The JUTAI W4G Series Controller is an industrial-grade intelligent core device tailored for smart parking and access control systems. It solves the pain point of 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Critical Access Control Points: Ideal for scenarios where network failure is unacceptable, such as government facilities, data centers, and military bases.
- 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.
