automatic number-plate recognition (ANPR), is one of the entrance methods proposed by Izix on some parking lots. The camera reads your license plate; the software determines if this license plate has the right to enter the parking lot and, if so, triggers the gate to open.
If the gate did not open, please firstly contact your parking/office administrator. They have access to the logs and will be able to identify the issue.
Also consider using an alternative access method.
There is always at least a second entrance method enabled on each parking lot (e.g. app, code, etc.). See here to learn about the Izix app.

1. How does ANPR work?
The access with license plate recognition is only possible on a series of limited parking lots. You can check if access to the parking lot is possible through license plate recognition in the description of your access (check out for the 
pictogram)
To enable access to the parking lot based on your license plate, you need to complete and maintain your license plate information up to date in your profile. When this information is completed, you can access the parking lot by simply presenting your vehicle in front of the gate.
The camera will read your license plate and communicate it to the system, that will check if you have a valid access to the parking lot. If yes, the system will inform the gate management system that the gate can be opened. If there is no valid access (e.g. no booking is made, all First come first serve spots are busy, etc.), the gate will not open.
In some rare cases it is possible that the camera is not able to read your license plate, mostly due to factors outside of our control. In this case, the information is not read and not send to the system: no gate opening can be triggered.
2. Reasons why a gate may not open with ANPR
- Lack of valid access: missing booking, full parking, you are trying to access outside of the allowed schedule or alike --> Check your valid accesses here
- Missing licence plate: Did you register your licence plate on your Izix profile? --> Check and adjust your licence plate here
- Car positioning: Was the positioning of the car adequate? As a reminder, you have to position your car in the field of vision of the cameras (4-8m before the gate) and drive slowly (5km/h) until you reach the parking access gates. Once in front of the gates, stop and wait a few seconds.
- License plate state: Is your car plate readable: is it clean? Is it highly reflective ? Is it personalized or does it includes "0", "Q", "O" characters? Sensors might have trouble differentiating some characters and reading in specify conditions
