Key Functional Advantages
1. Dual-Network Redundancy & Uninterrupted Operation
  • No line dependency: 4G + Ethernet dual-network design, automatically switching to 4G when physical lines are damaged or Ethernet fails
  • Cost optimization: Reverts to Ethernet after network recovery, minimizing 4G data consumption and operational costs
  • Stable signal coverage: Uses mobile operator networks, ensuring normal operation as long as mobile signals are available
2. Seamless LPR System Integration
  • Direct camera integration: Supports Ethernet photo push from Zhixin/Zhenshi cameras and RS485 license plate data from three mainstream brands
  • Fast data transmission: Ethernet uploads 100KB photos in ~0.5 seconds, 4G in ~1.5 seconds, ensuring real-time LPR processing
  • Fake plate detection: Cooperates with supported cameras to identify fake/return/stay plates, enhancing parking security
3. Offline Operation & Data Integrity
  • Independent work capability: Built-in RTC (power failure backup) and large-capacity memory, operating with pre-stored whitelists offline
  • Offline access control: Automatically allows valid whitelist vehicles to pass, denies temporary/expired vehicles, and saves all records
  • Automatic sync: Uploads offline logs, images, and access records to the cloud immediately after reconnection, no data loss
4. Comprehensive Barrier & Peripheral Control
  • Barrier management: 2 high-load relays control barrier opening/closing/holding open, with LED delay control (1-30 seconds)
  • Peripheral linkage: Reads loop detector signals via IO inputs to sense vehicle presence; connects card readers via Wiegand for dual access control
  • Extended functions: Supports ticket printers, ETC readers, and LCD displays, adapting to diverse parking lot configurations
5. Cloud Integration & Intelligent Management
  • MQTT protocol docking: Standard JSON format, supporting cloud control of barriers, display content, voice broadcasts, and whitelist updates
  • Real-time monitoring: Periodic heartbeat reports (1 minute default) include signal strength, temperature, data usage, and network type
  • Whitelist management: Supports adding/modifying/deleting whitelists (max 16000 entries), with batch operation to extend flash lifespan
Application Scenarios
  • Smart Parking Lots: Core controller for entry/exit stations, integrating LPR recognition, barrier control, and payment system linkage. Offline operation ensures uninterrupted service during network outages
  • Residential Communities: Manages resident whitelists and visitor temporary access, linking with community access control systems for secure vehicle entry
  • Commercial & Retail Parking: Facilitates paid parking, monthly pass management, and QR code payment integration. Dual-network redundancy guarantees peak-hour reliability
  • Industrial Parks & Logistics Centers: Controls truck and authorized personnel access, logs entry/exit times, and integrates with warehouse management systems
  • Highway Toll Stations: Supports ETC protocol integration, with dual-network stability ensuring critical communication in toll collection scenarios
Why Choose W4G 4G Parking Lot Controller?
  • LPR-Specific Optimization: Seamless integration with mainstream LPR cameras, reducing integration complexity for system integrators
  • Zero Downtime Guarantee: Dual-network auto-failover eliminates line-dependent outages, protecting parking lot revenue and security
  • Robust Offline Capability: Independent operation with data storage ensures normal access control even without network connectivity
  • Industrial-Grade Durability: Extreme temperature resistance (-40°C ~ +85°C) and interface protection for harsh outdoor environments
  • Scalable & Future-Proof: Open MQTT protocol and rich interfaces support cloud platform integration and functional expansion
