VX720LG — 4K 60fps Broadcast-Grade AI Intelligent PTZ Camera
Product Positioning
The VX720LG is the flagship broadcast-grade PTZ camera in VHD’s 4K UHD series. It features a 1/1.55-inch 50MP CMOS sensor and a 20x optical zoom telephoto lens, supports 4K@60fps and 1080P@120fps output, and is equipped with PDAF millisecond-level focusing and in-house ReID/FaceID AI intelligent tracking. It targets high-demand scenarios such as broadcast live production, virtual production, and professional AV integration.
Core Features
Cinematic Image Quality
Equipped with a high-quality 1/1.55-inch CMOS sensor with 50MP effective pixels, it supports 4K@60fps output and is downward compatible with 1080P and 720P. It supports the HDR10 high dynamic range color standard and BT.2020 wide color gamut (color gamut range doubled compared with BT.709). 10-bit color depth displays approximately 1.07 billion colors, delivering color transitions close to human perception and reducing post-production color grading difficulty.
High-Speed Capture and Millisecond-Level Autofocus
Supports 1080P@120fps high-frame-rate video, enabling clear slow-motion playback without stuttering. Built-in PDAF phase-detection autofocus technology accurately locks onto the subject in real time—whether it is an athlete sprinting in a sports event or a singer dancing energetically on stage.
AI Intelligent Tracking
Built-in in-house ReID person re-identification and FaceID facial recognition algorithms accurately identify and focus on subjects based on facial, human-shape, posture, and clothing information. It precisely tracks target movement even in complex environments, keeping the target at the visual center of the frame.
Professional Interfaces and Protocols
The VX720LG supports simultaneous output of five channels of high-definition digital signals via HDMI, 12G-SDI, 3G-SDI, USB, and network interfaces. HDMI, 12G-SDI, and 3G-SDI can directly output uncompressed high-definition lossless video. It supports the NDI6 network transmission protocol and the free-D virtual production tracking protocol, enabling seamless integration of live-action footage with 3D virtual backgrounds.
Engineering-Friendly Design
60° wide angle + 20x optical zoom (f=6.55–126mm, F1.8–4.5), horizontal rotation ±170°, vertical -30° to +90°, 255 presets, and preset accuracy of 0.1°. The body features front and rear Tally lights with adjustable brightness and a standard filter mount for external ND and CPL filters. Supports PoE+ power. Minimum illumination 0.5 Lux, signal-to-noise ratio ≥55dB, 3D digital noise reduction.
Application Scenarios
- Broadcast studios and sports live production: multi-camera shooting for sports events, concerts, and variety shows; 120fps slow motion and PDAF fast focusing meet professional broadcast requirements.
- Virtual production and XR studios: free-D protocol outputs precise PTZ tracking data, enabling seamless integration of live actors and virtual backgrounds with 3D production software.
- High-end enterprise meeting rooms and boardrooms: broadcast-grade image quality + AI tracking enhance the visual experience of important meetings.
- Educational lecture capture and premium course recording: 4K 60fps detailed image quality + AI tracking meet the requirements of university premium courses and MOOC recording.
- Government and enterprise emergency command centers: multi-interface output + highly reliable PTZ, suitable for complex system integration in command and dispatch scenarios.
ODM Customization Options
- Sensor and lens customization: sensor specifications, optical zoom ratio, wide-angle field of view can be adjusted, or sensors can be replaced with specific wavelength bands (near-infrared, ultraviolet).
- AI algorithm customization: ReID/FaceID algorithms can be optimized for specific industry scenarios, such as instrument tracking in medical surgery or equipment recognition in industrial scenarios.
- Interface and protocol customization: interface types can be added or removed (e.g., more SDI channels, fiber output), or specific protocol support can be customized (e.g., SRT, RIST, industry-private protocols).
- Structure and appearance customization: body color, logo printing, mounting base form (ceiling, wall, tripod, vehicle shock-absorbing mount).
- Firmware function customization: deep customization of preset strategies, auto-tracking sensitivity, Tally light logic, privacy cover linkage, and other functions.
- White-label: complete ODM white-label service, with full-chain customization from appearance, packaging, and manuals to firmware UI.
