Data Connect

摘要

There's a contradiction built into the idea of an integrated security system. The perfect security system would monitor every square inch of a protected area, send an instant alarm, swing surveillance cameras into place, deny access to intruders and allow access to authorized personnel the instant an event occurs. Although everything would be viewed, the system should only respond to events that concern security. How, from a mass of data, does one distill usable information? With more data, it is harder to know what's significant, but if there's not enough data, something important might get missed.
