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.

Reset Button: Please note: The LD-200 must be reset every time a
setting change is made to the Dip switches.
Loop Installation
The loops are sealed using a “quick-set” black epoxy compound or
hot bitumen mastic to blend with the roadway surface.
When installation, please keep the product plug and socket in the
vertical direction
