Choosing the Right Borescope

Can it go into drains and pipes? What pipe diameter is workable?

Yes. A 6.2mm or 8.5mm probe on a flexible cable feeds into sink drains, traps and pipes roughly 1 inch and larger. For tight P-traps choose a smaller, more flexible probe; for longer runs choose a 2–3m cable.

Is it waterproof enough to submerge in a drain?

The probe and cable are IP67-rated, so they can be submerged briefly (up to 1m) in a wet or flooded drain. Keep the display unit or your phone dry — only the insertion tube and camera head carry the waterproof rating. After use, clean the probe and dry it thoroughly to prevent corrosion.

What cable length and type should I use for pipe inspection?

Use a flexible cable so it follows the bends in the plumbing, and pick a length that reaches the blockage — 1m for under-sink work, 2–3m for longer branch lines. A semi-rigid cable helps push through longer horizontal runs.

FAQ

What is a borescope and what is it used for?

A borescope is an inspection camera designed to access hard-to-reach areas. It is widely used for automotive diagnostics, pipe inspection, HVAC maintenance, and industrial applications.

How do I choose the right borescope?

Choosing the right borescope depends on your needs. Key factors include probe diameter, cable length, articulation (2-way or 4-way), and whether you need a standalone screen or smartphone connection.

What industries are your inspection cameras suitable for?

Our borescopes are used across multiple industries, including:

  • Automotive repair
  • Plumbing and drainage
  • HVAC inspection
  • Construction and maintenance
  • Industrial equipment inspection
How long does the battery last?

Battery life depends on the model, but most standalone borescopes provide 3–5 hours of continuous use on a full charge.

Which borescope is best for beginners?

For beginners, we recommend starting with a model that has a built-in screen and simple controls. These models do not require additional setup and are easier to operate.
