Look for cameras with stamped certificates showing compliance for your specific zone and temperature class. For example, markings like “II 2G Ex db IIC T6 Gb” indicate suitability for Zone 1 gas environments with a temperature rating of T6 (≤ 85°C).
Key Safety Certifications for Cameras
Overview of ATEX Certification
ATEX, short for "ATmosphères EXplosibles," is a European safety standard. It certifies equipment suitable for use in explosive atmospheres. When selecting an explosion-proof camera, ATEX certification indicates that the device has undergone rigorous testing. It ensures the camera won't generate sparks, heat, or electrical energy capable of igniting gases or dust in hazardous zones. ATEX-certified cameras are marked with specific codes, such as "II 2G Ex db IIC T6 Gb," which specify their suitability for certain zones and temperature classes. Ensuring your camera bears the correct ATEX mark is crucial for compliance and safety in European hazardous environments.
Understanding IECEx Standards
IECEx is an international safety certification system. It harmonizes standards across countries, making it easier for companies to operate globally. IECEx-certified cameras have passed standardized testing for safety, reliability, and performance in explosive atmospheres. This certification covers a broad range of hazardous zones, including gas and dust environments. Using IECEx-certified equipment simplifies international procurement and ensures consistent safety standards. When selecting a camera, check for the IECEx mark and corresponding certificate number to confirm compliance.
UL Certification for U.S. Compliance
UL, or Underwriters Laboratories, is a U.S.-based safety organization. UL certification indicates that the camera meets strict safety standards for electrical devices used in hazardous locations within the United States. UL-certified explosion-proof cameras are tested to prevent sparks or heat emissions that could cause explosions. They often feature markings like "Class I, Division 1," which specify their suitability for specific hazardous zones. For companies operating in the U.S., choosing UL-certified cameras guarantees adherence to local safety regulations and reduces legal risks.
Note: Always verify the certification documents and ensure they match your specific hazardous zone classification. Proper certification confirms the camera’s safety and compliance, protecting personnel and assets.
IP Ratings and Their Importance (IP68, IP67)
IP ratings define how well a camera enclosure protects against dust and water ingress. For explosion-proof cameras, high IP ratings are essential to maintain safety and functionality in tough environments.
IP67 means the camera is dust-tight and can withstand immersion in water up to 1 meter for 30 minutes. This rating suits many industrial settings where occasional water exposure or dust is present but not constant submersion.
IP68 offers even greater protection, allowing continuous immersion in water beyond 1 meter depth. Cameras with this rating are perfect for environments with heavy rainfall, flooding risks, or cleaning processes involving water jets.
Selecting a camera with IP67 or IP68 ensures reliable operation despite dust, moisture, or water exposure. It also helps maintain the explosion-proof integrity by preventing hazardous materials from entering the housing and causing internal sparks or corrosion.
Summary Table: IP Ratings
| Feature | Benefit | Application Example |
| IP67 | Dust-tight, short-term water immersion | Dusty factories, occasional water exposure |
| IP68 | Dust-tight, long-term water immersion | Flood-prone areas, heavy washdowns |
Camera Quality and Performance
Resolution and Image Clarity
Choosing an intrinsically safe industrial explosion-proof camera means prioritizing image quality. High resolution is essential for capturing detailed visuals that help identify equipment issues, leaks, or corrosion early. Cameras offering at least 2 megapixels (MP) deliver clear images suitable for inspections and documentation. For example, a 1920×1080 pixel resolution ensures sharpness and detail, allowing safety personnel to detect small defects or hazards that might otherwise go unnoticed.
Image clarity also depends on sensor quality and lens optics. Wide Dynamic Range (WDR) technology helps the camera handle scenes with both bright and dark areas, preventing loss of detail in shadows or highlights. This is especially important in industrial settings where lighting can vary significantly.
Low-Light Performance and Night Vision
Many hazardous industrial environments have poor lighting—think underground tunnels, offshore rigs, or dimly lit chemical plants. Cameras must perform well under these conditions to maintain safety and operational oversight.
Look for cameras with excellent low-light sensitivity, often measured in lux. A camera capable of capturing images at 0.001 lux (color) or even 0.0001 lux (black and white) can produce usable images in near darkness. Infrared (IR) illumination extends visibility in total darkness without adding visible light that might interfere with operations.
Night vision capabilities combined with low-light performance ensure round-the-clock monitoring, reducing blind spots and enhancing security.
Optical Zoom Capabilities
Optical zoom allows users to magnify distant objects without losing image quality, unlike digital zoom, which degrades clarity. This feature is vital for inspecting hard-to-reach areas or equipment from a safe distance in hazardous zones.
A camera with at least 10x optical zoom enables detailed examination of pipes, valves, or electrical panels without exposing personnel to danger. This zoom capability supports preventive maintenance by identifying early signs of wear or failure remotely.
Durability and Ruggedness
Waterproofing and Dust Resistance
In hazardous industrial settings, explosion-proof cameras face harsh conditions daily. Dust, water, and moisture can easily damage equipment not designed to resist them. That’s why waterproofing and dust resistance are essential features for these cameras.
Look for cameras with high IP ratings, such as IP67 or IP68. IP67 means the camera is completely dust-tight and can handle immersion in water up to 1 meter for 30 minutes. IP68 offers even stronger protection, allowing continuous immersion beyond 1 meter. This is crucial in environments exposed to heavy rain, flooding, or regular washdowns.
Dust resistance prevents fine particles from entering the camera housing. Dust can cause internal damage, short circuits, or degrade image quality. A well-sealed camera housing protects delicate electronics and maintains safety by preventing sparks or heat from igniting flammable dust.
Waterproof and dustproof cameras help maintain reliable operation and reduce maintenance costs. They also ensure the explosion-proof integrity remains intact, avoiding dangerous breaches that could lead to accidents.
Shockproof and Temperature Tolerance
Industrial explosion-proof cameras must endure physical shocks and extreme temperatures. They often get bumped, dropped, or exposed to vibrations from heavy machinery. Cameras designed to be shockproof protect internal components from damage caused by impacts or drops.
Shock resistance extends the camera's lifespan and reduces downtime caused by repairs or replacements. Look for models tested to survive multiple drops or impacts without losing functionality.
Temperature tolerance is equally important. Hazardous areas can experience extreme heat or cold, depending on the industry and location. Cameras that operate reliably across a wide temperature range ensure continuous monitoring, regardless of ambient conditions.
For example, a camera rated for -40°C to +60°C can be used in cold storage facilities or desert oil fields without risk of failure. Maintaining stable performance in temperature extremes prevents safety blind spots and costly equipment downtime.
