Korean video surveillance specialists Hanwha Techwin, in partnership with data analytics experts FF Group, has launched a comprehensive suite of ALPR-based (Automatic License Plate Recognition) intelligent traffic management systems.
The systems range from car park access control for business applications to large scale city-wide systems which enable local authorities to keep people safe, as well as detect illegally parked vehicles and other traffic infringements. The FF Group’s ALPR application, which is effective with all European license plate formats, has been integrated into two of Hanwha’s Wisenet cameras. As a result, the Wisenet SNO-6095RH/FNP and XNO-6120R/FNP ALPR cameras can offer recognition accuracy of more than 95%, whatever the environmental conditions, and even when vehicles are moving at speeds of up to 93mph (150km/h).
Users can define up to 2,000 number plates in a ‘black and white’ list to automatically authorize or decline access to a site or car parking area, with each camera able to monitor up to three lanes of traffic. Recorded events include entry/exit activity and direction of vehicles. Alerts can be generated for crime prevention purposes, such as reducing incidents of non-payment at gas stations. For large car parks, shopping centers and other commercial sites where there is significant traffic movement, the single-site Wisenet ALPR server system provides a highly efficient and scalable option. It can simultaneously monitor images of vehicle traffic activity from up to 32 cameras, with online alerting, access control and usage analysis among the additional benefits.
Wisenet ALPR is also available in a range of cloud-based systems designed for multi-camera and multi-site applications. Providing ‘intelligent’ data analysis and reporting, these include:
Number Plate – reports include a photo of number plates, entry/exit timing and push notifications and alerts; Car Park – this allows security personnel to have strict control over which vehicles have access to a site’s sensitive areas, such as loading bays. Reports generated include the level of car park occupancy, the number of free spaces, duration of stay and frequency of visits. It can also synchronize data between multiple sites; City Traffic – located at city center intersections and main roads, the system provides local authorities and police with the license plate numbers of vehicles involved in traffic lane or parking infringements. It also offers access to real-time traffic flow data, such as the average speed and the number of vehicles on the roads. More in-depth analysis for longer term planning comes from the data that is gathered from everyday drivers who travel into specific areas.
