Hikvision HikWire blog article License Plate Recognition (LPR) Technology: LPR White Paper

Hikvision’s license plate recognition (LPR) technology enhances vehicle and parking entrance control systems by improving accuracy. You can download a copy of our newest technology white paper to learn more at this link: “HIKVISION: License Plate Recognition Technology, The essential component of a sophisticated vehicle management system.”

The LPR white paper provides an in-depth explanation of how the technology works to provide a more effective license plate reading system. Engineered with the latest deep learning algorithms and GPU processors, Hikvision LPR cameras provide precise collection of vehicle and license plate data for more efficient parking entrance management and site security.

Hikvision LPR technology has these capabilities:

  • Extracts license plate data from complex backgrounds
  • Separates and recognizes each character on the license plate
  • Reformats the plate information for improved character recognition

With Hikvision LPR technology, low light areas, hard-to-see vantage points, and non-standard plate characters no longer create barriers to plate recognition.

Learn more about this technology by visiting our Vehicle Entrance Control webpage. The webpage details the Hikvision LPR solution, recommends specific Hikvision product models, and provides a link to download the LPR white paper.

IMPORTANT! Ce modèle nécessite un logiciel non standard. N'installez pas de logiciel standard (par exemple, v.4.1.xx) sur ce modèle. Cela endommagerait définitivement votre système. Vous devez utiliser le logiciel personnalisé v.4.1.25 à partir de la page du produit iDS-9632NXI-I8/16S

The I-series NVR (such as the DS-7716NI-I4) is one of Hikvision's most popular and feature-rich recorders. As such, many firmware revisions have been introduced over the years to continually ensure the product is compatible with the newest technology available. Due to the many revisions, we recommend that the user closely follows the instructions below in order to reduce the amount of time spent as well as the chance of failure.

 

Database Optimization and Repair

As more affordable IP cameras are introduced over time with greater video resolution and data sizes, more efficient database management also becomes necessary. The introduction of firmware v4.0 brought about a new database architecture in order to be futureproof.

 

After upgrading to v4.X, the recorder database will need to be converted and optimized. If you are experiencing issues where playback is expected but not found, make sure "Database Repair" is performed as indicated in the procedures and scenarios below.

 

Preparing the Upgrade

Before proceeding with upgrade, it is recommended that NVR configuration file is exported from the NVR over the network or on to a local USB drive.

 

Upgrading from v3.4.92 build 170518 or Older

  1. All recorders must reach v3.4.92 before proceeding further. Upgrading from versions before v3.4.92 directly to any version of v4.X will likely cause the recorder to fail.
  2. If the recorder is already at v3.4.92, a full factory default is highly recommended before upgrading to any version of v4.X. There is a high chance of unit failure (requiring RMA) if the unit is not defaulted before upgrade.
  3. After reaching v3.4.92 and performing a full factory default, an upgrade directly to v4.50.00 is acceptable.
  4. After the upgrade is completed and the recorder is reprogrammed, it may be beneficial to perform a Database Repair. For details, refer to the section "Database Optimization and Repair" above.
  5. To verify repair progress, you may refer to the HDD status, or search the recorder log for repair started and stopped entries. Note that while the HDD is repairing, new recordings are still being made, but some existing recordings may not be searchable until repair is complete.
  6. If you continue to observe playback issues after database repair, ensure there are no power, network, or motion detection issues. Should the problem persist, contact technical support.

 

Upgrading from Any v4.X Build to v4.50.00.

  1. Any v4.X build can be upgraded directly to v4.50.00.
  2. Export configuration is highly recommended before performing the upgrade.
  3. If upgrading from any v4.X version that was not v4.22.005, a Database Repair is recommended. Refer to Step 4 and onwards in the previous section.

 

Downgrading

Downgrading is not recommended. Due to new features and parameters constantly being added, downgrading may cause the NVR to factory default itself or require a manual default to operate properly.
