Product Overview
The HL800 Smart Monitoring System is an enterprise-grade power and environment monitoring platform jointly developed by Nanjing Hongmu Technology and German HELM. Built on a standard 19-inch 1U rack-mount chassis with a TI AM3352 industrial processor running at 800MHz under Linux OS, the HL800 delivers reliable, continuous monitoring for mission-critical facilities including data centers, hospital server rooms, banking IT infrastructure, and laboratory environments.
What sets the HL800 apart from conventional monitoring systems is its highly integrated, modular architecture. All analog and digital sensor inputs are converted to standard RJ45 Ethernet interfaces with built-in POE functionality — communication and 12V power travel through a single network cable. This drastically simplifies wiring, eliminates connection errors, and makes future sensor expansion as easy as plugging in an Ethernet cable. The system supports multiple power configurations (single AC220V, dual AC220V, or AC with lithium battery backup) ensuring uninterrupted monitoring even during power events.
With 256MB DDR3 RAM, 256MB Nand Flash storage, and SD card expansion up to 128GB, the HL800 provides ample local data logging capacity. The system integrates 2x RS232, 3x RS485, and supports Ethernet, Wi-Fi, and 4G communication modules for seamless remote access. Built-in protocol support for UPS and precision air conditioning units means the HL800 can monitor and control power infrastructure and HVAC systems directly, with an easy-to-upgrade firmware interface for new protocol modules.
The HL800 is engineered for 5-10 years of maintenance-free operation, backed by European-certified HELM industrial computing hardware. Paired with custom-developed German monitoring software, the system achieves a level of integration, reliability, and operational intelligence that positions it as a premium choice for organizations that cannot afford monitoring downtime.

Key Features
RJ45 Unified Interface with POE
All analog and digital sensor inputs converted to standard RJ45 Ethernet ports with built-in POE — communication and 12V power through one cable. Clean wiring, easy expansion, zero connection errors.
German HELM Industrial Computing
Powered by European-certified HELM industrial hardware with TI AM3352 processor (800MHz), 256MB DDR3, and Linux OS — engineered for 5-10 years of uninterrupted, maintenance-free operation in harsh environments.
Flexible Power Redundancy
Choose from single AC220V, dual AC220V, or AC with lithium battery backup. Multiple power combinations ensure the monitoring system stays online during mains outages — critical for 24/7 data center operations.
Comprehensive Sensor Integration
Out-of-the-box support for temperature/humidity, smoke, water leak, vibration, tilt, and door access (Bluetooth smart locks + card readers + magnetic contacts) — all in one rack-mount platform with expandable sensor channels.
UPS & Air Conditioning Control
Built-in protocol support for UPS monitoring and precision air conditioning control via 2x RS232 and 3x RS485 interfaces. Monitor battery health, cooling performance, and automate responses — with easy firmware upgrades for new protocol modules.
Multi-Path Remote Access
Connect via Ethernet, Wi-Fi, or 4G cellular — select one or combine multiple paths for redundancy. Touch screen interface provides local status overview, while remote access enables centralized management of distributed sites.
Applications
Enterprise Data Centers
Monitor server room temperature, humidity, smoke, and water leaks while managing UPS battery status and precision air conditioning. The 1U rack form factor integrates directly into existing cabinet infrastructure with minimal footprint.
Banking & Financial IT Rooms
Meet stringent financial sector compliance requirements with comprehensive environmental monitoring, authorized access control via Bluetooth smart locks and card readers, and automated relay responses to emergency conditions like smoke or water intrusion.
Hospital & Healthcare Facilities
Protect critical medical IT infrastructure with 24/7 environmental monitoring. Dual power supply with lithium battery backup ensures uninterrupted surveillance of server rooms housing electronic health records and medical imaging systems.
Utility & Power Grid Control Rooms
Integrate with power grid monitoring systems (e.g., NARI Group platforms) to provide environmental intelligence for substations and control rooms. The HL800’s RS485/RS232 interfaces enable direct connection to existing SCADA infrastructure.
Broadcast & Media Data Centers
Proven in TV station deployments with integration into VR systems and broadcast monitoring displays. Supports automated fire response (skylight actuation, fire system linkage) and water leak emergency power cutoff to prevent short circuits.
Laboratories & Warehouses
Monitor environmental conditions in research laboratories, pharmaceutical storage, and temperature-sensitive warehouses. Relay outputs automate heating, dehumidification, and ventilation responses to maintain optimal storage conditions.
