Next-Generation 4K Imaging with AI Optics

The Bolin EXU420N 4K60 Outdoor NDI PTZ Camera represents a breakthrough in remote weatherproof imaging, delivering pristine, broadcast-grade Ultra HD video across complex outdoor landscapes. Equipped with the proprietary Bolin BM4620 image module, the system houses a high-class 1/2.8-inch Sony IMX715 CMOS sensor mated to an 8-megapixel ultra-high-resolution 20x optical zoom lens. Powered by an AI-driven image signal processing (ISP) algorithm, the camera intelligently isolates human profiles to execute precise AI Face Detection Auto Focus and Auto Exposure adjustments. Spanning a wide 78.59° horizontal field of view down to tight telephoto frames, the EXU420N captures crisp, noiseless 4K visuals at a smooth 60 frames per second, making it the perfect equipment choice for live stadium sports, outdoor concert stages, weather decks, and remote television broadcasts.

Global WAN Production via NDI Embedded Bridge

As a native centerpiece for modern decentralized production workflows, the EXU420N is uniquely equipped with NDI Embedded Bridge technology. This advanced function allows the camera to act as a standalone gateway, compressing and sending encrypted NDI streams directly across wide area networks (WAN) to any location globally without requiring external hardware or complex local network configurations. Production crews can seamlessly access real-time collaboration, bi-directional control, and secure, ultra-low latency AV-over-IP streams across multiple venues or remote broadcast hubs. Operating with certified NDI High Bandwidth, NDI HX3, and NDI 6 readiness, the camera fits perfectly into any contemporary NDI ecosystem.

Advanced Studio Tracking and Phase Alignment

Built to accommodate interactive live television environments, the EXU420N features integrated support for the industry-standard FreeD (Free Dimensional Video) tracking protocol. The robotic drive mechanism continuously outputs real-time, ultra-low latency spatial telemetry data—including exact pan, tilt, zoom, and focus metrics—allowing external augmented reality (AR) and virtual reality (VR) software engines to sync physical camera paths with immersive digital sets. For traditional baseband master control switchers, a dedicated BNC Genlock input provides strict phase timing synchronization. This keeps frame boundaries perfectly aligned in multi-camera configurations, eliminating switching delays, video artifacts, and signal drops.

Comprehensive Connectivity and Meteorological Defense

The rugged back panel interface suite provides spectacular configuration flexibility, sustaining true independent dual-output performance across baseband hardware and network routes. Broadcasters can deploy pristine local hardware video over dual 12G-SDI ports, an HDMI 2.0 interface, and a dedicated SFP Optical SDI slot designed for long-distance glass fiber runs, while simultaneously pushing NDI, SRT, RTSP, or RTMP network layers. Balanced XLR broadcast audio lines are securely integrated using a waterproof 10-pin LEMO breakout connection. Protected by an IP67-rated weatherproof housing featuring an integrated heater and defroster system, the camera thrives in punishing weather conditions ranging from –40 °C to 60 °C and withstands wind loads up to 60 m/s. Fully NDAA compliant, the camera supports efficient single-cable drops via high-power PoE++ links, incorporates a built-in tally light, and allows for clean remote firmware upgrades over IP networks.
