The g-industrial-camera library from John Medland (Serenial) is a lightweight wrapper for industrial cameras (e.g. Basler GigE/USB) designed for simple integration into applications such as LabVIEW via DLL calls.

It provides a straightforward API for:

• Device enumeration
• Camera configuration (pixel format, trigger, etc.)
• Image acquisition (snapshot / streaming)
• Buffer handling

Important:

This driver allows camera access without requiring an NI Vision / IMAQdx license, which can significantly reduce system cost.

Image acquisition (snapshot/streaming) may timeout when running from a compiled EXE, while:

• The same code works in development (e.g. LabVIEW IDE)
• Vendor tools (e.g. Basler pylon Viewer) work correctly
• Camera enumeration and property queries succeed

Windows Firewall blocks the incoming GigE Vision UDP image stream for the application EXE.

Important details:

• Development tools (e.g. LabVIEW.exe) are often already whitelisted
• A compiled EXE is treated as a new application → blocked by default
• Control communication works, but streaming (UDP) is blocked
• Results in timeout errors during image acquisition

Allow the EXE in Windows Firewall:

• Windows Security → Firewall & network protection
• Allow an app through firewall
• Add the application EXE
• Enable:

  • Private networks
  • Public networks (important for camera NICs)

After this, acquisition works as expected.
