How do I choose an inspection camera or borescope?
An inspection camera or borescope carries a small camera and LED light on a flexible or rigid probe into hard-to-reach areas - bores, pipes, machines and assemblies. Key factors are probe diameter and length, resolution, articulation, display and waterproof rating. This guide sorts the criteria.
View inspection camerasWhat is an inspection camera used for?
An inspection camera - also called an endoscope or borescope - guides a small camera with LED light on a flexible or rigid probe into tight, dark or hard-to-reach spaces. You inspect bores, pipes, cavities, engines and assembled parts non-destructively, without taking them apart.
Flexible probes follow bends in pipes and ducts, while rigid probes give a stable image in straight bores. The live view appears on an integrated display or, via cable or Wi-Fi, on your smartphone.
Which selection criteria matter most?
Choose first by access and geometry: probe diameter and length must fit the opening and depth. Then weigh resolution, articulation, display type, waterproof rating and illumination. The table below summarises the criteria.
- Measure the opening and bend radius on the part first
- Pick a probe diameter just under the opening size
- Plan for articulation only if side walls must be inspected
Borescope or microscope - when to use which?
Use a borescope when the inspection point is hidden, deep or narrow and you cannot open the access. Choose a microscope for freely accessible surfaces that need high magnification and measurement of fine structures.
Frequently asked questions
Which probe diameter is right?
The diameter must be smaller than the tightest opening. Fine bores commonly use 3.9 to 5.5 mm, general service 6 to 8 mm. Smaller probes usually deliver lower resolution.
Do I need an articulating probe?
Only if you must inspect side walls or branches on purpose. A steerable head raises the price but saves repositioning in angled ducts and cavities.
Is an inspection camera waterproof?
The probe is usually rated IP67 and suited to brief immersion. The control unit itself is often less protected - check the rating of both parts separately.
