Surveillance cameras have become an absolute necessity in various industrial and non-industrial settings. From our households to offices to manufacturing and construction facilities, CCTV cameras have now evolved into a more urbane, strong and smart device. In mundane day-to-day working, the cameras are not much vulnerable, when it comes to triggering fire or explosion. But in high-risk combustible working atmospheres such as petrochemicals, oil and gas processing plants, any standard surveillance camera can create trouble and end up costing lives and properties.
