●
Function library in C: dynamically linked library for Windows and GNU/Linux that
provides a function oriented vision of the system. It transparently manages simultaneous
communication with various units and allows programming with C while keeping the high
level vision provided by the C++ library. It can be used with both C and C++ languages.
●
Through SmartLPR ® Access-specific UDP protocol: provides the protocol definitions
used in communication in a header file; it also provides help functions and C samples.
1.7. Access control, white lists and Wiegand protocol
SmartLPR ® Access offers the possibility to upload into the unit a list of license plates, each of
them associated to an identifier. This feature allows comparing the license plate of the vehicle
arriving at the control point of the facility with the license plates included in the list. If the license
appears on the list, the unit sends the identifier associated with the vehicle through Wiegand
protocol. This way, the license plate reader acts as a “virtual” card reader.
White list & digital output:
The white list loaded can also be used to activate the digital output of the unit in case the license
plate found appears on the list. There are 3 possible choices (you can configure them in the
“Advanced settings” in the “Configuration” web page of the unit):
1. NEVER: The digital output will never be activated
2. OFFLINE: The digital output will activate when the external communications of the unit are
lost. This way, the unit acts as a stand-alone, “back-up” mechanism in case the access control
management system fails.
3. ALWAYS: The digital output will always activate. This way SmartLPR ® Access is completely
autonomous.
