A few years ago at physical security industry conferences the word I heard the most was “convergence”. At that time the meaning of it was how Physical Security and IT were coming closer together, and it was a hot topic because analog technology was quickly giving way to IP-based approaches. With access control becoming tied to identity management, and surveillance being managed, stored, and analyzed on computer networks, it’s easy to see now why that convergence was critical for the industry and one that required rethinking old approaches.
