What type of camera should be used in Zone 1?

For use in Zone 1 hazardous areas, where there is a continuous, high risk of explosion, the following types of cameras can be suitable:

• Explosion-proof (Ex d) Cameras
  • These cameras have an enclosure that can withstand the pressure of an internal explosion and prevent the ignition of the surrounding explosive atmosphere.
  • The enclosure is designed to contain any explosion within the camera and prevent it from spreading to the surrounding environment.
  • Examples include cameras certified for use in compliance with IEC/EN 60079-1 standard.
• Increased Safety (Ex e) Cameras
  • These cameras have additional safeguards to prevent the occurrence of arcs, sparks, and excessive temperatures that could ignite the surrounding explosive atmosphere.
  • The electrical components are designed and constructed to ensure a higher degree of protection against the risk of explosion.
  • Examples include cameras certified for use in compliance with IEC/EN 60079-1 standard.
• Intrinsically Safe (Ex i) Cameras
  • These cameras have electrical circuits designed to limit the energy and temperature of the components, ensuring they cannot ignite the surrounding explosive atmosphere.
  • The power supply and other electrical components are designed to be intrinsically safe.
  • Examples include cameras certified for use in compliance with IEC/EN 60079-1 standard.
