PALMDALE, CALIF. – Delta Scientific, the leading manufacturer of counter-terrorist vehicle control systems used in the United States and internationally, today announced that its new DSC 400 Early Warning System uses Doppler Radar and Digital Loop Detector technology to alert guards to activate security measures, including raising their Delta vehicle barricades.  Continuous Doppler Radar picks up instantaneous changes in velocity and addresses the potential threat of an inbound vehicle approaching at normal speeds and then accelerating to attack.  It also warns if a hidden vehicle suddenly passes a larger vehicle and attempts an attack. “The DSC 400 Early Warning System is best applied at locations where there is a long and relatively straight run into the facility that would allow a large vehicle to build up its speed,” explains David Dickinson, Delta Scientific senior vice president.  “A vehicle traveling at 60 mph (96 kph) can cover 88 feet per second (2.68 m/sec) so it is imperative that the guards be alerted immediately.  Every second counts.” The Delta DSC 400 Early Warning System consists of radar antennas that look like and install similar to video surveillance cameras.  They can be positioned on top of guard booths or on poles looking into the facility or out.  The system includes the circuitry and logic to trigger an alarm panel when a preset speed is exceeded or when a vehicle drives in an exit lane while attempting to go around a guard booth. The new DSC 400 Early Warning System is now available.  More information is available at www.deltascientific.com or info@deltascientific.com.
