Server Side Software Architecture

Our server-side software is built on a standard LEMP stack consisting of:

• Linux
• Nginx
• MySQL
• PHP

✎

The application is designed to run on the latest Ubuntu Linux LTS (Server Edition).

Core Application Components

Web Server

• Serves the PHP-based application and user interface
• Powered by the Nginx web server

---

Database

• Stores all unique, customer-specific configuration and application data
• Implemented using MySQL

---

Media Server

• Manages communication with cameras
• Handles video streaming to client PCs
• Responsible for recording, storage, and clip creation

Logical Server Architecture

From a networking and service perspective, the application is divided into two main server roles: Application Server: The Application Server hosts the core application logic and includes:

• PHP web pages served via Nginx
• MySQL database services
• Node.js messaging and control service

---

Media Server: The Media Server is responsible for all video-related operations, including:

• Camera communication
• Video stream distribution to clients
• Recording management and clip generation

Deployment Models

Single Server

The entire server-side software stack can be deployed on a single physical or virtual server. This configuration is suitable for smaller installations and environments with lower camera counts.

---

Multi-Server

For larger deployments—such as those exceeding 50 cameras or spanning multiple departments—the system supports a distributed architecture using multiple Media Servers.

In this model:

• One Application Server hosts the core application services
• One or more dedicated Media Servers handle video processing and storage
• Media Servers can be added incrementally to scale performance and capacity

🕮

This architecture provides flexibility, scalability, and efficient handling of high video workloads.
