“The MerlinPlus‑234CGS is a 2MP global shutter USB camera that records directly to on‑board storage while streaming over USB. Built on the Onsemi AR0234 color global shutter sensor, it eliminates motion blur for high‑speed robotics, traffic monitoring, smart security, and video surveillance – all in a compact UVC‑compliant module.”
FORT WORTH, TX / ACCESS Newswire / June 2, 2026 / Vadzo Imaging, a provider of embedded vision solutions, today launched the MerlinPlus‑234CGS, a 2MP global shutter camera that combines the Onsemi AR0234 color global shutter sensor with on‑board microSD storage and USB 2.0 UVC interface. Unlike standard Rolling shutter USB cameras, the MerlinPlus‑234CGS captures fast‑moving objects without distortion. Its color global shutter architecture freezes motion across every pixel simultaneously, while the built‑in storage enables local recording independent of a host PC. This USB UVC camera serves robotics perception, automated traffic enforcement, smart security checkpoints, and industrial video surveillance.
Sensor and Camera Overview
The MerlinPlus‑234CGS uses the Onsemi AR0234 CMOS color global shutter sensor – a 2MP (1920 x 1080) imager with a 1/2.6‑inch optical format and 3.0 µm pixels. The global shutter exposes and reads all pixels simultaneously, eliminating the “jello effect” and skew common in rolling shutter sensors. For traffic monitoring camera applications – reading license plates on speeding vehicles and robotics camera tasks like conveyor belt inspection, this means sharp, artifact‑free frames. The sensor’s color performance and high quantum efficiency deliver clean 1080p video at 60 fps.
The camera integrates a microSD card slot for on‑board storage (up to 128 GB) and a USB 2.0 interface with UVC (USB Video Class) compliance. It enumerates as a standard webcam on Windows, Linux, Android, and macOS – no proprietary drivers required. A factory‑fitted S‑mount (M12) lens holder comes with an adjustable‑focus lens pre‑calibrated for working distances from 0.3 m to 5 m.

Key Capabilities of the MerlinPlus ‑ 234CGS 2MP Global Shutter USB Camera
Global Shutter Eliminates Motion Blur for High ‑ Speed Scenes
Most USB cameras use rolling shutters, which capture rows sequentially – fast‑moving objects appear skewed or stretched. The AR0234’s global shutter captures the entire 2MP frame at the same instant. For video surveillance camera systems monitoring passing forklifts or smart security camera gates scanning running individuals, this delivers crisp, evidence‑grade images without motion artifacts.
On ‑ Board Storage for Edge Recording
The MerlinPlus‑234CGS writes video or stills directly to a microSD card, independent of the USB host. If the connected PC crashes or loses power, the camera continues recording locally. For traffic enforcement, this means no lost violation of footage. For robotics, it provides redundant logging. Users can configure recording triggers (motion, continuous, or software command) via simple UVC controls.
USB 2.0 UVC – Plug ‑ and ‑ Play, No Driver Hassle
As a USB UVC camera, the MerlinPlus‑234CGS works instantly with any operating system supporting UVC – Windows 10/11, Linux (including ROS), Android, and macOS. No proprietary SDK required. This USB 2.0 camera enumerates as /dev/video0 on Linux or as a generic webcam on Windows, ready for OpenCV, GStreamer, or custom applications.
Dual Endpoint Streaming for Simultaneous Use
The camera exposes two USB endpoints: one for full‑resolution 1080p at 60 fps, another for scaled 720p or VGA at lower bandwidth. A robotics system can stream 1080p to a vision processor while sending a 720p preview to a remote dashboard – all from one physical camera. This dual endpoint streaming USB camera architecture is unique at this price point.
Color Global Shutter for Inspection and Tracking
Unlike monochrome global shutter sensors common in industrial cameras, the AR0234 delivers rich color global shutter output. For traffic monitoring camera applications requiring vehicle color identification, or for robotics camera tasks differentiating colored parts on a fast conveyor, a color global shutter is essential. The MerlinPlus‑234CGS also supports 720p and 1080p global shutter modes, making it a versatile 1080p global shutter camera and 720p global shutter camera in one.
Easy Integration with ROS, OpenCV, and Custom Code
Vadzo provides sample Python scripts to capture global shutter frames via V4L2 (Linux) or DirectShow (Windows). For ROS2, a ready‑to‑use camera node publishes raw and compressed image topics. Developers can enable on‑board storage recording through USB control transfers – documented in the product’s technical reference manual.
