What Is QR Code Setup in gCMOB?

QR code setup is a device-adding method that allows users to scan a code linked with a supported CCTV device. After scanning, gCMOB can read device information and help the user add the camera system to the app.

This feature is helpful for users who do not want to manually type device details.

QR setup is useful because it can:

• Save time
• Reduce typing mistakes
• Help beginners
• Make device adding easier
• Avoid wrong serial number entry
• Speed up mobile setup
• Improve connection accuracy

Why Use QR Code to Add Cameras?

Manual device setup can be confusing for new users. A DVR, NVR, or IP camera may require serial number, IP address, port, username, password, and device type. QR code setup can reduce this work.

It is one of the simplest ways to start using gCMOB.

QR code setup is useful for:

• Home CCTV users
• Shop owners
• Office users
• Beginners
• CP Plus device users
• Multi-camera setups
• Fast device adding
• Remote viewing setup
