Server Side Software Architecture

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

  • Linux
✎
The application is designed to run on the latest Ubuntu Linux LTS (Server Edition).
  • Nginx
  • MySQL
  • PHP


⇧ Back to Top

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 MariaDB

Media Server

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


⇧ Back to Top

Logical Server Architecture


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
  • MariaDB 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


⇧ Back to Top

Deployment Models


Network Architecture-One Server.webp

Single Server

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

Network Architecture-Multi Server.webp

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.
