Built on the Onsemi AR0544 HyperLux LP, a 1/4.2″ BSI Stacked CMOS sensor with 1.4 µm pixel pitch, 60 fps, eDR and LI-HDR modes, and Wake on Motion, the Bolt-544MRS is a purpose-built AR0544 Low Power MIPI CSI-2 Camera that joins Vadzo’s MIPI camera series as a compact, V4L2-compatible module for NVIDIA Jetson and Raspberry Pi platforms over 2-lane MIPI CSI-2.
FORT WORTH, TX / ACCESS Newswire / June 17, 2026 / Vadzo Imaging, a provider of embedded vision camera solutions, today announces the launch of the Bolt-544MRS, an AR0544 MIPI CSI-2 Camera with monochrome rolling shutter, purpose-built for OEM teams building low-power, high-resolution imaging products. As a core module in the over 2-lane MIPI CSI-2 with validated V4L2 drivers for Jetson and Raspberry Pi out of the b Vadzo’s MIPI CSI-2 camera series, the Bolt-544MRS delivers 5MP BSI monochrome output.
Sensor and Camera Overview
The Bolt-544MRS is built on the Onsemi AR0544 sensor, a 1/4.2″ Back-Side Illuminated (BSI) Stacked CMOS rolling shutter sensor with 1.4 µm × 1.4 µm pixel pitch, 2592×1944 resolution, and a 60 fps maximum frame rate. The monochrome variant removes the Bayer filter entirely, directing full photon flux, including enhanced NIR response at 850 nm and 940 nm, to every pixel. As an AR0544 MIPI CSI-2 Camera, the Bolt-544MRS delivers this output directly to the host SoC ISP over 2-lane MIPI CSI-2, with no USB or network overhead in the pipeline.
The sensor supports eDR and LI-HDR modes for high-contrast scenes, multiple subsampling modes (binning, summing, skipping, windowing) for bandwidth and resolution management, and Wake on Motion (WOM) for power-gated deployments. The Bolt-544MRS supports video streaming at 1080p AR0544 MIPI Camera output, 720p AR0544 MIPI CSI-2 Camera output, and full 5MP monochrome rolling shutter resolution. The camera accepts S-Mount (M12) optics, operates across −30°C to 85°C, and provides module-level V4L2 drivers for Raspberry Pi 4, Raspberry Pi 5, Jetson Orin NX, Jetson Orin Nano, Jetson Orin AGX, and NXP i.MX8M Plus. Driver porting for NXP i.MX, STM, and MediaTek platforms are available on request.

Key Capabilities of the Bolt-544MRS: AR0544 MIPI CSI-2 Camera with Monochrome Rolling Shutter
BSI Architecture and Low-Power Design for Battery-Operated OEM Products: Most embedded vision deployments for wearable devices, patient monitoring, and portable diagnostic imaging platforms fail on one of two constraints: the sensor draws more power than the battery budget allows, or the pixel architecture does not deliver adequate sensitivity in low-illumination environments. The AR0544 HyperLux LP platform addresses both. The BSI Stacked CMOS architecture maximizes photon collection per pixel at the 1.4 µm pitch level by placing interconnect layers behind the photodiode rather than in front of it. Combined with the HyperLux LP power architecture, Onsemi positions it as the lowest power consumption among comparable 5MP sensor offerings. The Bolt-544MRS delivers full 5MP imaging within the power envelope that standard sensors cannot reach at equivalent resolution. For OEM teams building wearable camera systems, portable medical device platforms, and battery-operated edge deployments, this AR0544 MIPI CSI-2 Camera resolves the power-versus-resolution tradeoff at the sensor level.
