Optoprecise GW-T100 Dual-Spectrum Infrared & Visible Light Imaging System

Overview

The Optoprecise GW-T100 Dual-Spectrum Imaging System is a ruggedized, dual-channel electro-optical surveillance platform engineered for persistent all-weather, day/night situational awareness. It integrates a high-sensitivity uncooled long-wave infrared (LWIR) thermal imager with a high-resolution visible-light camera on a precision dual-axis gyro-stabilized pan-tilt unit. The system operates on the principle of passive infrared radiation detection—capturing emitted thermal energy in the 7.5–13.5 µm atmospheric transmission window—and fuses it with visible-band imagery via real-time hardware-level synchronization. This dual-spectrum architecture enables reliable target detection, recognition, and tracking under conditions where conventional optics fail: total darkness, obscurants (fog, smoke, dust), glare, and low-contrast natural environments. Designed for fixed-site perimeter monitoring, mobile mast deployment, and vehicle-mounted tactical observation, the GW-T100 meets the operational requirements of critical infrastructure protection, border surveillance, search-and-rescue coordination, and law enforcement evidence-gathering missions.

Key Features

• High-fidelity LWIR imaging using a 640 × 512 vanadium oxide (VOx) microbolometer focal plane array with 17 µm pixel pitch and NETD < 50 mK @ f/1.0—ensuring fine thermal contrast resolution across extended ranges.
• Continuous 20–100 mm motorized infrared zoom lens (35× optical equivalent) with calibrated field-of-view ranging from 30.4° × 24.5° (wide) to 6.2° × 5.0° (narrow), supporting both wide-area scanning and long-range identification tasks.
• Dual-spectrum visible channel featuring a 2.1 MP progressive-scan 1/2.8″ CMOS sensor, delivering full HD 1920 × 1280 video at 25 fps with ultra-low-light performance down to 0.0001 lux in monochrome mode.
• 35× optical zoom visible lens (6–210 mm) with motorized focus and auto-iris control, enabling precise daylight magnification and seamless cross-spectrum cueing.
• Dual-axis gyroscopic stabilization subsystem with ≤ 0.1° angular hold accuracy—effectively isolating image motion caused by platform vibration, wind load, or mechanical slew.
• Full-mobility pan-tilt mechanism: continuous 360° azimuth rotation and ±90° elevation range, with maximum slew speeds of 100°/s (pan) and 60°/s (tilt), programmable preset positions, auto-scan patterns, and dwell-time scheduling.
• Integrated hardware-based image fusion engine supporting picture-in-picture (PiP), side-by-side, and alpha-blended display modes for operator-assisted decision making.

Sample Compatibility & Compliance

The GW-T100 is designed for outdoor deployment in uncontrolled environmental conditions. Its IP66-rated enclosure ensures protection against dust ingress and powerful water jets. Operational temperature tolerance spans −30°C to +60°C, with storage capability from −40°C to +70°C and humidity resilience up to 95% non-condensing. All optical surfaces feature anti-reflective and hydrophobic coatings optimized for LWIR transmission and visible clarity. The system complies with IEC 60950-1 (safety), EN 61000-6-2/-6-4 (EMC immunity/emission), and RoHS Directive 2011/65/EU. Optional laser rangefinder modules conform to IEC 60825-1:2014 Class 1M eye-safety standards at 1.54 µm. Firmware and control protocols support audit-ready logging per ISO/IEC 17025-aligned operational procedures, and optional time-stamped metadata embedding facilitates chain-of-custody documentation for evidentiary use.

Software & Data Management

The GW-T100 supports native integration into industry-standard VMS platforms (e.g., Milestone XProtect, Genetec Security Center) via ONVIF Profile S and Profile T compliance. Embedded firmware provides RESTful API access for remote configuration, real-time telemetry polling (temperature, voltage, gimbal status), and event-triggered recording. Video streams are encoded in H.264/H.265 with configurable bitrates and GOP structures; metadata—including GPS coordinates (when externally synchronized), timestamp (NTP or PTP v2), and sensor state—is embedded in SDI and RTSP streams. Optional SDK enables custom GUI development, multi-sensor correlation logic, and integration with GIS or command-and-control dashboards. All firmware updates are digitally signed and validated prior to installation to ensure integrity and traceability.

Applications

• Perimeter security for power substations, oil & gas facilities, and transportation hubs—detecting intrusions through vegetation, terrain masking, or adverse weather without active illumination.
• Maritime domain awareness: vessel classification, small-craft detection, and SAR coordination in coastal fog or nighttime operations.
• Wildlife monitoring and anti-poaching patrols: non-invasive observation of nocturnal fauna and human activity in dense forest or desert environments.
• Firefighting support: identifying hotspots behind smoke layers, locating trapped personnel via thermal signatures, and assessing structural integrity during overhaul.
• Tactical law enforcement: covert surveillance, suspect tracking, and forensic scene documentation under low-visibility conditions while maintaining evidentiary admissibility.

FAQ

Does the GW-T100 support integration with third-party video management systems?
Yes—it conforms to ONVIF Profiles S and T, enabling plug-and-play compatibility with major VMS platforms including Milestone, Genetec, Avigilon, and Bosch BVMS.
Is the thermal imaging calibrated for quantitative temperature measurement?
No—the GW-T100 is optimized for qualitative detection, recognition, and tracking. It does not include radiometric calibration or emissivity correction; therefore, it is not intended for absolute temperature reporting per ASTM E1933 or ISO 18434-1.
Can the system operate autonomously without continuous network connectivity?
Yes—local SD card recording (up to 256 GB) and onboard event-triggered storage allow fully offline operation. Network connectivity is required only for remote control, live streaming, or centralized analytics.
What mounting options are available for fixed-site installations?
Standard M36×1.5 base flange with integrated cable gland entry; compatible with pole mounts, wall brackets, and seismic-rated pedestals per IBC 2018 Appendix A.
Is firmware update functionality accessible via web interface or only through serial connection?
Both methods are supported: secure HTTPS-based web UI for routine updates and CLI access via RS-422 for field recovery and diagnostic purposes.
