Explosion proof camera selection guide systems from Veilux are engineered for the most demanding hazardous environments, certified for Class I Division 1 and Zone 1 areas. Our explosion proof camera selection guide lineup meets ATEX, IECEx, and UL standards.
Explosion-proof cameras for hazardous areas must match three criteria: the area classification (Class/Division or Zone), the gas or dust group (determined by the flammable substance present), and the physical environment (IP rating, material, temperature range). This hub brings together every guide you need to specify, design, install, and maintain compliant hazardous area camera systems.

Every camera selection decision starts with the area classification drawing. These guides explain what each classification means and what equipment it requires:

Quick Reference: NEC vs IEC Gas Groups
| NEC Group | IEC Group | Representative Gases | Industries |
|---|---|---|---|
| Group A | IIC | Acetylene | Chemical, specialty gas |
| Group B | IIC | Hydrogen | Chemical (hydrogenation), chlor-alkali |
| Group C | IIB | Ethylene, ethyl ether | Chemical, petrochemical |
| Group D | IIA | Propane, methane, gasoline | Oil and gas, LNG, refinery |
| Group E | IIIC | Metal dusts (aluminum, magnesium) | Metal processing |
| Group F | IIIB | Carbon black, coal dust | Mining, carbon black |
| Group G | IIIA | Grain, flour, wood dust | Agriculture, food processing |
Group C cameras cover both Group C and Group D areas. Group B cameras cover Groups B, C, and D. Always specify for the most demanding group present.

Frequently Asked Questions
What certifications do explosion-proof cameras need?
Cameras must carry the certification required for the installation jurisdiction: ATEX/IECEx Class I Division 1 (USA), ATEX Zone 1 (EU), or IECEx Zone 1 (international). The gas Group (A/B/C/D or IIC/IIB/IIA) must also match the substance present in each area.
For definitions of key hazardous area terms used in this guide, see the Hazardous Area Classification Glossary.
What is the difference between Class 1 Division 1 and ATEX Zone 1?
Both classify areas with frequently present flammable gas hazards, but they are separate certification systems. Class I Division 1 is the NEC (US) standard; ATEX Zone 1 is the EU/international standard. Equipment must carry the specific certification required for its jurisdiction — a ATEX/IECEx certified camera is not automatically ATEX approved.
For definitions of key hazardous area terms used in this guide, see the Hazardous Area Classification Glossary.
Are explosion-proof cameras the same as intrinsically safe cameras?
No. Explosion-proof cameras contain any internal ignition within the housing. Intrinsically safe cameras limit electrical energy so no ignition can occur. Most surveillance cameras are too power-hungry to be intrinsically safe, making explosion-proof the dominant protection method for camera applications.
