HeatDeck

Thermal image analysis · Mac and Windows · works offline

Open thermal images from any camera brand, on Mac or Windows.

Read temperatures from FLIR and InfiRay / Topdon files in one app, measure spots, boxes and lines, and export a branded inspection report in one click. DJI, HIKMICRO and Fluke files are next in line.

Radiometric JPEG and .irg in · TIFF, CSV and PDF out · files never leave your computer

The HeatDeck window: an ironbow thermal image of an electrical panel with one breaker glowing yellow, a crosshair cursor reading 71.4 °C over it, a box measurement showing min 28.9, max 71.4 and average 41.2 °C, a palette scale from 24 to 75 °C, and the emissivity, reflected temperature and distance settings in a side panel.

One camera brand, one app. Three brands, three apps and a Windows PC.

  • Each brand's software opens only its own files, so a team with mixed cameras runs three or four apps to write one report.
  • Vendor tools run on Windows only. FLIR's old Mac app is discontinued, and DJI's thermal analysis tool does not run on Mac.
  • FLIR Thermal Studio costs $216–432 a year, for one brand's files.
  • Clients who receive your thermal JPEGs see a picture, not a temperature, unless they install the vendor's software too.

How it works

Drop in a folder. Read every pixel's temperature.

1

Drag in a folder of mixed-brand images

HeatDeck reads the radiometric data inside each file, whichever camera took it, and lays the batch out as thumbnails with the visual photo beside each thermal one.

2

Measure and correct

Hover for the temperature under the cursor. Draw spots, boxes and lines for min, max and average. Set emissivity, reflected temperature and distance per image or for the whole batch, and every reading updates.

3

Export the report

Lock one palette and temperature range across the batch so images compare fairly, then export a PDF inspection report with your logo and notes, or radiometric TIFF and CSV for further analysis.

Temperature under the cursor

Live readout as you move, plus spot, box and line tools with min, max and average.

One palette across a batch

Lock palette and span so a hot spot looks equally hot in every image of the report.

Emissivity, reflected temperature, distance

Change the object parameters after the fact and the temperatures are recomputed from the raw data.

Batch export

Radiometric TIFF and CSV for every image in one go, for Excel, Python or GIS.

One-click PDF report

Your logo, the thermal and visual images side by side, measurements in a table, your notes.

Offline by design

Everything runs on your computer. No account is needed to open a file, and no image is uploaded.

Formats

The files HeatDeck opens

Radiometric files carry a temperature for every pixel. HeatDeck reads that data directly, not the coloured picture.

Supported

FLIR radiometric JPEG

The .jpg files saved by FLIR handheld cameras and many OEM cores, with the raw sensor data and calibration stored inside.

Supported

InfiRay / Topdon .irg

Radiometric captures from InfiRay-based cameras, including Topdon models.

Coming soon

DJI R-JPEG

Radiometric JPEGs from DJI drone cameras such as the M3T, M30T and H20T.

Coming soon

HIKMICRO

Radiometric images from HIKMICRO handheld cameras.

Coming soon

Fluke .is2

Fluke's thermal image format, with the visible-light image and annotations.

Your client's building stays on your computer

Thermal images show the inside of people's homes, plants and switchrooms. HeatDeck processes every file on your own machine: nothing is uploaded, nothing needs an account to open, and it works on a roof with no signal. Reports are written to your disk and go only where you send them.

Thermal imaging guides

Open a FLIR image on Mac

Preview shows a FLIR JPEG as a picture. Reading temperatures on a Mac needs the radiometric data inside it. What the file holds and how to open it.

FLIR Tools for Mac

FLIR's Mac app is discontinued and Thermal Studio is Windows-only. What FLIR Tools did, what Mac users can use instead, and how to keep your workflow.

FLIR Thermal Studio alternative

Thermal Studio is Windows-only, FLIR-only and $216–432 a year. A comparison of the alternatives for inspectors who need Mac support or mixed camera brands.

DJI thermal images on Mac

DJI's thermal analysis tool doesn't run on macOS. How R-JPEG files store temperatures, the Mac workarounds today, and where HeatDeck's DJI support stands.

HIKMICRO files on Mac

HIKMICRO's desktop analysis software is Windows-only. What Mac users can do with HIKMICRO thermal images now, and when HeatDeck will open them.

Convert DJI R-JPEG to TIFF

Why you'd convert R-JPEG to TIFF, what a radiometric TIFF contains, how to do it with DJI's Thermal SDK today, and HeatDeck's batch export.

Read temperature from a thermal image

Thermal image colours aren't temperatures. How radiometric data becomes a reading, what emissivity and reflected temperature do, and mistakes to avoid.

Thermal inspection report template

A practical thermal inspection report template for electrical and building surveys: the fields clients need, how to show images, and severity by delta-T.

Questions inspectors ask

Can I open a FLIR image on a Mac?

Yes. HeatDeck runs natively on macOS and opens FLIR radiometric JPEGs with full temperature data: the reading under the cursor, spot, box and line measurements, and emissivity correction. You don't need Boot Camp, a virtual machine or a Windows PC.

Is there a FLIR Tools for Mac?

FLIR's Mac app is discontinued, and FLIR Thermal Studio runs on Windows only. HeatDeck covers the everyday FLIR Tools jobs on a Mac: reading temperatures, adjusting parameters, setting palettes and writing a report.

Is HeatDeck an alternative to FLIR Thermal Studio?

For opening, measuring and reporting, yes, and it also reads InfiRay / Topdon files in the same batch. It costs $149 a year against $216–432 for Thermal Studio, and it runs on Mac as well as Windows.

Can I analyse DJI thermal images on a Mac?

DJI R-JPEG support (M3T, M30T, H20T) is in progress and is marked as coming soon. Today HeatDeck opens FLIR radiometric JPEG and InfiRay / Topdon .irg files.

Does it open HIKMICRO files?

HIKMICRO support is coming soon. When it ships, HIKMICRO images will open in the same batch as your other cameras.

Can I convert thermal images to TIFF or CSV?

Yes. Pro exports a whole batch to radiometric TIFF (one temperature value per pixel) and CSV in one step. R-JPEG to TIFF follows once DJI support is out.

Do you have a thermal inspection report template?

HeatDeck's PDF report is the template: your logo, the thermal and visual images side by side, measurement tables, object parameters and your notes, laid out automatically for every image you select.

Are my images uploaded anywhere?

No. Every file is read and processed on your computer. HeatDeck works fully offline.

Can I use HeatDeck for fever screening or medical work?

No. HeatDeck is built for building, electrical, mechanical and solar inspection. It is not a medical device.
