Automatic Number Plate Recognition (ANPR) is often spoken of as an application for collecting license plate data of vehicles travelling on highways and city streets. As such, car park management is a sometimes-overlooked beneficiary of ANPR technology.
Installing ANPR cameras in car parks can provide a high return on investment for residential complexes, school campuses, car parks with time restrictions, or any parking facility that would normally require a patrol to make rounds to check for unauthorised vehicles. Here are three ways parking management can be made more efficient by using Dahua’s ANPR 2.0 as an example.
The ANPR function is an integral feature of the Dahua ANPR 2.0. The recommended Wizmind cameras that support ANPR are the 4MP IR bullet Wizmind network cameras and the 8MP IR bullet Wizmind network cameras. These cameras offer accurate recognition of number plate information for more than 87 countries and other vehicle attributes in the scene, and are specified with a detection rate of up to 99% and recognition rate of up to 95%. Aside from ANPR, these devices also offer other AI functions including Video Metadata, and IVS.
In addition, ANPR cameras also support block lists and allow list functions to ensure security in the monitored scene. It allows access to those in the allow list and sends an alarm when a block listed vehicle plate number has been detected. Additionally, it also features VIP Recognition that can be used in company offices and residential areas to provide smooth access for VIP customers and residents.
The Dahua ANPR 2.0 also features a Parking Space Management function. It gives operators the ability to capture data of vehicles entering and exiting the car park and display the number of available parking spaces in real time via LED screens. The system can track how many cars are parked in a given zone (up to 80 parking spaces can be covered per camera depending on different heights) and can analyse how many cars are usually in that zone at a particular time. Users can even monitor multiple car parks with one DSS system.
For drivers, the ANPR 2.0 camera controls the access to the parking facility when integrated with a barrier gate, enabling a touchless and “ticket-less” passage of vehicles and avoiding possible car congestion.
The Dahua ANPR 2.0 cameras are designed for ease of installation and have multiple mounting options. And the system supports multiple backends – it can stand alone with an SD card, or can be used with an NVR or DSS product – enabling users to leverage existing equipment. Also, only the first device needs access to wire and a power cord, other connected devices can be powered by Ethernet cables.
