The real question is not whether your team can do it.
Many maintenance and facility teams eventually ask the same question: should we keep calling vendors for every inspection, or should we build the capability in-house?
It is a good question. Vendor dependency can be expensive, slow, and frustrating when the same checks keep repeating. But the answer is not simply "buy the camera" or "send one person for training." The better question is this:
What can your team do safely, repeatedly, and usefully - and what still needs specialist judgement?
Some work should move closer to the team.
In-house capability is strongest when it improves the daily quality of observation. Your team sees the equipment more often than any external provider. They know what changed, what sounds different, what is newly loaded, and what keeps coming back after a repair.
That context is valuable. Training should help the team capture it better.
Routine observation
Visual inspection discipline, asset condition notes, photos, and early warning signs that should not wait for the next vendor visit.
Pre-inspection preparation
Asset lists, access planning, operating condition, load context, previous issues, and the question the inspection needs to answer.
Basic image capture
Controlled thermal image collection can be trained, especially for repeat checks and internal screening, as long as safety and method limits are clear.
Better vendor conversations
A more capable internal team can brief specialists better, question weak findings, and understand why a method is or is not suitable.
But not everything should become in-house work.
The risk appears when teams confuse observation with interpretation. Seeing a hot spot is one thing. Deciding severity, root cause, urgency, and acceptable corrective action is another. A tool can capture a signal, but judgement still has to be earned.
Formal severity interpretation
Critical findings should be assessed by people who understand method limits, electrical context, and what the evidence can actually prove.
MV/HV testing decisions
High-risk systems need competent personnel, safe procedures, and clear authority. Training should not blur those boundaries.
Compliance-grade reporting
Reports used for audit, claims, management approval, or formal maintenance decisions need stronger review and defensible structure.
Professional sign-off
Where endorsement or specialist accountability is required, internal screening cannot replace proper review.
The best model is usually hybrid.
The goal is not to replace every vendor. The goal is to stop being blind between vendor visits. A capable internal team can observe earlier, prepare better scopes, collect cleaner context, and escalate the right cases to specialists.
That hybrid model is often stronger than either extreme. The team owns the routine discipline. Specialists handle high-risk interpretation, formal reporting, and cases where the evidence is incomplete or the consequence is serious.
Buying equipment is not the same as building capability.
A thermal camera can make problems visible. It cannot decide whether the image was captured under the right condition, whether the comparison is fair, whether the load was meaningful, or whether the recommendation is proportionate.
Equipment without method creates confidence faster than judgement. That is the danger. The team may feel more capable because the tool produces an image, but the decision still depends on how that image is captured, compared, interpreted, and acted on.
A simple way to draw the boundary.
Before moving inspection work in-house, separate the work into three layers:
Can the team observe it?
Can they safely recognise, document, and communicate the condition without overstepping the method?
Can the team interpret it?
Can they explain what the signal means, what else could cause it, and what cannot be concluded?
Can the team sign off on it?
Can they take responsibility for the decision, report, recommendation, or compliance implication?
Many teams can be trained to observe well. Fewer should interpret critical findings alone. Fewer still should sign off without specialist review.
AMKA's view
Bring the repeatable and low-risk work closer to the people who see the assets every day. Keep high-risk diagnosis, formal reporting, and specialist review properly controlled. The right training does not remove the need for experts; it helps your team know when expert judgement is actually needed.
