What is CAMCON?
The "CAMCON (CAMera CONtrol Triggerbox)" measures microphone levels and sends these over a USB link to a PC where visual radio software runs.
The Triggerbox/CAMCON is very simple to use. The unit is placed in series with the microphone and the mixing console. Therefore each channel will have an XLR input and an XLR output that also acts as a thru connector. In order to support multiple microphones, the gain for the level measurement to switch camera's can be done on the front panel with one single push switch. NOTE: This has no influence on the Mic XLR signal and is only for internal measurement.
This product needs to be used with the following software: CAMCON server software (included), Visual Radio Control (VRC) (included) and OBS (freeware version 27 only).
Wiring Diagrams
Wiring diagram for AIRLITE mixer: This diagram illustrates the connection of the CAMCON unit between a microphone, the AIRLITE mixer (showing MIC IN, GPI, GPO ports), and a PC running OBS. It visually represents how audio signals and control data flow through the system.
Wiring diagram for AIRERNCE mixer: Similar to the AIRLITE diagram, this shows the CAMCON unit's integration with an AIRERNCE mixer, connecting microphones, the mixer's inputs/outputs, and the PC running OBS for visual radio control.
Connections and Front Panel
The CAMCON requires a power source between 100 and 240 volt AC. The included USB cable connects the CAMCON to your PC, where the software operates. Microphone cables are hardwired, connecting in and out of the unit. The GPI and GPO jacks are wired on tip and ring, supporting both mono and stereo cables.
On the front panel, you can adjust the incoming Mic level using pushbuttons, which can also be done via the software. LEDs indicate the level settings and signal presence. If GPI or GPO is active, corresponding LEDs will illuminate. The Status LEDs on the right side of the front panel indicate if the unit is powered on and if the USB connection is active.
Software Installation and Setup
Necessary Downloads
Before installing the Visual Radio Control (VRC) software, it is crucial to install the Camcom application software first, followed by the OBS freeware. Only then can the VRC software establish links to both applications.
Installing CAMCON Software
1. Go to the www.dnrbroadcast.com website. 2. Click on the tab "Your Support", then choose the tab "Service information / FAQ". 3. The D&R WIKI page will be displayed. Select the Camcon device to navigate to its product page. 4. Choose "CamCon Control" to start your download. You may encounter pop-up screens warning about malware; these can typically be ignored. If malware protection alerts appear, select "more info" and choose to accept/continue.
Installing OBS Studio
OBS Studio version 27 is required for compatibility with the D&R VRC software (version 28 is not yet supported). Download links are provided:
Installing OBS Websocket Plugin
The Visual Radio Control software requires the Websockets Plugin for OBS Studio to be controlled by other software.
Download the OBS Studio Websocket Plugin from: OBS Project Forum. On the page, click "Go to download", scroll to the bottom, and download the plugin for your system. Install it according to the included instructions. Note: Version 1.0.0 supports Websocket Protocol version 4.X.
Configuring the Websocket Plugin
After installing and restarting OBS Studio, the plugin will appear in the "Tools" menu. Click "Tools" > "Websockets Server Settings". Ensure "Enable WebSockets server" is checked. You can optionally set a password for access control, which must also be configured in the VRC settings.
Installing Visual Radio Control (VRC)
Download VRC from the D&R website (www.dnrbroadcast.com) via the "Your Support" > "Service information / FAQ" section, selecting the Camcon device on the D&R WIKI page.
Installation options include:
- Choose "Install for all users" (recommended).
- Select Destination Location.
- Select additional Tasks.
- Create a desktop shortcut.
- Click "Install" and then "Finish".
Upon successful installation, the VRC software will display a start screen indicating that no scenes are available yet, requiring setup in the broadcasting software.
Using the System
Initial Configuration
To check if the current configuration is working, start Visual Radio Control. Ensure CAMCON CONTROL and OBS Studio 27 (with the plugin) are running. Click the 'Cogwheel' icon labelled 'Configuration'.
The configuration screen displays connections: VRC engine connection, CamCon hardware connection, and OBS Studio Websockets Server connection. A green 'check-mark' ✔️ indicates a live connection. If not, refresh connections by pressing F5 or consult the "Trouble Shooting Section".
Accessing the Interface
After installation, you can access the system via your web browser at http://localhost:8519/. A blank screen indicates no Camcon connection. Refreshing the screen (F5) or restarting the Camcon application may resolve this. The 'ON' LED (below 'STATUS') should be green when the Camcon Device is connected and turned on.
Renaming Channels
To make channels easily recognizable, you can rename them. Double-click or right-click a channel name and select "Change channel name" from the menu. Enter the new name in the dialog box and click 'Ok'.
Channel Settings
By right-clicking on a label, you can access various settings:
- Gain: Adjust levels (0|20|30|50dB), also controllable from the front panel.
