Over the past few years, Japan has once again been reminded of nature's devastating power to inflict damage and destruction on people and property. In order to respond effectively to such disasters, accurate evaluation of the nature of the emergency, together with immediate implementation of targeted search and rescue operations, is critical. Statistically, the survival rate of victims trapped in collapsed buildings and other structures drops rapidly once 72 hours have elapsed from the time the disaster struck, literally making it a race against time. This paper discusses various imaging solutions offered by NEC that have been specifically designed to facilitate faster and more effective emergency response - from determining the scale and nature of the disaster to implementing search and rescue operations.

The proliferation of weapons and the rise of terrorism have caused us to face various threats that were hitherto inconceivable. By focusing on sensor technologies, NEC's Radio Application, Guidance and Electro-Optics Division is developing and proposing surveillance systems in the public safety domain to support the implementation of the "safe and secure society." This paper introduces some of the imaging technologies, including the downsizable uncooled infrared (IR) sensor technology and one for an underwater surveillance system for monitoring suspicious underwater incursions that are hard to detect. We also discuss aspects of the integrated collaboration needed in applying these technologies as well as the types of major conceivable threats and the sensors that will deal with them.
