Explore our flagship thermal imaging systems engineered for maintenance, diagnostics, and OEM integration.
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 ODM/OEM services for infrared thermal imaging solutions, including handheld thermal imagers, smartphone-connected thermal cameras, thermal analyzers, and thermal imaging telescopes. Our products serve global customers in power inspection, building diagnostics, firefighting, industrial maintenance, and outdoor applications.
Our dedicated engineering team applies Design for Manufacturing (DFM), Design for Testability (DFT), thermal simulation, and EMC pre-compliance analysis to optimize performance and accelerate development. We also support clients in obtaining key certifications such as CE, FCC, RoHS, REACH, CB, UKCA, KC, and PSE.
Industrial B2B procurement of infrared thermography solutions has shifted from standalone devices to deeply integrated, software-defined thermal sensing ecosystems.
Enterprise buyers require robust cross-platform SDKs (Android, iOS, Windows, Linux) with real-time temperature telemetry streamed frame-by-frame. Our custom OEM modules provide raw radiometric data feeds directly compatible with proprietary industrial predictive maintenance platforms.
Achieving low Total Cost of Ownership (TCO) demands uncooled VOx (Vanadium Oxide) microbolometer arrays with zero defect pixel tolerance. Our automated semiconductor testing ensures long-term calibration stability across extreme operating gradients (-20°C to +550°C standard, up to +1200°C extended).
Leveraging Shenzhen Stock Exchange listed parent company VHD's capital backing, Dianyang eliminates supply chain bottlenecks. Procurement leaders secure long-term component lifecycle availability, volume price protection, and streamlined international customs clearance.
From power grid thermography to mobile diagnostic micro-hardware, our OEM thermal scanners deliver actionable thermal intelligence.
High-voltage transformers, switchgear, and overhead distribution lines are vulnerable to contact resistance overheating. Dianyang’s handheld (DP-38D, DP-25D) and module-based scanners enable rapid non-contact thermal mapping to catch phase imbalance and insulation degradation before catastrophic failure occurs.
Detect hidden moisture intrusion, thermal bridging, and structural insulation leaks. Dual-light cameras (DP-12DV, DP-25DV) blend visible detail with thermal radiation imagery, allowing building inspectors to map energy loss gradients and issue certified audit reports effortlessly.
Transforming smartphones into professional thermal analyzers. Our ultra-compact mobile series (H1FB, H2FB) plugs directly into Type-C/iOS devices, providing field service technicians with portable 256x192 or 160x120 thermal vision for instant troubleshooting in tight spaces.
Designed for operation through dense smoke and extreme heat ambient conditions. Thermal contrast enhancement algorithms allow first responders to locate human signatures and internal fire hot-spots rapidly while protecting thermal sensor electronics from thermal shock.
In electronic R&D labs, pinpointing sub-millimeter component overheating on populated printed circuit boards is critical. Our benchtop thermal analyzers and macro-lens attachments deliver high spatial resolution (IFOV) to prevent semiconductor thermal runaway.
Embedded thermal scanner cores integrated into automated robotic arms, security gantry platforms, and industrial conveyor belts for non-stop 24/7 automated temperature boundary monitoring and anomaly alarms.
Understanding the engineering metrics that dictate thermographic fidelity, measurement accuracy, and structural longevity.

Dianyang standardizes on Vanadium Oxide (VOx) uncooled microbolometers due to their superior Temperature Coefficient of Resistance (TCR) and lower noise floor compared to legacy a-Si sensors. VOx enables crisper thermal contrast and faster dynamic response, preventing image lag during rapid thermal scanning.
Our dual-camera models (DP-12DV, DP-25DV) extract optical edge outlines from a visible sensor and superimpose them directly onto the raw thermal radiation map in real-time. This spatial fusion allows technicians to read printed serial numbers and identify component labels while assessing temperature profiles.
Operating under rigorous corporate governance, every Dianyang thermal imager passes rigorous reliability protocols before global export.
Our engineers implement stringent DFM and DFT rules during the schematic design phase. Thermal dissipation simulations and stress testing ensure structural resilience against drop impacts, vibration, and thermal cycle fatigue.
Equipped with internal EMC testing laboratories, Dianyang shields sensitive infrared detector circuits against high-frequency electromagnetic interference commonly found around transformer substations and heavy motor drives.
We provide seamless market entry support for overseas distributors and OEMs. Certified compliant with CE, FCC, RoHS, REACH, CB, UKCA, KC, and PSE standards, ensuring frictionless clearance across North America, Europe, Asia-Pacific, and Latin America.

As a subsidiary of VHD (Shenzhen Stock Exchange listed), Dianyang benefits from publicly listed corporate backing. This ensures financial stability, rigorous ISO-certified quality management, continuous multi-million dollar R&D investments, and access to state-of-the-art SMT production platforms—delivering superior batch-to-batch repeatability and sensor calibration accuracy.
Our standard handheld series (such as the DP-12D, DP-25D, and DP-25DV) cover a temperature measurement spectrum from -20°C to +550°C with an accuracy of ±2°C or ±2% of reading. For specialized industrial high-temperature applications, models like the DP-38D extend measurement parameters up to +1200°C.
Yes. Our mobile imager series (H1FB, H2FB) comes with comprehensive software development kits (SDKs) for both Android and iOS. We support customized mobile app UI/UX, proprietary palette integration, automated thermal boundary alerts, and localized language translations for white-label brand partners.
We actively support our global partners by maintaining full international compliance. Our products are engineered and tested to acquire CE, FCC, RoHS, REACH, CB, UKCA, KC (Korea), and PSE (Japan) certifications, ensuring frictionless import and commercial distribution across major global markets.
Dual-light technology combines a visible light camera sensor with an uncooled infrared thermal detector. By blending structural visual edges over the thermal heatmap (DIF technology), technicians can instantly identify components, label tags, and pin locations without losing critical temperature gradient insight.
Standard white-label logo branding orders typically start at low MOQs (50–100 units). Full custom tooling, custom PCB re-engineering, or unique housing molds require custom project evaluation. Lead times range from 2 weeks for standard customized production to 6–8 weeks for full hardware ODM projects.
