GigE Thermal Imaging Camera Module

GigE Vision Protocol — The Machine Vision Standard

GigE Vision is an industry standard interface specification (published by the Automated Imaging Association, AIA) that defines how machine vision cameras communicate with host computers over Gigabit Ethernet. It specifies: GenICam (Generic Interface for Cameras) device configuration for standardised camera parameter access; GVSP (GigE Vision Stream Protocol) for efficient uncompressed image data transfer; GVCP (GigE Vision Control Protocol) for camera control commands; and hardware trigger support for precise image capture synchronisation with external events (PLC outputs, encoder pulses, proximity sensor signals). These capabilities make GigE Vision the preferred interface for industrial machine vision applications where frame synchronisation with the production line, uncompressed pixel data for image processing algorithms, and standardised integration with machine vision software are required.

GigE Vision vs ONVIF/RTSP — When to Choose Each

The key distinction is application domain. ONVIF/MJPEG/RTSP (the Ethernet thermal module) is designed for the security and surveillance domain: VMS/NVR interoperability, compressed video streaming over LAN/WAN, remote monitoring, and human-operator viewing. GigE Vision (this module) is designed for the industrial machine vision domain: uncompressed image data for algorithmic analysis, hardware trigger synchronisation with production equipment, GenICam standardised parameter control, and integration with machine vision software platforms. Both use Gigabit Ethernet, but the protocols serve fundamentally different integration architectures. Choose ONVIF/RTSP for security and surveillance VMS integration; choose GigE Vision for industrial machine vision, automated inspection, and production-line integration.

GigE Vision High-Speed Machine Vision Interface

GigE Vision protocol provides uncompressed thermal image streaming with GenICam standardised camera control and hardware trigger support — the interface capabilities required for industrial machine vision: precise frame synchronisation with production equipment, uncompressed pixel data for analytical algorithms, and standardised integration with machine vision software platforms.

High Thermal Resolution and <50 mK Sensitivity

640 × 480 px LWIR detection at <50 mK provides the spatial detail and thermal sensitivity required for industrial defect detection, temperature threshold inspection, and process monitoring at machine vision working distances.

60 Hz High Frame Rate for Production Line Inspection

60 Hz thermal frame rate enables adequate temporal sampling of fast-moving production line components for high-speed thermal inspection applications where 30 Hz would introduce motion blur or missed thermal features between frames.

Advanced On-Board Processing

On-board gain control, spatial and temporal noise filtering, and colour palette application deliver processed thermal images over GigE Vision, reducing the inspection system’s host processor load for sensor-level signal conditioning.

Compact <85 g for Machine Vision System Integration

Compact ~40×38×45 mm dimensions and under 85 g weight enable integration into machine vision enclosures, inspection stations, and OEM equipment where space and weight are constrained alongside other sensors and optics.

PoE for Distributed Inspection Network Simplicity

PoE power delivery over the GigE Ethernet cable simplifies installation at distributed inspection stations and remote monitoring points where routing a separate power cable alongside the GigE data cable would add wiring complexity.
