Explosion proof camera housings are made from stainless steel. Stainless steel consists of chromium, nickel, carbon and manganese. Stainless steel 304 is a popular alloy for its durability, appearance and resistance to corrosion.
However, in situations where there might be acidic material, industrial solvents or highly concentrated saline environments present, 316 stainless steel would be required. 316 stainless steel has the same metal alloys as 304 along with an alloy called molybdenum that would make the stainless steel more durable with the ability to withstand very harsh environments. 316 explosion proof security cameras are 20 to 50% more expensive, but in some conditions there is no better option than using 316 explosion proof stainless steel.
There are two main specs to consider when purchasing an explosion proof housing. One is the explosion proof classifications required; the other is the internal dimensions of the housing to fit the security camera that would go inside the housing.
When estimating the internal dimensions of the explosion proof housing, you must carefully make sure there is extra space for the connectors to connect on the back of the camera and enough space for the cable.
There are many occasions where a customized explosion proof housing for an existing camera is required. Sometimes the cameras required might not just be for security, such as using a Sony or Canon high resolution, high frame SLR camera to take photos close to rocket launch pad. Those cameras with large lenses tend to be bigger than any existing explosion proof housing. The explosion proof housing helps protect the camera from damage and can be reusable. Explosion proof housings have been proven to be an effective option for harsh environments.
