A Windows application that integrates vMix video production software with Canon PTZ cameras to provide automated tally light control. When an input becomes active in vMix, the corresponding camera's tally light automatically turns on, providing clear visual feedback to camera operators.
Meant for Canon PTZ Cameras like CR-N300, CR-N500, CR-N700.
- Real-time Tally Control: Automatically controls Canon PTZ camera tally lights based on vMix active inputs
- vMix Integration: Connects to vMix TCP API for live tally status updates
- Multiple Camera Support: Manage and control multiple Canon PTZ cameras simultaneously
- Visual Feedback: Real-time connection status and tally state indication in the UI
- System Tray Integration: Minimize to system tray for unobtrusive operation during production
- Camera Testing: Built-in connection testing for both vMix and individual cameras
- Settings Management: Save and load camera configurations with recent files support
- Automatic Reconnection: Auto-retry connection to vMix if connection is lost
- Authentication Support: Optional HTTP Basic Authentication for camera control
- Operating System: Windows (Windows 10 or later recommended)
- Runtime: .NET 8.0 Runtime
- vMix: vMix software running with TCP API enabled (default port 8099)
- Cameras: Canon PTZ cameras with HTTP API support
- Download the latest installer from the Releases page
- Run the installer and follow the setup wizard
- Launch the application from the Start Menu or desktop shortcut
-
Configure vMix Connection

127.0.0.1) - Enter vMix TCP port (default:
8099) - Click "Test Connection" to verify connectivity
- Enter your vMix IP address (default:
-
Add Cameras
- Enter camera details in the grid:
- Camera Number: Corresponding vMix input number (1-based)
- IP Address: Camera's network IP address
- Username/Password: Optional authentication credentials
- Enter camera details in the grid:
-
Start Tally System
- Click "Start" to begin monitoring vMix and controlling tally lights
- Camera tally lights will automatically respond to vMix input changes!
-
Save Configuration
- Use File > Save or Save As to save your camera configuration
- The application will automatically reload your last configuration on startup
vMix → TCP Connection → Application → HTTP API → Canon PTZ Cameras
- vMix TCP Connection: The application subscribes to vMix's TALLY events via TCP API
- Tally Processing: Parses tally status strings to identify active (program) inputs
- Camera Control: Sends HTTP commands to Canon cameras to turn tally lights on/off
- Program (On-Air): Red tally light
- Off: Tally light turns off
Each camera is mapped to a vMix input number:
- Camera Number
1= vMix Input 1 - Camera Number
2= vMix Input 2 - And so on...
When a vMix input becomes active (program), the corresponding camera's tally light turns red.
Configuration files are stored as XML and contain:
- vMix connection settings (IP address and port)
- Camera configurations (number, IP, credentials)
The application uses Canon's HTTP control API:
- Endpoint:
http://{camera-ip}/-wvhttp-01-/control.cgi - Tally ON:
?tally=on&tally.mode=program - Tally OFF:
?tally=off - Authentication: HTTP Basic Authentication (optional)
- Visual Studio 2022 or later
- .NET 8.0 SDK
- Verify vMix is running and TCP API is enabled
- Check that the IP address and port are correct (default:
127.0.0.1:8099) - Ensure no firewall is blocking the connection
- Use "Test Connection" button to diagnose
- Verify camera IP addresses are correct and cameras are on the network
- Test camera HTTP API access from a web browser:
http://{camera-ip}/-wvhttp-01-/control.cgi?tally=off - Check if authentication is required and credentials are correct
- Ensure cameras are Canon PTZ models with HTTP API support
- Verify the camera number matches the vMix input number
- Check that the vMix input is actually in program (not preview)
- Ensure the tally system is started (status shows "Running")
- Review the status messages in the application for errors
