The Digifort vehicle License Plate Reading (LPR) system is described as a multi-channel, license module operating within its open-platform VMS (video management software).
It offers identification and categorisation of white or black-listed license plates and is for use in vehicle access control; traffic enforcement; toll collection positions; border crossings; and general site management applications. The Digifort LPR license applies to a server CPU core, not a camera channel. If the LPR is triggered by motion, two channels are enabled by a single core license. If an external, physical trigger is used to capture a single video image, reducing server processing overheads, up to 20 LPR channels can be in use, also by a single core license.
Francois Levy, Digifort Business Development Director for EMEA, says: “The Digifort LPR system is typically used to control vehicle access to a site through automated barriers or gates. Its user-configured, management database enables categories such as staff, stolen cars, site visitors, delivery vehicles, unrecognised plates and even “followed vehicles” to be triggers. Corresponding alarm actions can be scheduled for different outcomes by time of day or week.
“The LPR system recognises a plate’s characters and registers the plate on a management database, or in an external folder, with date, time and camera information tags. The database can be synchronised with external databases, such as from the police or DVLA, with associated vehicle owner information, if available. Plate data can also be shared between numerous, multi-channel, Digifort systems, across many sites.
“Digifort can read plates accurately on fast-moving vehicles and allow incoming and outgoing plate cameras to be set, to establish vehicle duration times, as used in car park ticketing. Surrounding cameras can also correlate with the primary, plate-capture cameras to provide additional video data, such as the front, side or cab of a vehicle.”
A suspect plate event can trigger a visual and audible warning; higher recorded video resolution and frame rate; and users can be told by email, text or SMS. A “mask” facility allows users to apply alarm rules to groups of plates and specify plate retention times. Automatic server failover is an option for mission-critical applications and plate recognition accuracy is measured to help users at camera set-up. An unlimited number of secure client PCs, tablets and smartphones can access and view the system. Visit www.digifort.com.
