IP AND NEMA RATINGS OF CCTV PRODUCTS
Security equipment is not just for retail showrooms and back offices anymore. It’s all over the place and just as likely to be outdoors as it is indoors. There are two commonly used rating systems to indicate how well an electronic product will withstand environment factors. The “IP” rating system officially stands for “Ingress Protection”. (Don’t confuse this with the acronym for “Internet Protocol” which is something entirely different.) The IP rating is specifically used to rate particle (dust) protection and water protection. The “NEMA” rating system was created by the United States “National Electrical Manufacturers Association”. This rating system is similar to the IP system but also rates the degree of protection against corrosion, gasket aging, and construction practices.
