// Features

Professional-grade tools for your bench

Built for electronics engineers who need accurate, actionable thermal data — not consumer gimmicks.

Live Thermal View

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.

Accurate Temperature Readout

Pixel-accurate temperature measurement at cursor position. Uses proper raw sensor conversion (raw ÷ 64 − 273.15 °C) for scientifically meaningful readouts you can trust.

Multi-Camera Support

Works natively with InfiRay A1T (UVC) and Thermal Master P3 (vendor protocol), with more cameras being added. Plug in your hardware and HotSpotter handles the driver details.

// The Platform

Built for the lab bench

Precision linear motion, active thermal stabilisation, and a rigid aluminium extrusion frame — the HotSpotter hardware platform delivers repeatable, calibrated scans every time.

Integrated power & control

Built-in dual-readout temperature controller and mains power supply. Levelling feet and a low centre of gravity keep the platform rock-solid on any bench.
