VaxALPR On Camera

License plate recognition technology embedded in AXIS camera

VaxALPR On Camera is the result of VaxOCR Engine full porting technology into AXIS camera.
After a complete OCR engine redesign we’ve accomplished the task of embedding the same analytics existent in higher-end processor architectures such as Intel, among others.


Thus, the only existent constraint is defined by the speed of the vehicles, not the scenario complexity. For those scenarios suitable to use VaxALPR On Camera, the accuracy results will be the same.


VaxALPR On Camera is available for all AXIS models housing ARTPEC-4, ARTPEC-5 and ARTPEC-6 chips. The OCR configuration takes place through the standard camera menu accessible from a Web browser.

Brief overview of the product capabilities

  • Triggered mode: The ANPR attempts to read the plate after receiving a signal or event from the camera input port. This is very useful for parking or scenarios ruled by loops, laser curtains, etc
  • Free-Flow mode: The ANPR works in continuous mode and does not require any trigger to operate. All plates read are reported in real time
  • Hot lists: Basic white/black lists embedded inside the camera, web management, csv import and API available to manage from third party software
  • Instant Speed Plugin: Calculate the vehicles instant velocity in slow and medium speed environments (Artpec-6 only)
  • ADR Plugin: Read conventional and dangerous good plates simultaneously

Results integration

  • Vaxtor open proprietary format through standard TCP/IP sockets. The message format is detailed in the user manual. We have available a class library in .NET to easily parse raw data results and access the information through object class members.
  • AXIS A1001 Network Door Controller
  • AXIS Camera Station (ACS)
  • Vapix / Onvif
  • XML formatted data through post (http) including Milestone Analytic Events
  • SD card or Shared Network Unit
  • Embedded SQL Lite Database

AXIS camera type, scenarios and limitations

ARTPEC-4 and 5

Suitable for parking environment with stopped vehicles. Depending on the video resolution, analyics complexity level and the size of the detection polygon defined by the user, the OCR recognition time may take up to 4 seconds with Artpec-4 processors and up to 2 seconds with Artpec-5. These metrics are just indicative. 

If you need to use VaxALPR On Camera in scenarios with vehicles in motion we strongly recommend to use a camera with Artpec-6 or 7 processor.

ARTPEC-6 and 7

Suitable for any ARTPEC-4 and 5 environment plus medium or high speed scenarios up to 160 Km/h one lane frontal reading. To manage 2 lanes or angled scenarios the maximum reading speed is around 100 Km/h. Depending on the video resolution, scenario difficulty and the analytics complexity the recognition time may vary considerably.

These metrics are indicative and valid for those countries where the license plate characters are equal in height and have the same fron/back color pattern. In countries such as Singapore, Malaysia, United Arabi Emirates, USA… these limits may change.