Monochrome BSI Sensor for NIR Sensitivity and High-Contrast Imaging: Color sensors carry two compounding sensitivity penalties in NIR and low-light environments: the Bayer filter absorbs the majority of incident photons to separate color channels, and front-side illumination at small pixel pitches further reduces effective collection area per pixel. The Bolt-544MRS AR0544 Monochrome MIPI CSI-2 Camera eliminates both. The monochrome architecture removes the filter layer, and the BSI structure directs full photon flux, including enhanced NIR response at 850 nm and 940 nm, to every 1.4 µm pixel. The result is a NIR-sensitive camera output that color sensor equivalents at the same pixel pitch cannot match without active NIR illumination compensation. For retinal imaging camera, diagnostic imaging camera, and monochrome medical camera deployments where contrast accuracy drives clinical performance, this advantage is measurable in SNR and spatial resolution.
eDR, LI-HDR, and Subsampling Modes for Demanding Scene Conditions: Enhanced Dynamic Range (eDR) and Line Interleaved HDR (LI-HDR) modes extend the AR0544’s usable dynamic range for scenes mixing direct illumination with shadowed areas, a routine challenge in security camera and industrial inspection camera environments. Multiple subsampling modes – binning, summing, skipping, and windowing allow OEM teams to trade resolution for frame rate or reduce output bandwidth to match SoC processing capacity within the same AR0544 MIPI CSI-2 Camera platform. Wake on Motion (WOM) adds power-gating for deployments where the sensor activates only on detected scene change, directly applicable to smart access and low-power surveillance applications.
Low-Latency 2-Lane MIPI CSI-2 Interface with Validated V4L2 Drivers: The Bolt-544MRS AR0544 MIPI CSI-2 Camera connects directly to the SoC ISP via 2-lane MIPI CSI-2, delivering deterministic, low-latency frame data with no USB enumeration overhead, no network stack, and no host-side buffering to introduce pipeline jitter. V4L2 module-level drivers for Raspberry Pi 4, Raspberry Pi 5, Jetson Orin NX, Jetson Orin Nano, Jetson Orin AGX, and NXP i.MX8M Plus ships out of the box. For edge AI camera module deployments and embedded Linux camera systems where consistent frame timing is a hard system requirement, this custom MIPI camera module, a validated MIPI CSI-2 camera module, delivers the interface reliability that USB and GigE architectures cannot match at equivalent power budgets.
Rolling Shutter: Right Architecture for the Right Applications: Rolling shutter reads pixel rows sequentially, introducing geometric distortion only when fast-moving subjects or camera motion occur during readout. For applications where subjects are stationary or slow-moving, such as digital microscopy, patient monitoring, smart access, and retail analytics, rolling shutter delivers the full sensitivity, HDR, and resolution benefit of the AR0544 architecture with no visible artifact. The Bolt-544MRS AR0544 Low Power MIPI CSI-2 Camera is purpose-built for this class of OEM application, where the HyperLux LP power profile, BSI sensitivity, 5MP resolution, WOM, and eDR modes are the deciding factors. For high-speed mechanical inspection or rotating component imaging, Vadzo’s global shutter embedded vision camera portfolio is the right alternative, and Vadzo publishes both options precisely so OEM teams can make that call on technical grounds.
Compact Board-Level Form Factor for Space-Constrained OEM Integration: The Bolt-544MRS packages full 5MP resolution MIPI camera output into a compact, board-level module that drops directly into OEM PCB layouts. The S-Mount (M12) lens mount allows field-of-view and focal length configuration within the same AR0544 MIPI CSI-2 Camera platform without board-level changes. The 1/4.2″ optical format is physically compatible with AR/VR/XR headsets, wearable camera enclosures, and handheld medical device camera designs where sensor size is a hard integration constraint. The −30°C to 85°C operating range covers outdoor security camera infrastructure and industrial environments where consumer-grade sensor modules fail on thermal grounds.
“The Bolt-544MRS is built around a specific engineering trade-off: the AR0544 HyperLux LP delivers 5MP BSI monochrome imaging with the lowest power consumption at this resolution class, enhanced NIR response at 850 nm and 940 nm, eDR and LI-HDR modes, and Wake on Motion all in a 1/4.2″ form factor that fits wearable, medical, and smart access enclosures. It is not a global shutter camera, and it does not need to be for the applications it targets. For OEM teams where power budget, BSI sensitivity, and 5MP resolution have to coexist in a compact module, this AR0544 MIPI CSI-2 Camera is what the Bolt-544MRS is built to deliver.” – Alwin Vincent, Product Manager, Vadzo Imaging.
