// Thermal PCB Inspection
HotSpotter turns your USB thermal camera into a professional PCB inspection tool. Calibrated temperature readings, real-time thermal imaging, and multi-camera support — all in a clean Windows desktop app.
// Features
Built for electronics engineers who need accurate, actionable thermal data — not consumer gimmicks.
Real-time calibrated thermal imaging from your USB camera. Full-frame streaming with configurable color palettes to reveal temperature gradients the moment you point the camera.
Pixel-accurate temperature measurement at cursor position. Uses proper raw sensor conversion (raw ÷ 64 − 273.15 °C) for scientifically meaningful readouts you can trust.
Works natively with InfiRay A1T, Topdon HT-301 (UVC) and Thermal Master P3 (vendor protocol), with more cameras being added. Plug in your hardware and HotSpotter handles the driver details.
NUC (Non-Uniformity Correction) support for consistent flat-field thermal accuracy. Per-camera lens configuration presets with user-editable profiles stored locally.
