Explore our factory-direct precision infrared thermal imagers, mobile smartphone attachments, and high-resolution thermal analyzers engineered for enterprise applications.
Shenzhen Dianyang Technology Co., Ltd. is a pioneer in uncooled infrared thermography, operating as a core subsidiary of VHD Technology Co., Ltd.
Shenzhen Dianyang Technology Co., Ltd. is a subsidiary of VHD (Shenzhen VHD Technology Co., Ltd.), a publicly listed company on the Shenzhen Stock Exchange. This strategic affiliation gives Dianyang unique access to VHD’s advanced R&D platforms, high-precision manufacturing systems, and rigorous quality management practices—enabling us to deliver thermal imaging products of higher reliability and consistency than typical ODMs.
We specialize in comprehensive ODM/OEM services for infrared thermal imaging solutions, including handheld thermal imagers, smartphone-connected thermal cameras, online desktop thermal analyzers, and high-performance thermal imaging telescopes. Our products serve global enterprise customers across power grid inspection, building diagnostics, firefighting search & rescue, industrial predictive maintenance, electronic PCB thermal distribution testing, and outdoor security monitoring applications.
Our dedicated engineering team applies Design for Manufacturing (DFM), Design for Testability (DFT), advanced thermal simulation, and EMC pre-compliance analysis to optimize performance and accelerate development cycles. We also support clients in obtaining key global certifications such as CE, FCC, RoHS, REACH, CB, UKCA, KC, and PSE.
Deep engineering analysis on uncooled VOx microbolometer evolution, edge-computing thermographic AI algorithms, and multispectral sensor fusion roadmap.
The thermal imaging industry is transitioning rapidly from 17μm pitch arrays toward 12μm and 8μm Vanadium Oxide (VOx) focal plane arrays (FPA). Shrinking pixel pitch allows Dianyang to integrate higher pixel counts (e.g., 640×512 or 1280×1024) into compact, lightweight optical enclosures while reducing optical aperture requirements without sacrificing field of view (FOV) or thermal sensitivity (NETD < 30mK).
Moving beyond simple visual heatmap generation, our next-gen DP and CA series imager architectures embed neural network processors directly into system-on-chip (SoC) microcontrollers. Edge AI enables real-time anomaly isolation, automatic temperature drift compensation, object classification (human vs. machinery vs. electrical busbars), and predictive fault warnings directly inside the device frame buffer.
Through dynamic sensor fusion algorithms, Dianyang integrates visible light RGB cameras with LWIR (Long-Wave Infrared, 8-14μm) microbolometers. Our proprietary image registration algorithm performs pixel-level overlay, fusing high-spatial-frequency visible contours onto radiometric thermal data to create crisp, high-definition thermograms that eliminate diagnostic ambiguity during field inspections.

Engineered to deliver quantitative thermal intelligence across high-stakes industrial, diagnostic, and research environments.
Prevent catastrophic blackout events by auditing high-voltage transformers, switchgears, busbars, and cable terminations. Dianyang's handheld DP series provides high radiometric resolution (up to 640x512) and telephoto narrow-FOV lenses to detect contact resistance anomalies from safe distances outside flash boundaries.
Identify thermal bridging, air infiltration, insulation voids, embedded moisture intrusion, and underfloor heating blockages. Smartphone thermal attachments (H1FB, H2FB) empower building surveyors with portable, instantly shareable thermographic reports directly from mobile devices.
The CA-30D benchtop thermal analyzer series provides sub-millimeter macro spatial resolution, allowing semiconductor engineers and circuit designers to track chip power dissipation, transient thermal runaway, short circuits, and heat sink efficiency during R&D prototyping phases.
Electric vehicle battery manufacturing demands strict continuous temperature profiling during cell formation, module welding, and pack testing. Online thermal analytics integrate seamlessly into automated conveyor lines to trigger early shutoff signals prior to battery thermal runaway events.
Designed to operate in dense smoke, total dark, and severe weather. High IP-rated robust thermal imagers and thermal night-vision monoculars allow firefighters and search-and-rescue personnel to spot human thermal signatures through thick smoke and foliage.
Integrating fixed-mount thermal cameras into industrial IoT frameworks using Modbus, Ethernet/IP, and RTSP protocols. Enables automated real-time thermal monitoring of critical rotary kilns, ladles, and chemical pipelines.
Why leading global distributors, brand owners, and system integrators choose Dianyang Technology as their preferred long-term manufacturing partner.
Operating out of Shenzhen—the world's capital for electro-optical hardware innovation—Dianyang Technology bridges the gap between state-of-the-art optical engineering and cost-optimized mass production. Our affiliation with listed parent company VHD provides financial stability, deep component purchasing power, and shared advanced testing facilities.
We maintain automated high-speed Surface Mount Technology (SMT) lines capable of mounting micro-pitch BGA components with sub-micron alignment accuracy. By performing mainboard processing, optics assembly, and shell molding in-house, we eliminate intermediate vendor markups and maintain total control over lead times.
Radiometric precision demands rigorous temperature calibration. Dianyang operates automated blackbody calibration rooms where every thermal camera undergoes multi-point curve fitting across extended ambient temperatures (-20°C to +60°C), ensuring NIST-traceable temperature accuracy of ±2°C or ±2% of reading.
Through long-term strategic relationships with premier uncooled microbolometer sensor foundries and Germanium lens manufacturers, Dianyang guarantees stable supply chains, insulated from global chip shortages, offering guaranteed production continuity for multi-year enterprise contracts.
