PTZ cameras
Marshall PTZ camera automation for radio studios
Marshall's CV cameras are small enough for a radio desk, and VRA puts them to work in the show. It recalls an angle over VISCA over IP or NDI when a presenter starts talking, and frames the camera while it is off air.
What VRA does with Marshall.
VISCA over IP or NDI
Most CV models get VISCA over IP on port 52381. The NDI models, like the CV630-ND3, the CV730-NDI and the NDI|HB CV730-BHN, are set to NDI control.
A shot size to hold, not a person to chase
Marshall's CV612, CV620 and CV625 tracking models follow a person on their own. Camera Assist holds the shot size and face count you set per angle after calibration, and corrects the camera while it is off air.
The same angle from a mic or a button
An angle stores a camera position and the command that takes it to air. An Audio Manager trigger, a macro or a dashboard button all run the same angle.
The next shot is framed off air
After calibration, Camera Assist frames a camera that is not on air to the shot size and face count you set per angle, from close up to wide. When the switcher takes it, the picture is already right.
The USB CV605 is not controlled
The CV605-U3 and CV605-U3W are listed with USB (UVC) control, which VRA does not map. Camera Assist cannot move them.
How to set it up.
Requirements
- Camera Assist running on the same network as the camera.
- The camera's IP address, plus its username and password if it uses them.
- A preview source if you want pictures in VRA Cloud.
- A video switcher connected to VRA. Camera Assist moves and frames the camera; the switcher makes the cut.
Install Camera Assist on a machine in the studio network.
On the Cameras page, choose Add new camera, then PTZ camera, and pick your Marshall model from the list. The model fills in the protocol, the port and the lens data.
Enter the camera's host and, if it asks for them, a username and password. Add a preview: an NDI source, a stream URL or, where the model has one, the camera's own stream.
Set the PGM trigger, the switcher command that takes this camera to air. Save, and check that Camera Assist reports the camera as connected.
Build angles from preset slots or captured positions. Run calibration before you switch on AI framing.
Marshall questions
Do Marshall's NDI|HB cameras work with VRA? +
The CV730-BHN and CV730-WHN are in the model list and are set to NDI control, like Marshall's other NDI models. Test movement and the preview before you build angles.
Is my Marshall model supported? +
Look for it in the model list when you add a camera. The entry sets the protocol and lens data, and badges show which models have PTZ and NDI. If yours is missing, send us the model and firmware before you fall back on a generic profile.
Does VRA replace my video switcher? +
No. Camera Assist moves and frames the camera. The angle's PGM trigger tells your switcher to take it to air, so the switcher still makes the cut.
Can I mix in a fixed camera? +
Yes. A fixed camera gets a preview and a PGM trigger, so it can go on air like the others. It has no movement and no AI framing.

BirdDog
BirdDog PTZ cameras run on NDI, and VRA automates them over NDI too. Eyes, P and X series cameras recall their angles when a presenter starts talking.
PTZOptics
PTZOptics Move, Studio and NDI cameras speak VISCA over IP or NDI, by model. VRA automates each one over its own protocol and frames the next shot off air.
NewTek
NewTek NDI|HX PTZ cameras, from the 2017 PTZ1 to the PTZ3 UHD, run on NDI. VRA automates them over NDI and frames each shot while the camera is off air.
