Industries such as oil and gas, chemical processing, and aerospace often require detailed inspections of confined and hazardous areas. However, traditional inspection methods can expose workers to safety risks, leading to costly operational shutdowns.
Intrinsically safe borescope cameras provide a solution by allowing professionals to conduct non-destructive testing (NDT) without endangering personnel or equipment. These devices comply with international safety certifications, ensuring they can be used in hazardous locations without the risk of sparks or excessive heat.
This guide explores how intrinsically safe borescope cameras improve industrial inspections, key features to consider, and why they are a necessity in high-risk environments.
Why Choose an Intrinsically Safe Borescope Camera?
Intrinsically safe borescope cameras are designed to operate in hazardous environments where traditional devices could pose ignition risks. Unlike standard borescopes, these specialized cameras meet stringent safety certifications, making them suitable for ATEX, IECEx, and NEC Class I, II, and III hazardous locations.
Key Benefits
- Enables non-destructive testing in confined or high-risk areas
- Reduces downtime by allowing inspections without equipment disassembly
- Prevents sparks and excessive heat buildup, minimizing explosion risks
- Captures high-resolution images and videos for compliance and documentation
- Improves worker safety by limiting direct exposure to hazardous zones
Factors to Consider When Choosing a Borescope Camera
1. Safety Certifications
For operations in hazardous environments, compliance with safety standards is essential. The most recognized certifications include:
- ATEX (Atmosphères Explosibles): Required for use in explosive atmospheres within the European Union
- IECEx (International Electrotechnical Commission Explosive Atmospheres): Ensures global compliance for electrical equipment in hazardous areas
- NEC 500 / Class I, II, III Divisions: Defines U.S. safety classifications for different hazardous locations
Before purchasing a borescope camera, confirm that it meets the necessary safety regulations for your specific industry.

2. Image and Video Resolution
A high-resolution camera ensures that small defects, cracks, or corrosion are visible during inspections. Look for:
- 1080p Full HD or 4K resolution for clear imaging
- Optical and digital zoom functions for detailed inspections
- Adjustable focus and exposure settings for various lighting conditions
3. Lighting and Illumination
Many confined spaces lack sufficient lighting, making onboard illumination a crucial feature. Consider:
- LED lighting with adjustable brightness levels
- Infrared (IR) or ultraviolet (UV) options for enhanced visibility
- Fiber optic lighting for uniform illumination in deep or curved spaces
4. Probe Length and Flexibility
The probe must be long enough to reach inspection areas while maintaining maneuverability. Options include:
- Rigid borescopes: Best for straight-line inspections with minimal bends
- Flexible borescopes: Ideal for navigating complex pipe systems and machinery
- Articulating probes: Provide enhanced control over probe movement
5. Durability and Environmental Resistance
Industrial settings demand robust equipment that can withstand harsh conditions. Look for:
- IP67 or higher waterproof rating for wet environments
- Shock-resistant housing to prevent damage from drops or impacts
- Chemical-resistant materials to withstand exposure to oils, solvents, and hazardous substances
