AO-20W  Wiegand Converter

The Wiegand protocol is commonly used in traditional access control systems, which grant access to drivers based on their badge with valid Wiegand ID numbers. In order to easily upgrade existing access control systems with the power of VIVOTEK LPR cameras, VIVOTEK’s onboard ANPR software can link license plates to specific Wiegand ID numbers (eg. driver’s badge). In the meantime, the VIVOTEK Wiegand converter can convert the Ethernet signal to Wiegand output signal in order to work with the existing access control system.

Moreover, with VIVOTEK’s ANPR software, you can also easily configure a mapping list to link plate numbers to specific ID numbers and set specific actions to individual groups.
