Embodiments of methods, devices and systems are presented for communicating information in an explosive environment. An explosion proof video and data communication module includes features that prevent the generation of a spark or other ignition sources that could ignite explosive dust, gas or vapors in the air. The explosion proof video and communications relay modules may operate independently or as a group to provide real-time information, situation awareness, functionally and responsiveness for personnel that are in explosive environments.
