News & Events at DigiBox

Offering exceptional HD or UHD picture quality, 20-30x optical zoom, great low-light performance, and phantom-powered audio, the PTZ3 PLUS and PTZ3 UHD PLUS cameras combine quality hardware with intelligent production-enhancing features, including AI presenter tracking and the world’s first FreeD tracking data embedded via NDI|HX. All in a sleek, discrete body that blends into any space.


Vizrt PTZ3 Plus camera range

Whether you’re live streaming, producing a corporate town hall, capturing live events, or anything else that demands high quality audio and video, PTZ3 PLUS cameras have you covered. NDI connectivity means the camera simply appears on your network for easy setup, and configuration of augmented reality/virtual reality solutions like Viz Virtual Studio Go is now easier than ever with FreeD tracking data embedded in every frame over NDI|HX. You’ll be making broadcast-quality productions in no time!


Cover all bases with NDI® at its core, 3G-SDI and HDMI outputs, and RS232 control. Simplify setups with a single ethernet cable providing NDI® audio and video plus PTZ control, tally, power, and the world’s first FreeD-over-NDI|HX.

Vizrt PTZ cameras simply appear on the network and can immediately be built into any workflow with ease, while native NDI®|HX3 compatibility delivers broadcast quality video with super low latency – using a fraction of the bandwidth of full NDI.

Combined with Viz Connect Tetra’s NDI Bridge functionality, PTZ3 PLUS cameras can be deployed anywhere in the world and automatically connect to your network for the simplest remote setups.







Capture presentations and live productions in crystal clear clarity with HD or UHD 4K resolutions, with wide aperture lenses, large sensors, and optical low pass filters giving excellent low light performance and depth of field control.

Intelligently track presenters automatically with AI presenter tracking, so talent is always in shot and exactly where you want them to be, with multiple subject framing choices and aspect ratios to choose from.

Connect to any powered and non-powered audio source with phantom-powered mini XLR input for professional audio capture with microphones, mixers, amplifiers, and soundboards.



Create content easily by connecting and controlling your PTZ3 PLUS camera to any TriCaster, CaptureCast, Viz Virtual Studio Go, or any other SDI- or NDI-enabled device.

Adjust subject tracking using macros on your TriCaster, while silky smooth ease-in and ease-out movements deliver seamless, smooth transitions for a natural, superior-quality production without jittery or stuttering movements.

Create exciting audience experiences with easier than ever setup of AR/VR systems like Viz Virtual Studio Go with embedded FreeD camera tracking data over NDI|HX.


AI presenter tracking

PTZ cameras are found in more places than ever, but often without dedicated camera operators, or inexperienced operators. Integrated presenter tracking AI removes the headaches of camera setup and manual tracking, to ensure talent is always in shot. Simply use the software UI’s “Tracking” tab to easily fine-tune your tracking options, including:

Initial face detection

Intelligently tracks presenters even when they face away from the camera; for example, if they’re presenting from a virtual or physical screen and turn to face it.

Presenter memory and tracked target switching

Presenter memory ensures the camera won’t switch even if someone else enters the frame – unless you want it to, with tracked target switching making it easy to switch between presenters. Choose from switching left, right, or to first tracked.

Blackboard detection

Intelligent blackboard detection identifies if the presenter has entered a “presentation area”, e.g. with a whiteboard/blackboard, and will lock in place as the presenter moves around it for a more enjoyable viewer experience.

Adjustable framing ratios

Perfectly frame your talent by choosing from six framing ratios; 1/6 up to 1/20 ratios.

Subject framing

Choose whether your presenter is framed to the left, centre, or right of the frame.

Tracking limit windows

Keep the camera within a set range by setting a tracking limit window with top left and bottom right frames. This helps ensure the camera doesn’t track off-set or break a green screen effect.

Home position time out

Decide when the camera stops attempting to track a presenter after they leave the range of the PTZ3 PLUS camera or your set tracking window and return to a default home position. Choose from 0.5 to 10 seconds timeout, after which the next presenter to enter the frame becomes the next tracked presenter; ideal for lecture, meeting, and event capture.


FreeD is a commonly used protocol that sends the axis of camera movement – position (X, Y, Z axis), rotation (pan, tilt, roll), and lens data (focus and zoom) through UDP packets over a network. It is often used to integrate AR graphics into live broadcasts, such as Viz Virtual Studio, and usually requires its own cable to transmit this information, making camera setup with XR/AR systems more complex. With the PTZ3 PLUS and UHD PLUS, FreeD open-source metadata is embedded in every frame within NDI|HX, radically simplifying the setup of solutions like Viz Virtual Studio Go out of the box. Combined with pre-configured lens files, broadcast-quality AR/VR graphics are now within reach of every content creator.

Professional phantom-powered mini XLR audio

Use the phantom-powered Mini XLR connection in addition to the standard line-in. Delivering clean, professional-level audio directly from the camera into the NDI network, the mini XLR feature offers an array of connectivity options. When combined with NDI Audio Direct, the XLR audio connects to NDI receivers and virtually any audio software providing unprecedented levels of creative flexibility.

Phantom power delivers +48v to powered microphones and requires a two-step confirmation in the UI to avoid accidentally sending power to non-powered mics.

Multicast Mode

Optionally allow multiple destinations to receive video from your NDI®|HX PTZ Camera without individual point-to-point connections to conserve network bandwidth.

NDI® Output

Acquire and deliver video to the network in full UHD or HD, with NDI® output via NDI® and native support for resolutions up to 2160p or 1080p at 60 frames per second.


Enjoy advanced flexibility and simplicity: using an NDI®|HX enabled device, users can select NDI®|HX 3 as an option for better video with reduced latency – using a fraction of the bandwidth – all while maintaining the visually lossless standards NDI users’ demand.

Power over Ethernet (PoE)

Streamline installation and reduce cabling complexity, optionally eliminating the need for a separate power supply connection with support for Power over Ethernet via POE+.

Pan-Tilt-Zoom (PTZ)

Perform real-time pan, tilt, and zoom camera movements with motor-driven PTZ camera control and configurable preset positions. Silky smooth ease-in and ease-out movements offer natural movements.

3G-SDI and HDMI output

Optionally acquire and deliver video into conventional workflows with support for 3G-SDI and HDMI hardware output.

Program and Preview Tally

Receive tally notification from compatible NDI® devices via physical LEDs when video output from your NDI®|HX PTZ Camera is visible on Program and/or Preview.

Remote Control & Monitoring

Operate camera controls, monitor video, manage login credentials, and configure audio, video, and network settings from any compatible networked device using the Web-based user interface or NDI® Studio Monitor.

Remote Recording

Capture live PTZ Camera video remotely from any compatible computer or device using NDI® Studio Monitor.

Video Settings

Manage PTZ Camera options to include exposure, focus, iris, shutter speed, white balance, wide dynamic range, and more with configurable video settings.


Present high-quality audio, with support for mic and line level audio input, and adjustable volume control.

NDI® Webcam Input

Designate your Vizrt PTZ Camera as the video input source in popular desktop video applications like Google Hangouts, GoToMeeting, Skype, Skype for Business, WebEx, Zoom, and more, via the included software driver.

Network Identification

Easily identify your Vizrt PTZ Camera on the network with the ability to apply custom device and channel names. NDI® offers auto-discovery; all connected NDI devices are able to find each other automatically without the need to enter IP addresses and port information.
