Thermal Phone Samples: A Frame-Rate Acceptance Checklist

For a factory sample offered against a fast-response or 60Hz thermal-phone requirement, agree on an acceptance procedure before ordering. Test the quoted configuration and document the result; a smooth-looking demonstration alone does not establish the rate of new thermal images.

Define what the test must answer

Write down whether you need thermal image updates during motion, a live inspection view, recorded video or another output. Define the required rate and how it will be verified. Keep camera response, displayed video and saved-file behavior as separate questions.

Prepare an identifiable sample

• Record the handset serial number or sample identifier, thermal module, firmware and app version.
• Write down the recording mode and any settings that could affect the output.
• Agree on the target movement, camera movement, lighting-independent thermal scene and test duration.
• Keep an original recording or output file alongside the test notes.

Watch for evidence gaps

A saved file's nominal video rate does not by itself establish that every frame contains a new thermal image. Ask how the supplier distinguishes new thermal frames from repeated images. If the available output cannot answer the agreed requirement, request a suitable test method or mark the result unverified.

Use a clear acceptance record

For each requirement, record the method, observed result, supporting file and decision: passed, failed or unverified. A missing test should stay unverified. Agree on any retest after a module, firmware or application change rather than transferring approval automatically to a different configuration.

Keep sample approval distinct from production inspection

Ask which checks will be repeated on production units and what records will accompany the shipment. Specify responsibilities in the order documents. This is a suggested buyer process; it is not evidence that a particular factory performs these checks or that any Phonemax model delivers 60Hz thermal images.

Use the frame-rate guide to clarify the terminology and the manufacturer evidence checklist to request the configuration records. Current products are listed in the thermal imaging phone range.