“Engineers building automated inspection or security systems repeatedly tell us: rolling shutter artifacts ruining machine vision and losing footage due to PC failure is unacceptable. The MerlinPlus ‑ 234CGS solves both. We paired Onsemi’s AR0234 color global shutter with on ‑ board microSD storage and USB UVC – the easiest camera to integrate for high ‑ motion environments.”- Alwin Vincent, Product Manager, Vadzo Imaging
Applications
Robotics & AGV camera: The MerlinPlus-234CGS is a 2MP global shutter USB camera for robotics that eliminates the rolling shutter skew that corrupts object detection and pose estimation on fast-moving conveyor systems, robotic arms, and AGVs. Autonomous mobile robots and conveyor inspection systems running at 0.5-2 m/s generate motion-skewed frames on rolling shutter cameras, causing misclassification errors in YOLO and other vision models. The AR0234’s simultaneous full-frame exposure captures distortion-free 1080p@60fps regardless of platform velocity. On-board microSD logs telemetry and vision frames locally, if the USB host crashes mid-run, no footage is lost. UVC compliance means zero-driver integration on ROS2, V4L2 Linux, and Jetson platforms.
Traffic monitoring & LPR camera: The MerlinPlus-234CGS is a traffic monitoring camera that reads license plates on vehicles moving at 60+ mph without motion blur, using a color global shutter sensor that exposes all pixels simultaneously. Rolling shutter traffic cameras produce diagonal plate smear above 40 mph, unusable for automated number plate recognition (ANPR/LPR). The AR0234 global shutter freezes the full frame at the same instant, delivering evidence-grade 1080p images at every trigger pulse. Local microSD recording ensures no plate frames are lost if the network link drops at a toll point or intersection. The >110 dB HDR mode handles glare from headlights and direct sun without saturating plate characters.
Smart security & access control camera: The MerlinPlus-234CGS is a smart security camera with global shutter that captures sharp images of fast-moving people and vehicles at access control gates, perimeter checkpoints, and entry points, where rolling shutter blur makes face and badge recognition unreliable. Access control systems scanning individuals walking at normal pace (1.2-1.5 m/s) produce blurred face crops with rolling shutter cameras, degrading FR accuracy below acceptable thresholds. The AR0234 global shutter eliminates this regardless of subject velocity. USB UVC compliance connects directly to NVR software (Blue Iris, Milestone, Genetec) or edge AI boxes (Jetson, Hailo) without drivers. Dual-endpoint streaming sends 1080p to the recognition engine and 720p simultaneously to a monitoring dashboard.
Video surveillance & facility monitoring: The MerlinPlus-234CGS is a video surveillance camera with on-board microSD storage that records continuously to local storage independent of the host PC, providing tamper-proof, network-failure-resilient footage for manufacturing lines, laboratories, and secure facilities. Surveillance deployments in manufacturing and lab environments frequently lose footage due to network interruptions or host PC reboots during shift changes. The MerlinPlus-234CGS writes H.264/MJPEG continuously to microSD (up to 128 GB) while simultaneously streaming over USB, two independent failure domains. Motion-triggered recording conserves storage. The global shutter captures every worker action and equipment movement without the rolling artifact that affects fast conveyor and robotic arm surveillance.
Industrial inspection camera: The MerlinPlus-234CGS is a global shutter USB camera for industrial inspection that captures sharp, artifact-free images of fast-moving parts on sorting lines, print inspection systems, and PCB assembly verification, without the distortion that rolling shutter cameras introduce at conveyor speeds above 0.3 m/s. Print inspection at 300 dpi requires every character to be resolved without smear. PCB solder joint verification requires pixel-accurate geometry at production line speed. The AR0234 color global shutter delivers 2MP color frames with no inter-line skew, connecting to any industrial PC via USB 2.0, no frame grabber, no GigE, no Camera Link.
Frequently Asked Questions (FAQs)
What is a global shutter USB camera and why does it matter for robotics?
A global shutter USB camera exposes all pixels simultaneously in a single instant, eliminating the motion distortion and rolling shutter skew that makes fast-moving objects appear stretched or diagonal in standard webcams and USB cameras. Rolling shutter sensors read rows sequentially from top to bottom. At conveyor speeds above 0.3 m/s or robot arm velocities above 0.5 m/s, this creates frame distortion that corrupts object detection bounding boxes, OCR outputs, and pose estimation coordinates. The MerlinPlus-234CGS uses the Onsemi AR0234 color global shutter, which captures all 2MP pixels at the same microsecond, delivering distortion-free 1080p@60fps regardless of scene velocity. For robotics, AGV navigation, and conveyor inspection, this is the difference between reliable machine vision and unpredictable failures.
