The IK rating is defined in European Standard EN 62262 and its international counterpart – IEC 62262:2002. It may be used to determine the degree of protection against impact (vandal-proof properties) of the cameras used for monitoring and other devices. IK rating allows to determine the degree of protection provided by enclosures against external mechanical impacts.
IKxy code includes IK letters and a code (‘00’ to ‘10’ scale). The higher the IK code, the higher the mechanical strength. The IK code allows to determine the degree of protection of the camera and to select the device optimal for the application. High IK code cameras can be used to avoid the need to often replace devices as a result of damage due to impact, e.g. by damage by vandalism. To make sure the camera we want to purchase provides a required degree of protection, check its IK code.
Table shows relevant IK codes and corresponding degree of protection against impact energy.
