Falcon-900MGS: Solving Label & QR Misreads with Sony Pregius S Global Shutter Technology
On most production lines, label and code verification isn’t complicated on paper. but the conditions around it usually are. Bright reflective labels can wash out details; some printers produce barely readable codes, and lighting changes from station to station. Add a bit of conveyor movement, and many cameras start to struggle. System integrators want a global-shutter camera that keeps images clean and consistent without extra tuning while staying compact enough for small inspection modules.
Vadzo’s Falcon-900MGS, built around Sony’s Pregius S™ IMX900 global-shutter sensor, has become a preferred choice for these environments. Its Quad HDR, excellent NIR response, and driver-free UVC architecture enable highly reliable scanning and code verification on diverse label materials and conveyor setups. This case study outlines how the Falcon-900MGS improved code-reading consistency and eliminated integration issues in a production labeling line.

Customer Requirements
A vision-system integrator needed to add automated label and barcode validation to an industrial production line. For their inspection module, the camera had to:
Read 1D barcodes, 2D DataMatrix, and QR codes on matte, glossy, and reflective label surfaces
Handle code variability: faded print, stretched labels, low contrast, micro-scratches, and partial occlusions
Avoid rolling-shutter distortions that previously caused blurred or skewed codes
Maintain consistent contrast despite mixed lighting (white LEDs + NIR backlights)
Support plug-and-play operation with OpenCV, ZBar, and commercial code-reading engines
Fit inside a compact inspection module without adding weight or requiring enclosure redesign
Provide stable operation across Windows and Linux without custom drivers
Deliver a minimum of 20–50 inspections per minute, with deterministic timing and low latency
The customer also required a scalable solution; new lines, new workstations, or OS re-images must be able to deploy the same camera without driver conflicts or SDK installation overhead.
Application Challenges
Label and barcode inspection in real factories is more complex than simple “static barcode reading.” The customer faced:
Lighting & Surface Challenges
Glossy laminated labels caused specular reflections and washed-out modules
White matte labels appeared underexposed under bright overhead light
Some stations used NIR backlighting, demanding strong IR sensitivity
Shifts in ambient lighting caused inconsistent exposure throughout the day
Geometry & Motion Challenges
Conveyor vibration introduced micro-blur in rolling-shutter cameras
Labels were sometimes angled or unevenly applied, causing perspective skew
Small working distance demanded a compact camera and low-distortion optics
Integration Challenges
Previous cameras required heavy driver installation and frequent updates
OS patches or workstation re-imaging often broke driver compatibility
Decoding engines failed intermittently due to inconsistent image quality
These problems caused under-reads, manual re-labeling, rework cycles, and lost production time.

Implementation & Immediate Improvements
Integration took minutes; plug in via USB, open the inspection software, and the camera appeared instantly. No driver packages, no SDK conflicts.
Observed Improvements
1. Perfectly sharp modules on all codes: Global shutter eliminated motion artifacts, enabling reliable decoding even when the conveyor wasn’t perfectly steady.
2. HDR stabilized contrast on glossy and laminated labels: Previously unreadable labels especially those with specular streaks, became consistently decodable.
3. NIR lighting produced crisp, uniform codes: Mixed lighting no longer caused failures; IR edge or backlighting worked flawlessly.
4. Zero downtime from vision-related issues: Inspection stabilized, decoding rates increased, and operator interventions were eliminated.
A senior automation engineer summarized it clearly: “We went from inconsistent barcode scans to 100% readability across shifts. The Falcon-900MGS fixed every lighting problem we struggled with.”
Results & Measurable Impact
Across the first two production lines:
Scan/read error rate: Reduced from 6–8% to 0%
Re-inspection time: Eliminated completely
Lighting adjustments: Reduced by ~90%
Workstation setup time: Cut from hours to minutes
Operator interventions: Reduced to zero
The lightweight, compact camera enabled direct replication of the solution onto additional lines without mechanical changes or recalibration. Production throughput increased simply by eliminating code-reading exceptions.