Can the MerlinPlus-234CGS read license plates on moving vehicles?
Yes. The MerlinPlus-234CGS reads license plates on vehicles moving at 60+ mph using its AR0234 color global shutter, which freezes the entire frame simultaneously and eliminates the diagonal smear that makes plates unreadable on rolling shutter traffic cameras. Standard rolling shutter cameras used in traffic monitoring produce plate smear above 40 mph. The AR0234 global shutter captures the full 1920×1080 frame in a single exposure event, delivering sharp, character-resolved plate images at all legal traffic speeds. The >110 dB HDR mode prevents highlight clipping from headlights and direct sun. On-board microSD stores every plate capture locally.
Does the MerlinPlus-234CGS work with ROS2 and Linux without drivers?
Yes. The MerlinPlus-234CGS is a UVC-compliant USB camera that works on ROS2, Linux V4L2, OpenCV, and GStreamer with zero driver installation, it enumerates as /dev/video0 on any Linux kernel out of the box. UVC (USB Video Class) compliance means the camera uses the kernel’s built-in uvcvideo driver, which is present in every mainstream Linux distribution and Android build. On ROS2, the standard usb_cam package publishes raw and compressed image topics immediately. The camera has been validated on Jetson Orin, RK3588, Raspberry Pi 5, and standard x86 Ubuntu. Vadzo provides a ready-to-use ROS2 camera node and Python/GStreamer sample scripts in the product’s technical reference documentation.
What is dual endpoint streaming and how does it work?
Dual endpoint streaming means the MerlinPlus-234CGS simultaneously outputs two independent video streams over a single USB cable, full-resolution 1080p@60fps to one consumer (e.g. a vision processor) and 720p or VGA to another (e.g. a remote monitoring dashboard). Most USB cameras expose a single UVC endpoint, only one application can consume the stream at a time. The MerlinPlus-234CGS exposes two endpoints on the same USB connection. A robotics system can route 1080p frames to a YOLO inference engine running on a Jetson while simultaneously sending a 720p stream to a remote supervisor dashboard, both at full frame rate, from one physical camera, over one USB cable. This eliminates the need for a software frame duplicator or a second camera for monitoring.
How does on-board microSD storage work on the MerlinPlus-234CGS?
The MerlinPlus-234CGS records video and images directly to an on-board microSD card (up to 128 GB) independent of the USB host, if the connected PC loses power or crashes, the camera continues recording locally without interruption. The on-board storage operates as a second, independent recording path, the camera writes to microSD at the same time it streams over USB. Users configure the recording mode (continuous, motion-triggered, or software-commanded) via standard UVC control transfers, documented in the technical reference manual. For traffic enforcement, this means zero lost violation footage during network outages. For industrial robotics, it provides a redundant log for post-incident analysis. Storage capacity supports approximately 8-12 hours of continuous 1080p MJPEG recording on a 128 GB card.
What frame rate does the MerlinPlus-234CGS support at 1080p, and does USB 2.0 limit it?
The MerlinPlus-234CGS streams 1080p at 60fps over USB 2.0 without dropped frames, using H.264 compression at approximately 160 Mbps. In practical terms, this means the camera runs reliably on USB 2.0 ports on older industrial PCs and embedded boards without requiring a USB 3.0 upgrade. Cable length is also a practical advantage: USB 2.0 runs reliably at 5-10 m with standard extenders, whereas USB 3.0 cameras typically require cables under 3 m. At 720p, the camera achieves 100fps for high-speed inspection applications.
Is the MerlinPlus-234CGS suitable for low-light factory and warehouse environments?
Yes. The AR0234’s 3.0 µm pixel with Onsemi DR-Pix technology delivers clean 1080p video at 20 lux while the global shutter eliminates motion blur from fast-moving forklifts and conveyor belts in the same frame. Most global shutter sensors sacrifice low-light sensitivity for speed. The AR0234’s 3.0 µm pixel is larger than typical global shutter designs, providing approximately 2× better low-light sensitivity than the AR0135 and comparable sensors. At 20 lux, signal-to-noise ratio is sufficient for reliable object detection without supplemental lighting. The global shutter eliminates the “jello effect” from forklifts and robotic arms moving through the frame, a combination that rolling shutter cameras cannot match even with additional illumination.
