D&R CamCon

Visual Radio Trigger Unit

The D&R CamCon trigger unit and its software make it possible to create Visual Radio during your live broadcast. The combination of the Camcon, its application software, VRC software and OBS is all you need. CamCon measures microphone levels and sends these over an USB link to a PC where visual radio software runs.

The CamCon is very simple to use. The unit is placed in series with the microphone and the mixing console without any interference with the Mic signal. 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 level measurement to switch camera's can be done on the front panel with one single push switch.

The 4 channel Camcon trigger unit can be connected (hardwired) in series with up to 4 microphones to control our VRC software that can switch scenes in OBS (freeware). In this way Visual Radio can be streamed over the Internet together with your audio. This is the perfect way to make your station visible to the listener.

By using the Camcon unit, it is possible to trigger/switch scenes automatically, depending on who is talking.

The Camcon application software measures microphone levels and sends these over an USB link to your PC where Visual Radio Control software runs.

OBS (freeware) uses real audio devices connected as triggers. The Triggerbox / Camcon is very simple to use.

The Visual Radio Control (VRC software) connects the scenes from the Broadcasting Software to channels on the Camcon Visual Radio device.

With metering and the MicOn information that the Camcon provides to the Visual Radio Control (VRC) software it is possible to make decisions which scene needs to be active at a given moment. Settings like Priority, Hold time and Activation delay can be set to suit your needs.

The gain for the level measurement 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. All XLR Mic inputs are hardwired to their corresponding XLR outputs.

​The inputs and outputs are 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.

The USB connector needs to be wired to the PC. GPI and GPO have various extra possibilities to control signals or receive trigger info per microphone.

The Camcon needs to be used with the Camcon Control (CCS) Software and Visual Radio Control (VRC) software.

Both software packages can be downloaded from D&R website when installing the CamCom hardware.

This VRC software will process the Camcon data to control the camera’s connected to OBS (free open source software)

The final signal flow will be: MIC > CAMCON > VRC > OBS.

The Camcon can add 4 Camera’s to any mixing console.

It’s possible to let the Camcon Unit work with all D&R mixers or any other mixing console!

The VRC software will process the CamCon data to control OBS (free open source software)

The D&R CamCon Trigger Unit needs the following software:

• CamCON server software (included)
• Visual Radio Control (VRC) (included)
• OBS (freeware)