Target Applications
Medical Imaging, Patient Monitoring, and Wearable Diagnostic Devices: Portable and wearable medical devices impose a demanding combination of constraints: high spatial resolution and low-noise output for clinical utility, a power budget that battery capacity sets, and an enclosure sized for patient comfort or handheld use. Standard 5MP sensors exceed the power budget; lower-resolution sensors sacrifice the image quality that diagnostic workflows require. The Bolt-544MRS AR0544 MIPI CSI-2 Camera resolves this directly: the HyperLux LP BSI architecture delivers 5MP monochrome output within the power envelope of battery-operated medical product designs. Patient monitoring systems where subjects are largely stationary operate cleanly within the rolling shutter architecture. As a low noise medical camera with enhanced NIR response, the Bolt-544MRS performs reliably under the reduced and variable illumination conditions common in clinical environments, giving OEM patient monitoring camera and biomedical imaging camera teams clinical image quality without exceeding battery or enclosure budgets.
Digital Microscopy, Retinal Imaging, and Laboratory Imaging: Digital microscope camera systems and retinal imaging camera platforms require spatial resolution to resolve fine specimen or retinal structure detail, monochrome architecture to avoid Bayer interpolation artifacts that degrade measurement accuracy at high magnification, and NIR sensitivity for fluorescence and near-infrared imaging modes. The Bolt-544MRS delivers all three from a single compact module. The 5MP BSI monochrome AR0544 sensor resolves fine detail without the luminance-to-color conversion overhead that RGB sensors introduce into laboratory image processing pipelines. For workflows operating under 850 nm and 940 nm NIR illumination, the filter-free BSI architecture of this AR0544 Mono MIPI Camera captures full photon flux, where color sensor alternatives produce noise-limited output. Specimens in microscopy setups are stationary, making rolling shutter geometrically accurate for the full range of digital microscope camera and laboratory slide scanning applications.
Smart Access, AR/VR/XR, and Retail Analytics: Smart access systems, video doorbells, access control terminals, and building entry camera deployments require a sensor that activates quickly on scene change, delivers sharp imaging under variable daylight and NIR illumination, and operates within the power budget of always-on edge deployments. The AR0544’s Wake on Motion (WOM) keeps the sensor in a power-gated state until motion is detected, extending battery or PoE budgets in continuous monitoring applications. The enhanced NIR response at 850 nm and 940 nm supports night-mode operation under active IR illumination without a separate sensor. For AR/VR/XR headsets and retail analytics platforms where enclosure size and continuous power draw are hard constraints, the Bolt-544MRS AR0544 MIPI CSI-2 Camera delivers 5MP BSI monochrome output within the 1/4.2″ form factor and HyperLux LP power profile that larger-format sensors cannot match.
Industrial Inspection and Machine Vision: PCB inspection, surface quality analysis, dimensional measurement, and label reading on fixed or slow-moving substrates all require high spatial resolution, a clean monochrome luminance channel for machine vision algorithms, and a MIPI CSI-2 interface free of the timing variability that USB-based industrial inspection camera modules introduce. As an AR0544 Monochrome Camera delivering 5MP resolution over 2-lane MIPI CSI-2, the Bolt-544MRS provides the image quality and frame timing determinism these inspection pipelines require. For OEM teams building 1080p AR0544 Rolling Shutter MIPI Camera systems for quality control on fixed or slow-moving subjects, the Bolt-544MRS delivers validated drivers and the spatial resolution to resolve fine surface features reliably at production frame rates. For high-speed conveyor or rotating component inspection, Vadzo’s global shutter OEM embedded camera portfolio is the appropriate alternative.
Security, Surveillance, and Smart Infrastructure: Outdoor security infrastructure requires consistent detection performance across variable illumination, including NIR night-mode operation, where color sensor Bayer filter absorption creates a sensitivity deficit that degrades detection reliability. The Bolt-544MRS AR0544 MIPI CSI-2 Camera delivers NIR-sensitive monochrome output enhanced at 850 nm and 940 nm with 5MP spatial resolution, eDR, and LI-HDR modes for high-contrast outdoor scenes, and Wake on Motion for power-efficient always-on deployments. The −30°C to 85°C operating range covers outdoor thermal environments where consumer-grade sensor modules fail, and the 2-lane MIPI CSI-2 interface keeps the analytics pipeline free of the network latency that IP-based camera architectures introduce into real-time inference workflows.
