Spotting an overheating breaker, a loose lug, or a failing motor bearing before it fails outright is exactly what thermal imaging is for — and you genuinely don’t need a $2,000+ professional camera to catch the obvious hot spots that matter most on routine inspections.
What to Look For
A basic smartphone thermal attachment is enough for spotting an obvious hot connection or panel issue. If you’re doing inspections regularly, genuine improvements in resolution, field of view, and image enhancement from a more established brand pay for themselves in what you can actually diagnose.
