The practical answer

Choose M4T for a portable thermal workflow, M4E for visible asset records, or M400 with H30T when the specified payload and a larger team deployment fit the inspection plan. Start with the component, evidence and engineering decision.

Start with the maintenance question

A procurement brief becomes clearer when it names the decision: whether a pipe support needs closer examination, whether a component should join a maintenance worklist, or whether a tower inventory needs updating. Each requires different photographs and different professional follow-up. Asking for a general site inspection leaves too much for the pilot to infer.

Collect the asset register, a marked plan, previous findings and the name of the person who will accept the evidence. Agree which surfaces must be seen and what makes an image useful. A reviewer may need a readable identification plate, a complete connection or a matched view from a previous visit rather than the widest possible panorama.

Portable thermal observations: IN-01 and IN-04

IN-01 combines M4T, five flight batteries in total, Terra Flagship for one year, a charging hub, a WB37 controller battery and its USB-C charging hub. Training and support accompany the equipment. IN-04 adds DJI Power 2000 to that configuration.

Use this route when the brief calls for visible context and thermal observations from a portable team kit. Ask the intended reviewer to approve a small example dataset before deciding the capture schedule. A neat thermal picture is useful when the target, conditions and original file can be recovered later.

Larger deployment: IN-02 and IN-05

IN-02 supplies M400 with H30T, three TB100 flight batteries in total, BS100 charging station, two WB37 batteries and a one-year Terra Flagship licence. IN-05 adds Power 2000. The three-battery total matters when comparing this industrial configuration with other M400 packages.

The larger platform deserves consideration where the payload, mobilisation plan and team responsibilities are a good fit. Compare the route geometry, transport, charging location and achievable evidence before treating aircraft size as the deciding factor. An awkwardly positioned component can remain unobserved with either platform; the capture plan should identify that gap honestly.

Visible asset and tower records: IN-03 and IN-06

IN-03 uses M4E with five flight batteries in total, controller battery and charging accessories. Its included one-year Terra Standard licence is restricted to M4E/M4D data. IN-06 adds Power 2000. This is the visible-record route within the approved industrial range.

A tower inventory, pipework overview and thermal maintenance observation should have different acceptance examples. For visible work, agree the required component detail, image orientation and naming. For a measured deliverable, commission the measurement method and checks explicitly rather than relying on the appearance of a three-dimensional model.

Make site controls part of the purchase brief

HSA guidance treats permits as a way to authorise, communicate and control work. [1] Ask the site coordinator to explain how the flight joins that system, who releases each work area and who can stop the task when plant or people move.

Describe cranes, vents, traffic, nearby conductors and changing production activities before mobilisation. Where the site identifies an explosive-atmosphere zone, obtain a specific equipment and work-method decision from the responsible specialist. A general industrial package is not an ATEX approval. [2]

Specify a handover that survives staff changes

Require one row per observation with an asset identifier, location, capture date, file reference, visible context and review status. Separate what the image shows from what an engineer concludes. An image can be accepted as a record while the maintenance decision remains open.

Ask for an exception list covering obscured, inaccessible and incomplete items. Give each exception an owner and a next action. This turns partial coverage into a manageable worklist instead of leaving the maintenance team to discover omissions while opening folders. Agree who stores originals and how the next inspection will refer back to them.

Run a small acceptance trial

Select representative assets: one easy target, one reflective or visually complex target and one difficult viewpoint. Ask the team to capture, index and review those examples through the proposed workflow. Evaluate the result on a normal office computer with the person who will use it.

Record the reasons an example passes or needs recapture. Those reasons might be identification, focus, viewing angle, relevant operating context or missing companion photographs. Use the trial to refine training and the deliverable specification. It is a procurement acceptance exercise; the site-specific risk assessment and engineering procedure remain the responsibility of the appointed specialists.

Make the example dataset part of the agreement

For example, a buyer comparing two thermal platforms can ask each proposed workflow to identify the same representative asset, retain the original observation and populate the agreed register. The useful comparison is whether the receiving engineer can find and review that evidence.

Record the outcome as a purchasing decision: accepted example, required improvement or different method needed. Keep that decision with the training plan and equipment quotation, so the initial conversation remains understandable when the team receives the kit.

Questions to settle before ordering

Is Terra a maintenance diagnosis service? The included licence is a processing tool; agree the intended outputs and responsible reviewer separately. Is the Power version a different sensor package? It adds portable power to the corresponding core kit. Choose it around the charging plan.

Send Irish Drone the asset types, representative photographs, required file handover, site restrictions and intended team size. Compare the three equipment routes against that brief, then use the narrower guides for equipment thermography, tower records or facility campaigns.
