Reporting methods shape the final deliverable
For a client or maintenance manager, the report is the lasting product of an inspection: the record they consult when making decisions. Its quality depends on technical judgment, but also on how images, measurement settings and conclusions reach the document. The reporting method affects consistency, traceability and the effort needed to correct information after review.
Camera manufacturer software, Word or Excel templates and dedicated reporting software can each suit different needs. There is no universally best option. A team using one camera for occasional reports faces different challenges from an operation with several camera brands, multiple thermographers and recurring inspections of the same assets.
Compare methods against your camera fleet, reporting volume, review arrangements and need for historical records. This article focuses on choosing a production method. Route planning and the workflow from field capture to PDF, covered in earlier blog articles, provide background rather than the structure for this comparison.
What every method needs to deliver
Apply the same requirements to every alternative. A polished document may conceal missing information, while a complete record can still be difficult to review if its evidence is scattered. Assess both the delivered PDF and the supporting records needed to reconstruct the analysis.
- Preserved evidence: the original radiometric file available for reanalysis, the reported thermal image and the corresponding visual image of the same inspection point.
- Settings and operation: adopted emissivity, reflected apparent temperature, ambient temperature and load condition at the time of inspection, with the source of the information.
- Identification: equipment tag, location, inspection point, capture date and time, thermographer, and camera model and serial number.
- Thermal comparison: anomalous point temperature, reference temperature and ΔT, with an explicit comparison basis.
- Assessment: severity criteria, their source and applicable edition, and a justified recommendation and priority.
This is a practical comparison checklist, not a transcription of requirements from a single standard. For example, ANSI/NETA MTS includes Table 100.18, "Thermographic Survey — Suggested Actions Based on Temperature Rise". If that is the adopted criterion, document the edition and comparison basis: similar components under similar loading, or a component compared with ambient air. The method must retain that distinction rather than just a severity color.
ABNT NBR 15572:2013 provides guidance for thermographic inspection of electrical and mechanical equipment. ABNT NBR documents are Brazilian standards; outside Brazil, follow the criteria adopted in the contract and the relevant country. Software selection does not establish the technical procedure or contractual criteria. It must also keep reflected apparent temperature distinct from ambient temperature.
Camera manufacturer software
A typical strength is close support for the camera's original format. In many cases, manufacturer software reads its own brand's radiometric files natively, allows measurement settings to be reviewed and provides report templates. For a fleet from one manufacturer, this can keep analysis and reporting closely aligned with the files captured in the field.
Check which camera models, formats and versions your software accepts, which parameters can be revised and how the results appear in a report. A ready-made template does not necessarily include every field required by your contract. Load information, adopted criteria and recommendations may need supplementary entry or template customization.
Rework tends to emerge with mixed-brand fleets. Each application may focus on its own file format, requiring separate analysis and exports to bring findings together. Page layouts, field names and the arrangement of information can differ. The team then needs a way to produce a consistent deliverable across those separate sources.
Historical records deserve attention too. If each inspection sits in a separate project or folder, finding the same point from a previous visit depends on file organization. That does not rule out the method, but it calls for common identification, storage and review practices. Assess those requirements with the people who will actually perform the work.
Word or Excel templates
Flexibility is the main attraction. Teams can tailor presentation to the client, add explanations and use familiar tools. A well maintained template may suit a limited reporting volume, a variable scope and a team with disciplined data entry and checking practices.
That freedom also places controls in people's hands. Copying temperatures and settings between applications creates opportunities for typing errors, misplaced decimal separators and values pasted into the wrong row. An image exported solely as a picture does not retain radiometric data for reanalysis. The reviewer must return to the original file, which needs to remain stored and associated with the inspection point.
Manual ΔT calculations require checking the source values and the direction of the comparison. Even a spreadsheet with formulas needs checks on cell references, inserted rows and template changes. Having a formula does not establish that the selected reference component is technically appropriate.
