IP Enclosure Ratings & Standards

When it comes to weatherproof or waterproof enclosures, security camera installers need to have a clear knowledge what IP65, IP66 or IP67 mean. In general IP stands for Ingress Protection. IP ratings are given in form of two-digit code, such as IP68 or IP67. The first numerical digit describes the rating that is given for solid objects. The second digit represents the level of protection against fluids. The higher the number, the stronger the level of protection. For detailed information see the chart below.

 1 Protected against dripping water Vertically falling drops
 2 Protected against dripping water when tilted up to 15º Vertically dripping water shall have no harmful effect when the enclosure is tilted at any angle up to 15º from its normal position
 3 Protected against spraying water Water falling as spray at an angle up to 60º  from the vertical hasn’t any harmful effect
 4 Protected against splashing water Water splashed against the enclosure from any direction  hasn’t any harmful effect
