Ethernet Thermal Advanced Driving Assistance System

LWIR Uncooled Microbolometer — The Core Detection Technology

The module incorporates an uncooled LWIR microbolometer sensor that detects infrared radiation in the 8–14 μm spectrum, converting heat signatures into thermal video. Microbolometer sensors measure the temperature-dependent resistance change of an array of tiny heat-sensitive elements — one per pixel — when infrared radiation from the scene is absorbed. ‘Uncooled’ means the detector array operates at ambient temperature without the cryogenic cooling required by photon detectors (such as the InSb detector in the GIS-320 gas camera), making the module compact, low-power, and maintenance-free while achieving the <50 mK NETD sensitivity suited to the majority of thermal surveillance, monitoring, and ADAS applications.

The 640 × 480 px array with ~17 μm pixel pitch provides VGA-format thermal imaging with sufficient spatial resolution for human detection and characterisation, vehicle identification, industrial equipment monitoring, and building thermal assessment at the working distances typical of security camera, ADAS sensor, and industrial monitor deployments.

ONVIF Compliance — Plug-and-Play IP Network Integration

With a network-ready Ethernet interface supporting ONVIF and standard streaming protocols, the module can broadcast thermal data, integrate directly with network video recorders (NVR), and communicate with VMS or automation systems. ONVIF (Open Network Video Interface Forum) is the open industry standard that governs how IP cameras and network video systems discover each other and exchange commands — an ONVIF-compliant camera can be added to any ONVIF-compatible VMS or NVR without custom integration development. This means the Ethernet thermal module integrates into existing IP security infrastructure alongside standard visible-light IP cameras using the same VMS administrator workflow used to add any network camera, with no camera-specific driver or SDK required for basic streaming and management.

Network-Ready Ethernet Connectivity with ONVIF

Featuring a standard RJ-45 Ethernet interface with ONVIF support, this thermal imaging module integrates easily into IP-based surveillance and automation networks. Real-time thermal streams can be viewed, recorded, and analysed over LAN or WAN without additional conversion hardware. ONVIF compliance ensures interoperability with major VMS platforms (Milestone, Genetec, Hikvision, Dahua) and NVR brands used across Indian corporate, government, and industrial security installations.

High Thermal Resolution — 640×480 px with <50 mK Sensitivity

The 640 × 480 pixel LWIR detector captures detailed thermal patterns, while thermal sensitivity below 50 mK enables detection of fine heat deviations — essential for early fault detection in electrical equipment, perimeter intruder detection at long range, ADAS pedestrian detection in darkness and fog, and process monitoring of low-contrast industrial scenes.

ONVIF Compliance for Broad VMS and NVR Compatibility

ONVIF support ensures interoperability with major video management systems, network video recorders, and security platforms, enabling seamless integration into enterprise network environments without custom driver development. The module appears in ONVIF-compatible VMS discovery alongside standard IP cameras and is managed using the same administrator interface.

Advanced On-Board Image Processing

The module enhances raw thermal data using automatic gain and contrast control, spatial and temporal noise filtering, and multiple colour palettes. These features improve scene clarity in low-contrast or high-dynamic-range environments, ensuring the transmitted video stream is optimised for operator interpretation and automated analytics without requiring host-side processing.

Flexible Frame Rates — 9 Hz, 30 Hz, 60 Hz

Selectable frame rates allow the module to suit sensor bandwidth requirements, regulatory needs, or real-time streaming strategies, making it adaptable to region-specific constraints and application demands. 9 Hz for internationally distributable configurations, 30 Hz for smooth monitoring, 60 Hz for dynamic event capture.

Compact and Lightweight — ~40×38×45 mm, <85 g

With compact dimensions and a lightweight build, the module can be embedded into custom enclosures, robotic systems, industrial equipment, vehicle-mounted sensor housings, and distributed sensor nodes without significant payload or space constraints. The small footprint and single RJ-45 + power cable connection simplify mechanical and electrical OEM integration.

Rapid Start-Up and PoE Option

A startup time of less than 5 seconds supports efficient deployment and minimal delay in operational readiness — ideal for on-demand systems, emergency response deployments, and continuously monitored installations where the module may cycle power periodically. Optional PoE simplifies wiring in distributed network installations by delivering power and data over a single Ethernet cable.

Networked Security and Perimeter Monitoring

In security systems, the Ethernet thermal module provides 24/7 thermal visibility without dependency on visible light. Integrated over IP networks, it supports centralised monitoring, automated alerts, and high-contrast detection regardless of lighting, fog, or smoke conditions:

• Perimeter intrusion detection: human and vehicle detection at facility perimeters in total darkness, fog, or smoke where visible-light cameras provide no useful image, integrated via ONVIF into existing IP-CCTV VMS infrastructure
• Critical infrastructure protection: thermal monitoring of power substations, data centres, water treatment plants, and fuel storage facilities for both intruder detection and thermal anomaly (fire risk) alerting from a single camera stream
• Border and coastal surveillance: thermal detection of unauthorised crossings at border and coastal areas in all weather and lighting conditions, streamed over IP networks to remote monitoring centres

Smart Industrial Automation and Facility Management

Industries use thermal imaging to monitor machine health, detect electrical hotspots, and maintain production equipment. The Ethernet interface allows centralised remote thermal monitoring across factory floors:

• Electrical equipment thermal monitoring: continuous IP-networked thermal monitoring of MCC panels, busbar connections, transformer terminations, and switchgear for early fault detection, integrated with existing SCADA or BMS systems via ONVIF or RTSP stream
• Machine health monitoring: factory-floor distributed thermal monitoring of rotating machinery, conveyor drives, and process equipment for overheating detection, integrated with maintenance management systems
• Process and quality monitoring: inline thermal monitoring of production processes over the facility IP network, enabling remote thermal process observation from the control room

Building and Infrastructure Monitoring

For smart building solutions, thermal data streamed over networks identifies insulation issues, HVAC inefficiencies, or moisture intrusion. Facility managers use this to optimise energy use and prevent structural issues:

• Building envelope thermal assessment: IP-networked thermal scanning of building envelopes for insulation deficiency and moisture infiltration, integrated with BMS energy management systems via ONVIF
• HVAC system monitoring: thermal monitoring of AHU, chiller, and duct system components for performance assessment and fault detection in commercial and industrial building management
• Data centre thermal management: distributed thermal monitoring of server rack hot aisles, cooling unit performance, and floor tile airflow for data centre cooling efficiency and equipment protection

Remote Environmental and Utility Surveillance

Distributed thermal modules with Ethernet connectivity are ideal for monitoring critical infrastructure like pipelines, transmission lines, or environmental conditions:

• Remote pipeline thermal monitoring: fixed thermal cameras at pipeline valve stations, compressor sites, and pig trap areas providing continuous IP-networked thermal imaging for leak detection and equipment condition monitoring
• Transmission line and substation remote monitoring: thermal cameras at unmanned substation and transmission line locations streaming thermal data over IP networks to centralised grid operations centres for predictive maintenance
• Environmental monitoring nodes: distributed IP-networked thermal sensors for environmental temperature monitoring, wildlife thermal detection, and ecological research data collection
