1.1. SDK architecture

1.1.1. Introduction

Camera SDK is based on the Tuya Smart SDK and encapsulates the functions of smart cameras. The entire SDK architecture is divided into three levels: Tuya Smart SDK, IPC network communication layer, and camera business layer.

- **Tuya  Smart  SDK**  provides a home-based package for hardware devices and Tuya cloud communication.
- IPC network communication layer provides P2P network channel implementation.
- The camera business layer provides audio and video communication and display, equipment function points, alarm messages, cloud storage video management and other business functions.

1.1.3. Component module

The module consists of a view module, a middleware module, a message center module, a device signaling module, a P2P communication module, and a basic tool library module.

• The view module is mainly camera-related UI components, such as video player display controls.
• The middleware module provides interface functions that isolate services from the SDK.
• The message center module provides the alarm message function of the IPC equipment required by the service.
• The device signaling module provides Mqtt-based device control signaling data transmission and reception functions.
• IOTCamera module provides IP Camera P2P function and audio and video data transmission and reception functions.
• Auxiliary function module provides a series of auxiliary functions.
