Vadzo Imaging’s MerlinPlus USB 2.0 camera series expands with two new camera products powered by the Sony STARVIS 2 IMX662 and Onsemi AR0521 sensors, bringing native HDR, high dynamic range ISP processing, onboard storage, dual endpoint streaming, and UVC plug-and-play compliance to cost-sensitive OEM programs in kiosk, medical device, automation, robotics, and smart city deployments.
FORT WORTH, TX / ACCESS Newswire / April 28, 2026 / Vadzo Imaging, a provider of embedded vision camera products, is expanding its MerlinPlus USB 2.0 UVC camera portfolio to address a challenge that product teams in cost-sensitive OEM programs encounter consistently: finding a USB 2.0 camera that delivers genuine imaging performance without the system cost or interface complexity of USB 3.0 or higher. The two new camera products in the MerlinPlus series are built around this objective, offering sensor-level imaging capability, HDR, and edge features within the USB 2.0 bandwidth envelope that many embedded and portable products already rely on.

The expansion brings two distinct sensor configurations into the MerlinPlus lineup. One addresses ultra-low light and HDR imaging at 1080p resolution with a Sony STARVIS 2 sensor. The other delivers 5MP resolution with low noise characteristics and ISP-level HDR processing capability using an Onsemi sensor. Together, they give OEM engineering teams a choice between low-light HDR priority and resolution priority within a shared platform and form factor.
Why USB 2.0 Remains the Right Interface for Cost-Sensitive OEM Deployments
For many embedded product categories, including kiosk camera, medical imaging camera, portable inspection devices, and robotics vision units, USB 3.0 brings bandwidth that the application does not need and cost and power implications that the BOM cannot support. USB 2.0 provides enough throughput for 1080p video at standard frame rates and is natively supported across virtually every host platform without additional controller hardware. A high dynamic range USB 2.0 camera that combines sensor-level performance with UVC compliance removes driver dependencies and simplifies integration across Windows, Linux, and Android host environments.
The MerlinPlus camera series is built to serve exactly this segment. Both camera products in this expansion use the USB 2.0 Micro B interface, operate as UVC-compliant plug-and-play devices, support GPIO for hardware integration, and are powered entirely from the USB bus. This makes them practical for battery-powered and single-board-computer deployments where a separate power rail is not available.
MerlinPlus-662CRS IMX662 Color 1080P HDR USB 2.0 Onboard Storage Camera
The MerlinPlus-662CRS Sony IMX662 USB 2.0 camera in the MerlinPlus series is built around the Sony STARVIS 2 IMX662 sensor, a back-illuminated 1/2.8″ device with 2.9 µm pixels designed for low-lux performance. It delivers 2MP resolution at 1920 x 1080 and supports both 1080p and 720p output modes. The Sony STARVIS 2 architecture enables this 2MP USB 2.0 color camera to produce clean and detailed images in ambient lighting conditions where conventional sensors require supplemental illumination. Native HDR at the sensor level means that high-contrast scenes with bright and dark regions in the same frame are handled without post-processing overhead on the host side.
For applications that require wide-angle coverage, this 1080p color USB 2.0 camera supports lens field of view options up to 200 degrees DFOV through its S-Mount M12 optics interface and incorporates onboard dewarping. This makes a single unit viable for room-level coverage in kiosk and digital signage deployments, retail analytics, and patient monitoring environments where a wide field of view matters more than pixel count.
One of the more operationally useful features in this IMX662 rolling shutter USB 2.0 camera is Dual Endpoint Streaming. The camera is capable of delivering simultaneous video streams to two separate endpoints over a single USB connection. In practice, this means a device can receive a primary stream for live display or inference while a secondary stream is routed to an onboard storage module or a secondary processing pipeline without any additional hardware. The onboard storage capability allows image data to be retained locally on the device itself, which is relevant for applications like unmanned kiosk systems, field inspection tools, and edge AI devices where network connectivity is intermittent or unavailable. This combination of dual endpoint streaming and onboard storage gives product teams the architecture they need for both real-time and offline use cases from a single IMX662 USB 2.0 camera module.
Key Specs: 2MP (1920 x 1080) | Sony STARVIS 2 IMX662 | Rolling Shutter | Native HDR | USB 2.0 Micro-B | 1/2.8″ Sensor | 2.9 µm Pixel Size | S-Mount (M12)
MerlinPlus-521CRS AR0521 On-Board Storage Color 5MP USB 2.0 Camera
The MerlinPlus-521CRS onsemi ar0521 usb 2.0 camera in the MerlinPlus series is built around the Onsemi AR0521 sensor, a 1/2.5″ device with 2.2 µm pixels. It delivers 5MP resolution at 2592 x 1944 and supports 1080p and 720p streaming modes over USB 2.0. The AR0521 is well regarded for its low-noise characteristics, which make it a strong choice for applications where image clarity in normal to moderate lighting conditions matters more than extreme low-light performance. This 5MP USB 2.0 color camera brings a meaningful resolution advantage over 2MP alternatives while staying within the USB 2.0 interface budget and the 38mm x 38mm form factor.
On the HDR front, the AR0521 USB 2.0 camera supports Line Interleaved T1/T2 Readout, which enables HDR image processing to be handled in the ISP chip. This approach uses alternating short and long exposure rows within the same frame to allow the downstream ISP to reconstruct a high dynamic range output without requiring a full multi-frame capture sequence. For OEM design teams building products around a host-side ISP pipeline, this is a practical way to extend the camera’s dynamic range capability without a hardware redesign. The result is a 5MP USB 2.0 camera that can adapt to mixed lighting environments typical in kiosk, patient care, and smart city installations.
Like its counterpart, this MerlinPlus-521CRS ar0521 rolling shutter USB 2.0 camera supports Dual Endpoint Streaming and onboard storage. The ability to route video simultaneously to two distinct endpoints over one USB connection makes it practical to run a live preview for a user interface while simultaneously writing frames to local storage or a secondary analytics pipeline. Onboard storage ensures data availability independent of network conditions, which is particularly relevant for smart parking, retail AI, and field deployment scenarios. For applications using the 1080p color USB 2.0 camera and the 720p color USB 2.0 camera output modes, the available USB 2.0 bandwidth provides sufficient headroom to support sustained dual endpoint operation.
Key Specifications: 5MP (2592 x 1944) | onsemi AR0521 | Rolling Shutter | External HDR (Line Interleaved T1/T2 Readout – ISP side Processing) | USB 2.0 Micro-B | 1/2.5″ Sensor | 2.2 µm Pixel Size | S-Mount (M12)
“OEM customers in cost-driven product categories need imaging performance that does not come with unnecessary interface overhead. The MerlinPlus USB 2.0 expansion brings HDR imaging, onboard storage, and dual endpoint streaming into a plug-and-play USB 2.0 form factor that their existing host systems can adopt without redesign. That is what cost-sensitive OEM deployment actually requires.” – Alwin Vincent, Product Manager, Vadzo Imaging
