Product Description
W4G 4G LTE & Ethernet Dual Network Parking Controller with Auto Failover
The JUTAI W4G Series Controller is an industrial-grade intelligent core device tailored for smart parking and access control systems. It solves traditional systems relying on physical lines by integrating 4G LTE and Ethernet dual-network redundancy, realizing automatic failover and seamless connectivity. Equipped with a high-speed ARM Cortex-M3 processor, rich interfaces, and offline operation capabilities, it serves as a reliable "central hub" for communication between cloud platforms, on-site devices (cameras, barriers, detectors), and peripheral equipment—ensuring 24/7 stable operation of parking lots, gated communities, and industrial access scenarios.

Key Functional Advantages
1. Dual-Network Redundancy & Auto Failover
- No network downtime: Automatically switches between Ethernet and 4G networks. If physical lines are damaged or Ethernet fails, it instantly switches to 4G to ensure continuous system operation.
- Cost optimization: Reverts to Ethernet when the network is restored, minimizing 4G data consumption and reducing operational costs.
- Stable signal guarantee: 4G module supports mobile phone network coverage, ensuring normal operation as long as the mobile signal is available.
2. Comprehensive Device Integration Hub
- Camera integration: Directly connects to mainstream LPR cameras via Ethernet (receives photo pushes) or RS485 (obtains license plate data), eliminating the need for additional converters.
- Peripheral control: Controls barriers, lights, and printers via relays; reads vehicle presence from loop detectors via IO inputs; connects card readers via Wiegand interfaces.
- Extended compatibility: Supports ETC reader parsing protocols and LCD display control, adapting to diverse parking lot functional requirements.
3. Offline Operation & Data Integrity
- Independent work capability: Built-in RTC and large-capacity memory, enabling normal operation with pre-stored whitelists and configurations even without network connectivity.
- Offline data storage: Saves license plate recognition records, access logs, and images locally, with up to 64 small-size image storage capacity.
- Automatic sync: Uploads all offline data and images to the cloud immediately after network recovery, ensuring complete audit trails and no data loss.
4. Standardized Cloud Integration (MQTT)
- Simple docking: Uses JSON-over-MQTT protocol for communication, supporting custom or third-party platform integration with provided SDK.
- Full-event coverage: Reports device heartbeat, license plate recognition, QR code scans, and IO status changes; supports remote commands for barrier control, display messaging, and whitelist updates.
- Secure and reliable: QoS 1 communication quality ensures message delivery, with GBK encoding for stable data transmission.
5. Industrial-Grade Reliability & Easy Maintenance
- Harsh environment adaptation: Operates stably in -40°C ~ +85°C extreme temperatures, with ESD and pulse protection for interfaces.
- Low maintenance cost: Remote monitoring of device status (signal strength, temperature, data usage) and firmware updates reduce on-site visits.
- Robust hardware design: Reverse connection protection, overcurrent protection, and durable components ensure 24/7 continuous operation.
Application Scenarios
- Smart Parking Lots & Garages: Serves as the core controller for entry/exit stations, integrating LPR cameras, barrier control, and payment system linkage. Offline operation guarantees uninterrupted service during network outages.
- Gated Communities & Residential Complexes: Manages resident whitelists, visitor temporary access, and delivery vehicle entry/exit. Dual-network redundancy ensures no access control failures.
- Commercial & Retail Parking: Facilitates paid parking, monthly pass management, and integration with QR code payment stations. Reliable operation enhances customer experience during peak hours.
- Industrial & Logistics Parks: Controls truck and authorized personnel access, logs entry/exit times, and integrates with warehouse management systems. Resists harsh industrial environments.
- Toll Stations & Highway Access: Supports ETC protocol integration, with dual-network guarantee for critical communication in toll collection scenarios.
Why Choose W4G Dual Network Parking Controller?
- Eliminates Single Point of Failure: Auto failover between Ethernet and 4G ensures 100% system uptime, protecting revenue and security.
- Simplifies System Architecture: Integrates multiple communication interfaces and control logic, replacing separate network switches, 4G routers, and PC-based software.
- Future-Proof & Scalable: Open MQTT protocol and standard interfaces support integration into IoT platforms, scaling across multiple sites.
- Cost-Effective Operation: Offline data storage reduces real-time network dependency; automatic network switching optimizes data costs.
- Proven Compatibility: Works with mainstream LPR cameras, ETC readers, and peripherals, reducing integration risks for system integrators.
