Ethernet Thermal Imaging Camera Module

Standard Interfaces — Why RTSP, MJPEG, and ONVIF Accelerate OEM Development

The module’s standard RTSP/MJPEG video streaming and HTTP/ONVIF control interfaces are the key enablers for rapid OEM integration. In embedded product development, the choice between a proprietary-interface camera and a standard-interface camera is a fundamental architectural decision that affects the development timeline, software maintainability, and platform portability of the OEM product. A proprietary-interface camera requires a custom driver or SDK for the specific camera’s binary protocol — increasing development time, creating a vendor-lock dependency, and requiring re-qualification if the camera model changes. A standard-interface camera (RTSP for video, HTTP/ONVIF for control) is accessed using mature, well-documented, openly available libraries that the OEM development team is already using for other components — OpenCV, GStreamer, FFmpeg on Linux; DirectShow on Windows; standard ROS camera nodes on robotic platforms. The thermal module appears in the development environment as a standard network camera, integrating with the same code that handles other IP sensors without any camera-specific development.

OEM Integration Workflow — From Module to Product

The typical OEM integration workflow for this module is: (1) mechanical integration — mount the 40×38×45 mm module in the product enclosure with the appropriate lens facing the monitored scene; (2) power connection — connect 12V DC from the product’s internal power supply, or use PoE from a compatible network switch if the product architecture includes Ethernet switching; (3) network connection — connect the RJ-45 to the product’s embedded computer Ethernet port or switch; (4) software integration — configure the product’s application software to receive the RTSP thermal stream using OpenCV VideoCapture, GStreamer, or FFmpeg with the module’s RTSP URL; (5) remote configuration — configure gain control mode, colour palette, frame rate, and network settings via HTTP or ONVIF API from the product’s configuration interface without physical access to the module. This workflow requires no camera-specific SDK installation and no binary driver deployment, significantly reducing integration complexity and time-to-market.

Standard Ethernet Interface — Framework-Agnostic OEM Integration

Standard RJ-45 Ethernet with ONVIF, MJPEG, and RTSP integrates with any host processor equipped with an Ethernet port — ARM SoCs, x86 embedded computers, industrial controllers, Raspberry Pi, NVIDIA Jetson, and others — using OpenCV, GStreamer, FFmpeg, or ROS standard camera libraries without custom driver development or vendor-specific SDK installation.

640×480 px Resolution with <50 mK Sensitivity

VGA-format thermal resolution at <50 mK NETD provides the spatial detail and thermal sensitivity needed for human detection and characterisation, vehicle identification, industrial equipment monitoring, and building thermal assessment at OEM product working distances. The ~17 μm pixel pitch enables compact, diffraction-limited lens designs suitable for the small form factor of OEM embedded systems.

Compact ~40×38×45 mm, <85 g Embeddable Form Factor

The compact dimensions and light weight enable embedding into custom enclosures, robotic chassis, vehicle-mounted sensor housings, UAV payloads, and distributed sensor nodes without structural modification to the host product. The single RJ-45 cable connection (carrying data and optionally PoE power) minimises connector count and wiring complexity within the OEM product assembly.

On-Board Processing — Zero Host-Side Thermal Processing Burden

On-board automatic gain control, spatial and temporal noise filtering, and colour palette application deliver an optimised thermal video stream to the host application without requiring the OEM host processor to perform thermal image processing. The host application receives a ready-to-display and ready-to-analyse MJPEG/RTSP video stream, reserving the host processor’s compute budget for the OEM product’s own application logic rather than thermal sensor signal processing.

Flexible Frame Rates and PoE for OEM Architecture Flexibility

Selectable 9/30/60 Hz frame rates and optional PoE power delivery provide the OEM designer with configuration flexibility to match the product’s performance requirements, regulatory environment, and power architecture. PoE eliminates a separate power supply for the thermal module in OEM products where Ethernet is already routed to the camera location, simplifying the product’s internal power distribution design.

Remote Configuration via HTTP/ONVIF — No Physical Access Required

All module parameters — gain control mode, colour palette, frame rate, network settings — are configurable remotely via HTTP API or ONVIF commands from the OEM product’s configuration interface. For modules embedded inside sealed enclosures or integrated into robotic platforms where physical access to the module is impractical, remote configuration enables parameter adjustment through the OEM product’s software interface and firmware update mechanism throughout the product’s deployment lifetime.

Broad Development Framework Compatibility

The standard RTSP stream is receivable by OpenCV VideoCapture, GStreamer, FFmpeg, DirectShow, Media Foundation, and standard ROS camera driver packages — the standard video processing frameworks used across Python, C++, and ROS OEM development environments in India’s robotics and embedded systems industry — without any camera-specific SDK or driver installation.
