Product Description

Product Description

 

VT2400F Composite Security Detector
The  VT2400F  composite   security  detector   system  consists  of  a  main  unit, backup battery, charger, carrying case, semiconductor junction tester, metal junction tester,  mechanical  timing  tester,  electronic  timing  tester,  and  headphones.  The integrated  main  unit  combines  nonlinear  junction  detection  with  electronic  audio monitoring.  The  nonlinear  junction   detector  identifies  various  targets   containing semiconductor junctions  and  metal  corrosion  junctions,  while  the  audio  receiver captures mechanical timing device signals including pointer movements, mechanical oscillations, current noise, electronic pointer signals, and switch operations through both air and material transmission. To address the widespread use of timing crystals in  electronic  timing  devices  for  improvised  explosive  devices  (IEDs), the  system incorporates advanced signal processing technology to detect timing crystal oscillat- ions. This innovation enhances detection accuracy for such devices while reducing false alarm rates in complex indoor electronic environments.
The   VT2400F   composite   security   detector   is   specifically



  engineered   for explosive detection and security screening operations. Leveraging our organization's three-decade  R&D  expertise  in  nonlinear  junction  detectors,  we  have  conducted comprehensive  analysis  of  user  requirements  and  global  technical   standards.  To address the operational demands of diverse scenarios and security deployment across China's vast regions, the device has been optimized for user-friendliness, endurance in various environments, nonlinear detection range and penetration capability, as well as electronic  listening  applications  in  explosive  detection.  Key  technical  features  and advancements include:
    It has good detection and listening performance,  strong penetration  ability and high target listening and positioning accuracy.
    The system adopts low delay design, with fast response speed and good real- time performance, and the startup time is less than 3 seconds.

    The  receiver  uses  high-fidelity  signal  processing  technology  and  anti- electromagnetic  interference  monitoring  earphones,  and  has   good  target discrimination.
    The special design of electronic timing crystal oscillator is made, which can detect all kinds of timing crystal oscillators.
    The battery has a wide temperature range from-40ºC to +55ºC and a high energy density.

1  basic function
The  VT2400F  composite  security  detector  is  mainly  used  for  searching  and  eliminating  the explosive devices, preventing the eavesdropping and the peeping, and realizing the detection of the explosive devices, the eavesdropping and the peeping devices. ( 1)The  semiconductor  junction  and  the   metal  corrosion  junction  can  be   detected   and identified. (2)Mechanical and electronic timing devices under detectable working conditions; (3)Electronic device with semiconductor components in both detectable and non-detectable states; (4)When the electronic device containing  semiconductor components and metal corrosion junctions are detected, the system will issue an audio-visual alarm; (5)When   mechanical   timing   device   and   electronic   timing   device   are   detected,   the characteristic sound of them can be heard through the earphone. (6)The electronic listening device can hear the characteristic sound of the tested object in real time, and can distinguish the mechanical, electronic pointer, electronic digital display, quartz timing device.
