160 × 120 pixels.Recommended minimum for building inspection

We recommend at least 160 × 120 pixels for building work. For moisture work, go to 240 × 180 or above.

A thermal camera shows how a building is really performing: missing insulation, air leaks, hidden moisture and heating faults, all without opening a wall.

Problems found early can be documented and fixed before they become expensive repairs. Building work often means reading small temperature differences, so a camera with good sensitivity matters, and so does knowing how materials, emissivity and reflected heat affect what you see. That’s what our free training covers.

Missing insulation

Missing or poorly fitted insulation shows up as cool patches on ceilings, walls and roofs in winter, and warm patches in summer. A thermal image shows the whole surface at once, so you see how big the gap is as well as where it is.

The same walk-through shows the condition of HVAC systems and electrical faults. Scan when there’s a good temperature difference between inside and outside for the clearest result.

Air leaks

Gaps around doors, windows, vents and downlights let conditioned air out and outside air in. On a thermal image they show as streaks of cold or warm air spreading from the gap.

Find them before sealing, then scan again to check the fix worked.

Moisture and hidden leaks

A thermal camera can’t see water, but it shows the cool patterns that wet materials leave behind. A moisture meter then confirms the area is wet and not just cold.

The E6 Pro meets it. The MR277’s built-in imager is 160 × 120, so for regular moisture work pair a meter with a camera.

Use the two together: the camera finds the suspect area fast, and the meter gives you the reading for your report.

Underfloor heating

A thermal camera shows underfloor heating pipes and cables that are normally hidden, so you can check the system heats evenly, find a cold loop, or map the pipes before a renovation.

Marking out the pipe runs first means nobody drills or cuts into a heating loop.
