Conventional concealed weapons detection portals, deployed worlwide at airports, governent buildings, courthouses, and other security critical facilities, are challenged by today's need for stringent and effective entry point screening. Modern threats, like exotic lightweight handguns, are becoming increasingly difficult to detect. Conventional portals do little, if anything, to assist security personnel in resolving the true nature of a potential threat. Systems that rely on blind operator intervention for alarm resolution invite too much human error so security is ultimately compromised. These systems do not instill confidence in the operator or the general public and thus do not present the necessary deterrent to those with sinister intent. Increased detection and improved discrimination do not adequately advance the utility of these security tools. High precision alarm object location information presented to the operator will result in the rapid resolution of the potential threat. Providing this information to the person under scrutiny via a static or streaming video image can enable self-divesting of the offending item without the need for security personnel intervention. Robust detection, effective discrimination, and precise object location information will result in superior entry point screening operations.
