Vandal Resistance/IK Rating Guide
"Vandal-proof" is a term often used by manufacturers to market their products, but the reality is that these specifications are mostly self-determined and cannot be trusted.
In this 16-page guide, we explain how vandal resistance (IK ratings) of cameras are determined and how realistic they are, examining:
- What are IK ratings and how are they determined?
- What standards are used?
- How manufacturers may game the standards
- How manufacturers use/abuse generic "vandal" terms
- How IK ratings are tested
- What testing is defined in the standards and what is left up to manufacturers?
- Most common points of failure in IPVM IK testing
- Are some materials better than others?
Plus, upcoming, based on IPVM's new internal vandal-resistant test rig, IPVM will release individual reports on which manufacturers and models passed or failed.
