Hazardous & Explosion Proof Video Surveillance

Author: Brian Rhodes, Published on Mar 24, 2016

Placing surveillance cameras in hazardous, highly flammable environments call for equipment certified not to spark or ignite. These requirements are far more stringent than typical surveillance gear.  Because of these elevated requirements, cost is much more expensive. Inside, we discuss:

  • Where is Explosion Proof Equipment used?
  • What are the ratings? Including NFPA 70, EX, Division 1, Division 2, and ATEX directives 95/137
  • What do the ratings mean?
  • Hazardous Rated Camera Options including Axis, Bosch, Moog, Pelco, and IVCCO.
  • Typical Product Cost
  • Alternatives to using rated equipment?
