LPR FAQs
What does LPR stand for? License plate recognition.
What is LPR? LPR is video-based content analysis (VCA) and recognition of vehicle license plates.
To read the characters in question, LPR uses optical character recognition on images aided by
specialized camera settings.
What is an LPR Server? An LPR Server handles LPR video from XProtect Corporate or XProtect
Enterprise. It turns this video into recognitions and sends these to the XProtect Event Server from
where it can be used for events and alarms. An LPR Server should be installed on a machine
especially allocated for the purpose.
What is an LPR camera? An LPR camera defines from where an LPR setup receives video (typically
a camera), and how this video is configured and processed. An LPR setup typically has several LPR
cameras. Each LPR camera requires an LPR Camera License.
What is a license plate library? A license plate library is a set of rules defining license plates of a
certain type and form as belonging to a certain country or region. In other words, it dictates plate and
character specifics (color, type, hight, spacing, and similar, which is used during the recognition
process). Each license plate library requires an LPR License Plate Library license.
What is a license plate list? A license plate list is a list that you create. License plate lists are
collections of license plates that you want your LPR solution to treat in a special way. Once you have
specified a list, you can set up events to recognize license plates on these lists and in this way trigger
your XProtect Corporate or XProtect Enterprise events. It is also possible to create alarms built/based
on LPR events.
