How to quickly master the technical key points of secondary development of Java Hikvision SDK

Abstract: In recent years, Hikvision’s monitoring equipment has been widely used in various industries , in order to better meet the needs of different scenarios, Hikvision provides a powerful SDK for developers to carry out secondary development. This article will introduce how to quickly master the technical points of secondary development of Java Hikvision SDK and provide some code examples.

1. Understand the basic architecture of Hikvision SDK

Before starting secondary development, we must first understand the basic architecture of Hikvision SDK. Hikvision SDK is mainly divided into three layers: platform layer, underlying API layer and application layer.

1. Platform layer: The platform layer is the core of the entire SDK, providing infrastructure and general functions, including system initialization, device login, real-time preview, video playback, device configuration, etc.
2. Underlying API layer: The underlying API layer is responsible for communicating with specific devices, including network layer, transport layer, protocol layer, etc. Developers usually do not need to call the underlying API directly.
3. Application layer: The application layer is the top layer for developers to interact with devices. Developers can customize development according to their needs, such as data interaction with devices, video image processing, etc.

2. Configure the development environment

Before starting secondary development, we need to configure the development environment first.

1. Install Java development tools (IDE): It is recommended to use common Java development tools such as Eclipse and IntelliJ IDEA.
2. Download Hikvision SDK: Download the latest version of Java SDK on the Hikvision official website.
3. Import SDK library: Import the relevant library files in the SDK into the development environment.

3. Log in to the device to obtain real-time preview

Below we will use a simple example to demonstrate how to use Hikvision SDK for real-time preview.

1. Create SDK initialization object

HCISDK sdk = new HCISDK(); sdk.init();

2. Log in to the device

HCDevice device = sdk.login("192.168.1.100", "admin", "123456");

3. Start real-time preview

HCRealtimePreview preview = device.createRealtimePreview(1); preview.start();

4. Video playback

Hikvision SDK also provides the video playback function. Let’s demonstrate how to perform video playback.

1. Create playback object

HCPlayback playback = device.createPlayback();

2. Set playback parameters

playback.setStartTime(new Date()); playback.setEndTime(new Date()); playback.setChannel(1);

3. Start playback

playback.start();

5. Device Configuration

Haikang SDK provides powerful device configuration functions, and developers can implement customized device configuration through secondary development.

1. Create device configuration object

HCDeviceConfig config = device.createDeviceConfig();

2. Set device configuration parameters

config.setParam("key", "value");

3. Apply configuration

config.apply();

6. Summary

This article introduces how to quickly master the technical points of secondary development of Java Hikvision SDK, and provides some code examples. Through learning and practice, developers can better master the development technology of Hikvision SDK and flexibly apply it in various scenarios. At the same time, you also need to practice and explore more to continuously improve your development capabilities. I hope this article will be helpful to understand the introduction and technical points of Java Hikvision SDK.
