HIK.ANPR.Cam.NetCore 1.0.5

HIK ANPR CAM for Modern .NET

HIK ANPR CAM is a commercial WinForms component for Hikvision ANPR/LPR cameras. It helps C# and VB.NET developers receive real-time automatic license plate recognition events, plate data, and saved vehicle images without writing low-level camera integration code.

Use it to build parking systems, gate automation, vehicle access control, traffic monitoring, and license plate recognition applications.

Supported Applications

• Modern .NET Windows applications
• Windows Forms applications
• C# or VB.NET
• x86 or x64 build platform

Install

Install the package from NuGet:

dotnet add package HIK.ANPR.Cam.NetCore

Then open the Visual Studio Toolbox and add ANPR_CAM to your form, or create it in code.

Build

1. Open your project in Visual Studio.
2. Open Build > Configuration Manager.
3. Select x86 or x64.
4. Build the project.
5. Run the application.

Do not build as Any CPU. Select the platform that matches the application you want to deploy.

Command-line build example:

dotnet build -c Release -p:PlatformTarget=x64

Use x86 instead of x64 when building a 32-bit application.

Quick Start

using System;
using System.IO;
using System.Windows.Forms;
using HIK_ANPR;

public partial class Form1 : Form
{
    private ANPR_CAM _camera;

    private void connectButton_Click(object sender, EventArgs e)
    {
        Directory.CreateDirectory(@"C:\anpr_data");

        _camera = new ANPR_CAM
        {
            CamIp = "192.168.1.64",
            CamPort = 8000,
            CamUsername = "admin",
            CamPassword = "your-password",
            PictureFolder = @"C:\anpr_data\"
        };

        _camera.NP_detected += Camera_NP_detected;
        _camera.ErrorOccurred += Camera_ErrorOccurred;

        if (!_camera.Login())
        {
            MessageBox.Show("Camera login failed.");
        }
    }

    private void Camera_NP_detected(object sender, NP_Info e)
    {
        string message =
            $"Plate: {e.StringPlateLicense}\n" +
            $"Category: {e.StringPlateCatogry}\n" +
            $"Time: {e.StrTime}\n" +
            $"Plate image: {e.PlatePicPath}";

        MessageBox.Show(message);
    }

    private void Camera_ErrorOccurred(object sender, string message)
    {
        MessageBox.Show(message, "ANPR Error");
    }
}

Important Functions

Camera Properties

Data Returned By NP_detected

The NP_detected event returns an NP_Info object.

Capture A Manual Picture

bool saved = _camera.Take_Picture("manual_capture_001");

if (saved)
{
    MessageBox.Show("Picture saved.");
}

The image is saved in the folder set by PictureFolder.

VB.NET Event Example

Private Sub AnpR_CAM1_NP_detected(sender As Object, e As HIK_ANPR.NP_Info) Handles AnpR_CAM1.NP_detected
    MessageBox.Show("Plate: " & e.StringPlateLicense & Environment.NewLine &
                    "Category: " & e.StringPlateCatogry & Environment.NewLine &
                    "Time: " & e.StrTime)
End Sub

Activation

When activation is required, call:

ANPR_CAM.ShowActivationBox();

Or apply a license code in code:

ANPR_CAM.SetLicenseCode("YOUR-LICENSE-CODE");
