What is a GigE Vision Camera?
GigE Vision is an industrial camera interface standard that uses standard Gigabit Ethernet hardware to transmit high-resolution image data from cameras to computers or edge processors. Standardised by the Automated Imaging Association (AIA), GigE Vision cameras work with a wide range of machine vision software and can transmit data over cable runs up to 100 metres without signal degradation — far longer than USB or Camera Link connections.
For factory automation and AI visual inspection applications, GigE Vision has become the dominant interface choice because it uses infrastructure that most factories already have: standard Cat5e or Cat6 Ethernet cabling, standard network switches, and standard RJ45 connectors. This dramatically reduces installation cost and complexity compared to proprietary interfaces.
Key Specifications to Evaluate
Resolution
Resolution determines the smallest defect your system can reliably detect. For most surface inspection applications, 2MP to 5MP provides the right balance of detail and processing speed. High-precision applications — such as semiconductor inspection or fine print verification — may require 12MP to 20MP. Indus Vision’s GigE camera range covers 0.4MP through 20MP using Sony IMX sensors, which set the industry benchmark for sensitivity and noise performance.
Frame Rate
Frame rate determines how many images per second the camera can capture. For most conveyor-based inspection, 30fps to 60fps is sufficient. High-speed packaging lines, automotive stamping, and beverage filling lines may require 100fps or higher. Indus Vision GigE cameras deliver from 8fps for detailed static inspection up to 160fps for fast-moving production lines.
Sensor Type: Area Scan vs Line Scan
Area scan cameras capture a complete rectangular image in a single exposure — ideal for inspecting discrete parts, labels, and assembly components. Line scan cameras capture one line of pixels at a time, building up an image as the product moves past. Line scan is the correct choice for continuous web materials such as film, foil, fabric, paper, and sheet metal, where the product has no defined length. Indus Vision line scan models run at 200kHz line rate with resolutions from 2k to 8k pixels — covering even the widest web applications.
SWIR Cameras for Specialist Applications
Short-Wave Infrared (SWIR) cameras capture light in the 900-1700nm wavelength range, invisible to standard visible-light cameras. SWIR imaging is the correct choice when you need to detect moisture content (useful in food and pharmaceutical inspection), sort materials by composition, inspect through certain packaging materials, or detect features that lack visible contrast. Indus Vision’s SWIR range gives Indian manufacturers access to this previously expensive technology at accessible price points.
Triggering and Synchronisation
Reliable triggering is critical for consistent inspection. GigE Vision cameras support three triggering modes. Software triggering sends a command over the network — suitable for slow lines and testing but introducing network latency. Hardware triggering uses a direct electrical signal from a sensor or encoder, delivering microsecond-accurate timing essential for fast production lines. Encoder triggering synchronises capture to the physical position of the product, ensuring every image is taken at exactly the same position regardless of line speed variation.
For multi-camera setups that need synchronised exposure across all cameras simultaneously, Indus Vision cameras support precision time protocol (PTP) synchronisation over the GigE network.
Software Compatibility
All Indus Vision GigE cameras are compatible with industry-standard machine vision software through the GigE Vision protocol. This includes Cognex VisionPro, Halcon, NI Vision (LabVIEW), MATLAB Image Acquisition Toolbox, and OpenCV. They are also directly supported by DeepVision, Indus Vision’s AI inspection platform, which uses them as its primary imaging hardware. This means you can use the same camera hardware for both traditional rule-based inspection and AI-powered defect detection.
