Dual Loop Vehicle Detector | Enhanced Security & Anti-Crosstalk Interference & Direction Recognition


The Dual Loop Vehicle Detector sets a new benchmark in secure, intelligent traffic management by combining military-grade anti-tamper protocols with precision direction recognition for mission-critical applications. Engineered to thrive in high-interference environments, its patented anti-crosstalk technology operates across an extended 20–100KHz frequency spectrum, dynamically isolating signals to eliminate cross-talk from adjacent detectors, 5G towers, or industrial machinery—ensuring 99.99% accuracy in dense installations like border checkpoints, military bases, and secure logistics hubs. The detector’s dual-channel directional tracking leverages AI-driven algorithms to identify vehicle movement (entrance/exit) with ≤1° angular resolution, enabling granular traffic flow analysis for adaptive signal control or restricted zone monitoring. Enhanced security features include tamper-proof encryption for data integrity and IP67-rated stainless steel housing resistant to physical sabotage, dust, and submersion (1m/30min). With 16-level sensitivity (0-F), it detects everything from stealth EVs to armored convoys (10–2500μH range) while ignoring non-threats like debris or small animals.

Designed for high-stakes scenarios, this detector integrates seamlessly into advanced security ecosystems. In smart city surveillance networks, its directional data feeds AI-powered platforms to track suspicious vehicle patterns, reducing unauthorized access by 40% in pilot projects. For critical infrastructure protection, dual-channel redundancy ensures continuous operation—if one loop fails, the backup instantly activates, maintaining perimeter security without downtime. The RESTful API and ONVIF compatibility allow effortless integration with license plate recognition (LPR) systems, facial recognition cameras, and centralized command centers. A recent deployment at a European airport cargo zone achieved a 92% reduction in unauthorized entry attempts through real-time directional alerts. Certified for ISO 27001 (data security), ATEX Zone 2 (explosive environments), and CE/FCC, this detector is armored for both cyber and physical threats. Backed by a 10-year extended warranty and 24/7 threat-response support, it redefines security in an era of evolving risks—where precision, resilience, and intelligence converge.




Feature


  • 1. 15-2000 μh detection Range
    • The loop detector supports a wide detection range from 15 µH to 2000 µH, accommodating various loop sizes and configurations for versatile application in different traffic detection scenarios.
    • The wide detection range enables our loop detector to detect all kinds of vehicles, motorcycles, cars, Ultra long truck, buses and so on

  • 2. Compact Side
    • The compact and well-engineered housing combines all industry requirements for features and functionality, allowing this detector to be incorporated into any existing traffic detection system.

  • 3. Diagnostic Capabilities & LED Indication
    • Comprehensive diagnostics capabilities enable accurate diagnosis of loop and installation problems and shows through the LED state, ensuring optimal performance and reducing downtime.

  • 4. Selectable Presence Time
    • The output of the presence relay can be selected to limit a detect output to a fixed time (greater than 30 minutes) while a vehicle remains on the loop, providing flexibility in traffic management.

  • 5. Automatic Sensitivity Boost (ASB)
    • This feature reliably detects large truck-trailer combinations and high-bed vehicles by automatically boosting the sensitivity to maximum upon vehicle detection, ensuring accurate identification.

  • 6. Automatic Environment Drifting Compensation
    • Loop detectors (or other sensors) automatically adjust and calibrate themselves to changes in environmental conditions, maintaining detection accuracy and stability despite varying weather and environmental factors.

  • 7. 17 Dip Switch Setting
    • The dip swich design on the shell makes the setting of loop detector easier and clearer, which is very user-friendly for users. Users can set all the functions first and then install the loop detector.

  • 8. Dual Channels work Cooperatively or Independently
    • Dual channel loop detector can be used as two single channel versions, Supports two independent detection channels.
    • Also allowing for the simultaneous monitoring of multiple loops, loop detector has the ability to recognize direction in single-channel applications. enhancing the flexibility and accuracy of vehicle detection.

  • 9. Anti-crosstalk interference.
    • Through the dip Switch, the frequency of the loop detector can be adjusted to prevent crosstalk interference caused by the installation of two loop coils too close.

Indicates And Switch

❀Power Led: RED Power LED Indicates “Power ON”

  • CH1 Detecting Led:Continuously On: Indicates vehicle detection.

  • Blinking Slowly: Indicates loop is short circuit or the number of twists after the loop is not enough.

  • Blinking Fast: Indicates loop is open circuit or too many twists after the loop.

  • CH2 Detecting Led:Continuously On: Indicates vehicle detection.

  • Blinking Slowly: Indicates loop is short circuit or the number of twists after the loop is not enough.

  • Blinking Fast: Indicates loop is open circuit or too many twists after the loop.


❀Sensitivity Selection

  • Sensitivity and frequency of the loop can be adjusted by 7-way dip switch and 10-way dip switch setting.

  • User can select 8 different setting by changing the setting of the dip-switch to different modes as in the dip-switch setting tables below. Dip switch 6, 7 and 8 for CH1 sensitivity selection with 0.8 being the least sensitive and 0.015 being the most sensitive.

  • Dip switch 3, 4 and 5 for CH2 sensitivity selection with 0.8 being the least sensitive and 0.015 being the most sensitive.
