What is the Right Endoscope or Borescope for Industrial Use

Introduction

inspection technology has become a cornerstone of preventive maintenance, diagnostics, and operational safety. Two of the most critical tools for internal visual inspection are the borescope and endoscope. Though originally from different fields, they’re now widely used across automotive, plumbing, HVAC, and manufacturing industries. This article complements our earlier article "Choosing the Right Borescope Camera: A Buyer’s Guide" but in this guide we are given more reasons to make an informed decision and the major difference between an industrial endscope and borescop

Choosing the right tool for your application isn’t just about specs—it’s about selecting the correct diameter, flexibility, resolution, and lighting to match your inspection task.
Get this wrong, and you risk poor diagnostics, equipment damage, or wasted costs.

Key takeaway: Whether you’re peering into a car engine, a pipeline, or a complex piece of machinery, using the right inspection camera helps you work faster, safer, and more efficiently.

What’s the Difference Between a Borescope and an Endoscope?

While the terms are often used interchangeably in online marketplaces, they originally served different purposes:

• Borescopes are designed for industrial applications and are often rigid or semi-rigid, making them ideal for inspecting machinery, engines, and static structures.

• Endoscopes, in contrast, are typically more flexible, and while originally used in medical contexts, they’ve become common in inspecting softer pathways like plumbing and HVAC ducts.

Key Industrial Use Cases

Let’s break down the practical, real-world uses where a borescope or endoscope becomes essential:

Automotive Inspections

• Cylinder and piston checks

• Combustion chamber inspections

• Timing belt and valve assessments

• Turbocharger diagnostics

Relevant Tool: Shinano SI-1490B Air Impact Wrench – Often used alongside borescopes in engine work.

Plumbing and Pipework

• Clogged drains and pipe blockages

• Leak detection inside walls or underground systems

• Corrosion checks in metallic pipelines

HVAC Systems

• Ductwork inspections for mold or blockage

• Coil corrosion and airflow restriction checks

Aircraft and Aviation Maintenance

• Jet turbine checks

• Structural inspection of tight compartments

• Scheduled airframe diagnostics

Inspection Accessory: Maxxeon WorkStar 5000 – Area Light – Ideal for illuminating inspection environments.

Heavy Machinery & Manufacturing

1. Visual diagnostics for gearboxes, bearings, and mechanical systems

2. Routine preventive maintenance

Matching Accessory: Shinano SI-2210 Belt Sander – Surface prep after internal inspection

Important Features to Consider

To choose the right inspection camera, you must understand the technical specs that impact functionality:

Camera Resolution

The higher the resolution, the more detail you'll capture:

• 720p: Basic level for simple diagnostics

• 1080p or 2MP+: Ideal for clear imaging in automotive and manufacturing

• 4MP+ or dual lenses: Professional-grade inspections

If you’re inspecting critical moving parts or corrosion, always opt for HD or above.

Product mention

For clear 1080p resolution on a budget, try the

INSKAM 4.3” IPS Screen Dual Lens Borescope – $29.90

Why it works: Cheap, IP67 waterproof, perfect for engine inspections.

Advanced Tool: INSKAM 4.3” IPS Screen Dual Lens Borescope – $29.90

Cable Type & Length

• Rigid borescopes are great for straight-line access like engine blocks.

• Semi-rigid cables offer slight flexibility, suitable for most HVAC or pipe jobs.

• Flexible endoscopes work well for winding plumbing systems or irregular ductwork.

Lengths range from 1 meter (for desktop work) to 15+ meters (for underground pipelines).

Product Mention

For long-range plumbing inspection,

VEVOR Sewer Camera – 150FT Cable, IP68 Waterproof – $454.99

Why it works: This serves those looking for high-ticket, ultra-long probes like those often listed in Amazon/Reddit forums.

Probe Diameter

Critical for access in tight areas:

• 3.9mm – 5.5mm: Needed for spark plug holes, injectors, or tight cavities

• 6mm – 10mm: Best for general pipe inspections, HVAC ducts, and engine chambers

Lighting & Waterproof Ratings: Why They Matter

LED Lighting

Lighting is non-negotiable since inspections often occur in dark, narrow, or enclosed spaces.

Most modern borescopes and endoscopes come with built-in adjustable LEDs—typically 6 to 12 diodes near the camera tip. Features to consider:

• Adjustable brightness: Prevents glare in reflective surfaces like pipes or engine walls
• Shadow reduction: Ensures even lighting in cylindrical or deep compartments
• Color temperature: White or daylight LEDs yield better detail in video capture

Pair with: Maxxeon WorkStar 620 Technician’s Light – For external task area illumination before or after camera inspection.

Waterproof Rating (IP67, IP68)

Make sure your device has a strong IP (Ingress Protection) rating for plumbing, outdoor construction, and marine inspections.

• IP67: Can be submerged in up to 1m of water for 30 minutes – suitable for most indoor pipe checks
• IP68: Deeper submersion, great for wastewater, underground, or rainy environments

4.3” Industrial Endoscope with 10M Cable – $30.98

Display Types: Built-In vs. Wireless

When it comes to monitoring your inspection in real-time, you have two major options:

Built-In Screen

• No need for external devices
• Faster setup and deployment
• Ideal for workshops or field techs who don’t want to depend on smartphones
  

 Wireless (Wi-Fi or USB)

• Camera connects to your smartphone, tablet, or PC
• Offers app-based features like video recording, zoom, and screenshot
• Perfect for mobile inspections or digital documentation

Some high-end models even offer dual modes: screen + wireless streaming.
