If you are working in harsh environments, then you may need an explosion resistant IP-camera such as the Dexcam 20 from Dexter Systems. This IP66 rated IP camera is also rated as “a compact and lightweight network day/night IR 20X HD 1080p 16:9 format zoom dome camera that has been designed for use in potentially explosive atmospheres and harsh environmental conditions.” We’ve heard of water resistant and heat resistant but this goes to a whole new level.
