Multi function 4G Parking Lot Controller for LPR System & Barrier Control

Core Technical Parameters

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 对接: 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 适应 harsh outdoor environments.
• Scalable & Future-Proof: Open MQTT protocol and rich interfaces support cloud platform integration and functional expansion.