Frequently Asked Questions
1. What is the best low-power 5MP MIPI CSI-2 camera for a wearable medical device or portable patient monitoring system?
Wearable and portable medical devices impose a hard combination of constraints: 5MP resolution for clinical image quality, low enough power consumption for battery operation, and a compact form factor for enclosure and weight budgets. Most 5MP sensors exceed the power budget or use front-side illuminated architectures that sacrifice sensitivity in clinical environments. The Vadzo Bolt-544MRS is built on the Onsemi AR0544 HyperLux LP sensor, a 1/4.2″ BSI Stacked CMOS device with 1.4 µm pixel pitch that Onsemi positions as the lowest power consumption among comparable 5MP offerings. The BSI monochrome architecture maximizes photon collection per pixel for reliable output in low-illumination clinical settings. The camera connects via 2-lane MIPI CSI-2 with validated V4L2 drivers for Jetson Orin and Raspberry Pi, and Vadzo provides full OEM camera customization, including enclosure design and lens holder modification for medical device integration.
2. Which 5MP monochrome MIPI camera supports Wake on Motion and HDR for smart access and video doorbell applications?
Smart access deployments require a sensor that activates only on scene change to minimize power consumption, delivers usable output under both daylight and NIR illumination, and handles the high-contrast scenes common at building entrances and doorways. The Vadzo Bolt-544MRS AR0544 MIPI CSI-2 Camera addresses all three requirements from a single platform. Wake on Motion (WOM) keeps the AR0544 in a power-gated state until motion is detected, then activates imaging directly extending battery or PoE power budgets in always-on deployments. Enhanced NIR response at 850 nm and 940 nm supports active IR illumination for night-mode operation without a separate NIR-optimized sensor. The eDR and LI-HDR modes handle high-contrast outdoor scenes where direct sunlight and deep shadow appear in the same frame. For OEM teams building smart access or video doorbell products, Vadzo provides validated V4L2 drivers for Jetson Orin and Raspberry Pi out of the box, and full OEM customization support, including board redesigns and enclosure design for production-ready deployment.
3. How does a 1/4.2″ BSI monochrome MIPI camera improve NIR imaging for retinal imaging and biomedical applications?
Color MIPI camera designs carry two compounding NIR limitations: the Bayer filter mosaic absorbs the majority of NIR photons, and front-side illuminated architectures reduce effective collection area per pixel at small pitches. The Vadzo Bolt-544MRS 1080p AR0544 Rolling Shutter MIPI Camera eliminates both at the sensor level. The monochrome architecture removes the filter layer, and the BSI structure directs full photon flux across visible and NIR spectrums to every 1.4 µm pixel, delivering higher SNR and reliable output for retinal imaging camera and biomedical imaging camera platforms, where color sensor alternatives produce noise-limited frames. The AR0544 HyperLux LP’s enhanced NIR response is a native sensor characteristic, not a firmware correction, so the Bolt-544MRS delivers genuine NIR performance from day one without tuning workarounds or additional optical hardware. Vadzo provides validated V4L2 drivers and full OEM customization support to move from evaluation to production efficiently.
4. When is a rolling shutter 5MP MIPI CSI-2 camera the right choice over a global shutter for embedded vision applications?
Rolling shutter reads pixel rows sequentially, introducing geometric distortion only when fast-moving subjects or rapid camera motion occur during readout. For the large class of embedded applications where subjects are stationary or slow-moving, digital microscope camera setups, patient monitoring, video conferencing, smart access terminals, AR/VR headsets, and retail analytics platforms, rolling shutter introduces no visible artifact and delivers the full sensitivity, resolution, and HDR benefit of the AR0544 architecture. The Vadzo Bolt-544MRS AR0544 Monochrome MIPI CSI-2 Camera is purpose-built for exactly these application classes, where the HyperLux LP power profile, BSI sensitivity, 5MP resolution, Wake on Motion, and eDR modes are the deciding specifications. For applications where fast-moving mechanical components or high-speed conveyors are in frame, Vadzo’s global shutter embedded vision camera portfolio is the technically correct choice, and Vadzo’s applications team will help you identify the right architecture before you commit to a design.