- GPI triggers: Options include "None" or "Mic on".
- GPO triggers: Options include "None", "GPI", "Mic on", "Remote".
- Identify channel: This action causes the CamCon LEDs on the hardware to blink, helping to identify specific channels.
Identifying Devices/Channels
To confirm device connection or distinguish between multiple Camcon Devices:
- Click the 'Camcon' word on screen.
- Click the 'D&R' logo.
- Right-click on the left side of the device and select 'Identify' from the menu.
Performing any of these actions should cause the connected Camcon Device's 'Gain' LEDs to blink. If no response occurs, the PC-to-Camcon connection has failed. You can also identify individual channels by clicking their separator bar or right-clicking and selecting 'Identify channel'.
Creating and Managing Scenes
In the VRC software, hit the "+ Add scene" button. The scene menu allows you to connect scenes from your broadcasting software (like OBS) to audio sources. The VTR software then activates a scene when a corresponding audio source becomes active.
Scene Properties:
- Scene Name: Retrieved automatically from VRC software, should match OBS scenes.
- Audio (metering) source: Select an OBS scene. This provides metering information to decide if a channel (e.g., someone speaking) should activate its scene. Metering information is not the sole factor; the 'MicOn source' must also be active.
- MicOn source: Select an OBS source to control the scene. Typically, this is a mixer channel turned 'On' with its fader not at minus infinity. For Camcon, this can be the 'GPI' signal. The 'MicOn source' must be active for the 'Audio source' to be monitored.
- Metering threshold: Sets the minimum level (-50dB to +5dB) required for activation. 'Gain' settings affect the measured level.
- Scheduling priority: Determines focus when multiple sources are active. Higher values increase priority. Range: -999999 to +999999.
- Hold time: (0-10 Sec) Keeps a scene active for a set duration to prevent flickering, even if the audio level drops or 'Mic on' deactivates.
- Activation delay: A delay before a scene becomes active, useful for handling background noise or brief audio events.
Modifying and Removing Scenes: Click the 'Edit scenes' button to modify scene properties. To change a scene for sources, you may need to remove and recreate the scene. A 'Delete' button is available under each configured scene for removal.
Direct Control: After configuration, click 'Edit scenes'. All configured scenes are then controlled by the 'engine' and will automatically activate in the broadcasting software.
A setup with 4 cameras might look like this:

Good to Know, Tips, and Hints
- The Visual Radio Control engine operates in the background without needing a browser to be open.
- The engine directs your broadcasting software as long as configured scenes are available.
- The engine connects to and updates the browser UI when open.
- You can monitor and influence the engine via the browser.
- Scenes can be activated manually by clicking them. The currently focused scene has a distinct indicator.
- Closing the web browser does NOT stop the engine. The engine must be stopped separately.
- For multi-PC setups, ensure correct hostnames or IP addresses are entered and click 'Apply'. A green checkbox ✔️ indicates a successful connection.
- On a single PC, a green 'check-mark' ✔️ indicates a live connection. Use F5 to refresh connections.
- When accessing from another PC or mobile device, if you see a yellow-ish arrow figure, it means no active connection. Change the URL from
ws://127.0.0.1:10840
tows://<ip-address-of-pc>:10840
and click 'Apply'. - Connection information is viewed from the engine's perspective. 'localhost' refers to the local PC.
Scene Properties Explained
Scene Name: Retrieved from VRC software, should match OBS scenes. Assign 'Audio source' and 'MicOn source' for proper control.
Audio Source: Provides metering information for the VRC software to determine channel activity and scene activation. 'MicOn source' must be active before metering is monitored.
MicOn Source: Typically a mixer channel that is 'On' with its fader not at minus infinity. For Camcon, this can be the 'GPI' signal connected to the GPI input port. The 'MicOn source' must be active for the 'Audio source' to be monitored and considered for scene activation.
NOTE: If your mixer lacks a GPO signal, patch the GPI to the same channel's GPO and activate the GPO output in the 'Camcon Configuration Manager'. This may lead to scenes switching solely by mic signals, even if a fader is down.
Troubleshooting
- OBS Version Compatibility: D&R VRC software may not work with OBS version 28. Use version 27. Links are provided for download.
- WebSocket Plugin: Ensure the plugin is correctly installed and configured in OBS.
- USB Device Not Recognized: Refresh with F5 or unplug and replug the USB cable.
- Cannot Connect: Check your USB cable and refresh with F5.
- "Windows Defender" Reports Virus: Uninstall the software and perform a fresh installation rather than upgrading. Download from the specified link and access via http://localhost:8519/.
Ensure your Camcon Device is connected via USB to your PC and powered on. The 'ON' LED (under 'Status') should be green.
