Automatic number plate recognition (ANPR; see also other names below) is a technology that uses optical character recognition on images to read vehicle registration plates to create vehicle location data. … Systems commonly use infrared lighting to allow the camera to take the picture at any time of day or night.

Improve efficiency and security while reducing costs

Automatic number-plate recognition(ANPR) is a technology that uses optical character recognition on images to read vehicle registration plates.

Rapid technological developments have allowed DaHua to enable camera-side integration of ANPR technology. This means it can be widely used to improve efficiency and security in different solutions. In addition, this camera-side ANPR is more cost-effective than traditional server-side analysis solutions.

Key Technologies

Dahua ANPR solutions include Dahua cameras and software that runs on either the camera or a server. It automatically captures license plates in real time. Relying on big image data and well train deep-learning models, the ANPR engine includes the following features:

  • Multilingual Recognition Recognizes English, Arabic, Chinese, Cyrillic, Thai, and other languages
  • High Recognition Rate – 95%-98% with alphanumeric number plates
  • Fast Recognition – The full reading process takes around 100 milliseconds
  • Cost-effective Technology – Outstanding price/performance ratio
Traffic Cameras and Security Cameras


Automatic ANPR is a valuable solution for multiple applications, including:

  • Road Safety Enforcement Automatically recognizes speeding and red-light violations
  • Law Enforcement, Verify vehicle license and registration. Provides an automatic alert when blacklisted vehicles pass by
  • Electronic Toll Collection, Enables free-flow through and catches the vehicle plate number
  • Parking Guidance, Automatically recognize available parking spots and guides vehicles along the best route
  • Entrance & Exit Control, Raise barriers for authorized vehicles
