Zistos Corporation of Holbrook, New York, has introduced an advanced tool for cargo security and counterterrorism operations. The Explorer-SCOPE is a videoscope that allows an inspector to make a complete visual assessment of shipping containers and other cargo vessels through a 10-millimeter hole. There is no need to open doors or hatches. Designed for portability, the device is battery powered and combines a powerful laser light source with electronically enhanced low-light video and a built-in high-resolution monocular. It can generate images as far as 40 feet away in complete darkness.
