Market guide
Choose the inspection workflow
Match the camera to building, electrical or mechanical workThe same thermal pattern can mean different things under different loads, environments and surfaces. Choose features around the inspection procedure and keep interpretation inside the operator's qualification.
01
Building
Favor low contrast, wide context and repeatability
Building work can depend on thermal sensitivity, wide coverage, environmental stability, moisture or pressure context and comparable level/span settings.
- Boundary
- A thermal image can indicate an anomaly; it does not prove hidden moisture, mold, insulation failure or a repair by itself.
- Reporting
- Keep visual context, location, weather, operating state and limitations with each image.
02
Electrical
Do not let non-contact imaging erase electrical risk
Inspection near exposed energized parts requires qualified-person boundaries, safe methods and appropriate protective equipment. A camera does not remove shock or arc hazards.
- Lens
- Choose a view that resolves the target from the approved position without unsafe approach.
- Load
- Retain equipment load, enclosure state and comparison basis because temperature without operating context can mislead.
03
Mechanical
Keep heat flow and operating state visible
Speed, load, lubrication, airflow, ambient temperature and nearby heat sources can change a mechanical pattern.
- Range
- High-temperature capability matters only when the target, lens and calibration range support the method.
- Trend
- Comparable routes and settings are usually more useful than one isolated image.
