?Passive Security Scan™ is a ‘next generation’ walk-through personnel scanning system. This patented product (US Patent: 7408461?) is an advanced passive scanning technology for detecting and identifying concealed threats. The versatility of the system allows for covert installation and detection around a doorway frame, with no visual presence (some limitations apply). It can also be deployed as a standalone unit, for portable battery powered operations that are totally autonomous, with the battery pack providing well over 180 hours of service, depending on the option purchased. Contrary to the current scanning and detection technology in the market, the Passive Security Scan system emits no electromagnetic energy or other harmful radiation.
Passive Security Scan utilizes the newest sensing technology available today. Its sensors read the constantly changing local magnetic variations due to the Earth’s magnetic properties. The system creates a virtual “invisible curtain” in secure zone entrances. Due to the dynamic nature of Earth, the system self calibrates to establish ambient baseline readings, which are then distorted when weaponry or other contraband is present during scanning.
The Passive Security Scan is a very portable security device which can be operated in Stand Alone, connected, or wireless modes, using AC or DC power, including solar.

Traditional detectors use emissive imaging, or active scanning -the same type of technology that can have harmful effects after prolonged exposure; the Passive Security Scan eliminates any exposure to students through passive sensing detection. When students step through the Passive Security Scan, sensors embedded within the aluminum frame provide a reading and alert security personnel to the level of threat with color-coded LED lights and an audible buzz.
Passive Security Scan also can be operated with a desktop or laptop computer, or tablet using the Passive Security Scan application for Windows or Android, connected via USB or Bluetooth, to give an instant view of the scanned patron. This data can then be transmitted to other handheld devices throughout the facility for threat tracking and neutralization.

The Passive Security Scan can be set to specific levels of detection, giving the facility the ability to “ignore” cell phones and Mp3 players, but still detect more serious threats. The unit can scan one person in 1.2 seconds or 300 in 10 minutes.
The available software applications can provide a visual image of where the items are detected and located on the suspect, as well as an approximation of the size of the item. With cameras available at the facility, the system can instantly relay the image of the suspect, along with position of the item detected and time of the alert. The picture can be transmitted to security, management or any designated recipient and can be retained in the memory log of the computer. The unit can have the threshold level set to memory and operate without the computer link, provided that it is manned for an immediate response when breached.
The existing systems currently on the market utilize active scanning, meaning that they emit radiation using various wavelengths, such as X-rays and millimeter microwaves. In these systems, a signal is emitted from one side of the scanner to the other side of the scanner, passing directly through the patron being scanning. They then read the variation, or loss of transmission, from the “sent” to “received” sides, much in the same way as an X-ray machine emits X-rays though an object, like a broken arm, to expose the film on the other side of the arm. While these scanning technologies are commonly used, there is no evidence to support that they are safe. There are many studies that identify the long-term effects of this technology, which has been shown to have caused cancer in other applications.
It has been widely speculated that a subject who repeatedly passes through such a system can be seriously affected, as cited in the New York Times on January 2010, “The plan for broad use of X-ray body scanners to detect bombs or weapons under airline passenger’s clothes has rekindled a debate about the safety of delivering small doses of radiation to millions of people” — a process some experts say is certain to result in a few additional cancer deaths.”
These scanners are called “backscatter scanners” and some radiation experts believe the amount of radiation is minimal and creates negligible risk, other experts agree that collective exposure could incrementally increase the risk of fatal cancers in those who are frequently exposed to even small amounts of radiation. In a 2002 report on the safety of backscatter scanners, the National Council on Radiation Protection and Measurements, which is influential in setting regulatory standards, said it “cannot exclude the possibility of cancer, attributable to radiation of this type, in people, repeatedly exposed to very low doses of radiation.”
The Passive Security Scan stand-alone system is priced at less than half the relative cost of similar units now in use in the marketplace, all of which are “active” rather than “passive” units, and none of which provide a memory log of scans. Our system allows for logging into the solid-state memory 24/7, enabling unmanned operation to record night intruders. (with optional equipment). The unit allows for installation at multiple locations at a cost that is less than just one of our competitor’s active scan units, with greater effectiveness and guaranteed long-term safety. Further, Passive Security Scan is technically advanced in design and function and is backed by a lifetime warranty on factory defects.
