DTC Offender Alert Passive Scan TM

Offender Alert Brochure
Offender Alert Passive Scan™ is a ‘next generation’ walk-through detector scanning unit. This patented & trademarked product is an advanced passive scanning system for detecting and identifying concealed threats. The versatility of the system allows for covert installation & detection around a doorway, with no visual presence (limitations apply). It can also be deployed as a standalone unit for portable operations that are totally autonomous with a battery pack that provides 180 hours of service. Contrary to the current scanning and detection technology in the market, the Offender Alert Passive Scan™ system emits no energy.
The passive scan consists of sensors that read the constantly changing local magnetic variation. The system creates an “invisible curtain” in the doorway and, when activated, establishes a “normal” or “ambient” baseline reading.  Because the earth’s magnetic field is never static, the system will constantly self adjust. When a subject passes through the system with a metallic object, an invisible wave of variation is detected.
The program provides a visual image of where the items are located on the suspect, as well as an approximation of the size of the item (with optional equipment).  With cameras available at the facility, the system will instantly relay the image of the suspect, position and time of the offending 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 in the market utilize x-rays. They emit a signal from one side, to the other, passing through the subject. They read the variation (loss of transmission) from “sent” to “received” in the same way as an x-ray machine, but weaker by degrees. While these scanning systems are commonly used, there is no evidence to support that they are safe. There are 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 passengers 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.” The 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 Offender Alert stand alone 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. The DTC system allows for logging into the computer memory 24/7 enabling unmanned operation using infrared technology 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 the competitors active scan units, with greater effectiveness and guaranteed long-term safety. Further, The scanner is technically advanced in design and function and is backed by a lifetime warranty on factory defects.
