Three Integration Pathways — Ethernet, Modbus TCP, and 4–20 mA

The WIC Industrial’s automation integration capability is built around three complementary communication interfaces, each serving a different integration scenario. Ethernet PoE: transmits the full per-pixel radiometric image data stream at the camera’s frame rate over a single cable that also delivers power, enabling high-bandwidth integration with PC-based SCADA systems, machine vision platforms, and custom automation software via the Windows/Linux SDK. Modbus TCP: a standard industrial protocol layered over Ethernet, enabling direct register-level communication with PLCs — the camera exposes per-zone temperature values, alarm states, and camera status as Modbus registers that any Modbus-compatible PLC can read without requiring a PC or SDK. This is the most direct path to PLC integration for the standard industrial automation topology where a PLC is the primary control system and needs temperature alarm inputs from the thermal camera. 4–20 mA analog output: provides a single continuous analog current signal proportional to the temperature of a specified zone or pixel, compatible with any process control system (DCS, legacy PLCs, data loggers) that accepts the 4–20 mA standard — the universal language of process instrumentation that has connected field instruments to control systems for decades.

Closed-Loop Process Control with Per-Pixel Radiometric Data

In an automation context, the WIC Industrial’s per-pixel radiometric data enables several levels of process control integration. Alarm-based control: Modbus TCP registers or digital outputs signal a PLC when any pixel or zone in the image exceeds a temperature threshold, triggering process actions (conveyor stop, alarm, reject gate, process parameter change) without requiring a PC in the control loop. Zone-based analog feedback: the 4–20 mA output provides a continuous temperature signal from a defined zone for direct feedback to a PID controller or process setpoint system, enabling the thermal camera to act as a non-contact temperature transmitter within a standard process control loop. Full radiometric integration: the SDK-based Ethernet data stream provides the complete per-pixel temperature array to a PC-based control system, enabling advanced algorithms (temperature distribution pattern matching, gradient analysis, area-above-threshold computation) that determine process quality pass/fail decisions in automated inline inspection stations.

Radiometric Thermal Accuracy for Closed-Loop Process Control

Measures absolute temperature for every pixel, enabling detailed process analysis and control. Per-pixel radiometric data supports threshold alarm generation via Modbus TCP for PLC integration, continuous analog temperature feedback via 4–20 mA for PID process control loops, and full radiometric image analysis via SDK for advanced automated inspection algorithms — enabling the WIC Industrial to fit into any industrial control architecture from legacy analog systems to modern Industry 4.0 platforms.

Real-Time Monitoring with Remote Access

Provides live radiometric thermal imaging for continuous observation of industrial processes. Network connectivity via Ethernet enables remote access to the camera’s live thermal image, temperature data, and alarm state from any networked workstation, enabling remote monitoring of installed cameras in substations, process plants, and manufacturing facilities without requiring a local operator at each camera installation point.

PLC, SCADA, and Industry 4.0 Integration

Compatible with PLCs and SCADA systems via Modbus TCP and 4–20 mA outputs, and with Industry 4.0 platforms via the Ethernet SDK data stream. This multi-protocol integration capability allows the WIC Industrial to be deployed in both new greenfield Industry 4.0 smart factory installations and legacy brownfield facilities with established PLC/DCS control infrastructure, without requiring the control system to be replaced or upgraded to accommodate the thermal camera.

High Thermal Sensitivity — 30 mK NETD

Detects even subtle temperature variations of 0.03°C for early fault identification. In process control contexts, 30 mK sensitivity enables detection of process temperature deviations that are large enough to affect product quality but too small to trigger conventional temperature sensors or safety systems — enabling closed-loop correction before the deviation propagates to a quality rejection.

Interchangeable Germanium Optics for Application Flexibility

Wide-angle or telephoto Germanium lens options allow the same camera body to be configured for different monitoring scenarios without replacement: a wide-angle lens for covering large furnace chambers, conveyor sections, or substation switchgear bays; a telephoto lens for monitoring small weld puddles, electronic components, or distant process targets at long camera-to-target distances. This lens interchangeability protects the capital investment in the camera body across changing process monitoring requirements.