Different template versions can lead to missing fields, outdated criteria or inconsistent presentation across thermographers. Review becomes more laborious when each finding requires opening separate supporting files. A folder-based history can work, but it depends on consistent naming, version control and someone taking responsibility for the official template.
Dedicated reporting software
Start the evaluation with a demonstration using actual files from your operation. Verify which formats and cameras from different manufacturers are supported. Displaying a picture is different from preserving radiometric data and metadata for reanalysis. Ask how the original files are stored and how they can be retrieved later.
Check whether required fields are standardized and whether missing information is clearly distinguishable from completed records. Examine the link between inspection point and equipment, access to previous inspections and documentation of severity criteria. Assisted classification still requires the thermographer's review; responsibility for the technical assessment remains with that professional.
Review a sample PDF against your contract: branding, image readability, findings organization and room to explain limitations. Standardization is useful when it preserves the necessary context. An overly rigid form may push important information into separate documents, recreating the reconciliation work the team wanted to avoid.
Consider adoption effort, cost and dependence on the supplier as well. Ask about training, template maintenance, record access and export options if you stop using the product. These belong in the comparison alongside technical capabilities. A team trial can show whether effort has decreased or simply moved to another part of the process.
Where rework and errors arise
Copying and pasting information
The risk is transferring a value without its source. With any method, ask a reviewer to reconstruct a finding using the report and original file. If the author must explain where the reference came from, traceability is incomplete. Look for a routine that keeps values, settings and identification together, even where some entry remains manual.
Assigning images to the wrong point
Similar components can produce convincing pages containing the wrong image. Examine how each alternative associates the thermal image, visual image and point identifier. File names and capture sequence help, but review must confirm the match with the equipment. Also test what happens to that association when an image is replaced during preparation.
Handling a mixed-brand fleet
Include representative files from every camera in the evaluation. Follow their path through to the document, including intermediate exports. A tool may serve most of the fleet well while requiring separate handling for certain files. Identifying that exception before selection lets the team assess its effect on everyday reporting work.
Maintaining consistency across thermographers
Compare documents prepared by different people against the same requirements. Consistency should cover fields, identification, the source of assessment criteria and recorded limitations, as well as appearance. Assign responsibility for approving template changes and distributing them. Required fields can prompt people to capture information, but they cannot establish the quality of what is entered.
Keeping history across inspections
Retrieve an older point using the equipment identifier without relying on the author's memory. Then check whether load, reference and measurement settings remain available to interpret changes. Useful history preserves context: temperatures from different visits are not automatically comparable. Also examine how later corrections retain the identity of the report that was originally issued.
Questions to guide your choice
- Are original radiometric files preserved, easy to locate and available for reanalysis?
- Does the method accommodate every camera and file format used by the team?
- Do thermal and visual images stay associated with the correct point?
- Are required fields enforced, or does completion depend on individual discipline?
- Are severity criteria, their source, edition and comparison basis recorded?
- Can the same point be retrieved across inspections with its load condition?
- How much review time does each report need, and which corrections keep recurring?
- Who maintains the template and communicates changes to thermographers?
- Does the PDF meet the contract without additional assembly in another application?
- How will the team access originals and history after changing methods or suppliers?
Use these questions in a trial with a representative set of findings, including missing information and a correction requested by the reviewer. Note where data must be entered again, files located manually or identification clarified. Compare preparation, review and later retrieval effort, alongside the ease of producing the first page.
Where ThermalReports fits
ThermalReports runs in the browser and supports importing radiometric images and JPEG files directly from cameras made by different manufacturers, preserving metadata and palettes. It provides assisted anomaly classification with recorded criteria, links inspection points to equipment and standards, and produces standardized PDFs with branding, images and a findings table. Equipment QR codes provide inspection history. The thermographer reviews the assessment and retains technical responsibility. Check compatibility with files from your own fleet when evaluating the platform.
Choose against the work your team actually does
The best fit depends on how your team preserves evidence, reviews conclusions and retrieves previous records. Flexibility, camera compatibility and report organization carry different weight in different operations. Compare alternatives against the same requirements and identify where each needs additional controls.
