Workswell TIS 640 Vehicle-Mounted Firefighting & Security Infrared Thermal Imaging System

Overview

The Workswell TIS 640 is a purpose-engineered vehicle-mounted infrared thermal imaging system designed for mission-critical operations in firefighting, civil security, and industrial surveillance environments. Built upon uncooled microbolometer detector technology operating in the long-wave infrared (LWIR) band (7.5–13.5 µm), the TIS 640 delivers high-fidelity thermal radiometry without cryogenic cooling—enabling rapid deployment, low power consumption, and mechanical robustness essential for mobile platforms. Its dual-sensor architecture integrates a 640 × 512 resolution thermal imager with a synchronized 800 × 600 visible-light camera, co-aligned within a single ruggedized housing. This fusion enables real-time overlay, side-by-side comparison, and context-aware interpretation of thermal anomalies against visual landmarks—critical during smoke-obscured fireground navigation, perimeter intrusion assessment, or nocturnal wildlife monitoring.

Key Features

• IP67-rated hermetic enclosure fabricated from germanium (Ge) optical window material—optimized for LWIR transmission, thermal stability, and passive heat dissipation under sustained operation.
• Fixed infinity focus optics with 1–14× continuous digital zoom, enabling scalable situational awareness without mechanical recalibration or focus drift.
• Dual-range temperature measurement capability: selectable low-range mode (0–250 °C) for structural heat mapping and personnel detection; high-range mode (50–1000 °C) for direct flame and hot-spot quantification in active combustion zones.
• Thermal sensitivity (NETD) ≤50 mK ensures reliable detection of subtle thermal gradients—such as latent fire spread behind walls, electrical fault precursors, or body heat signatures at extended standoff distances.
• Integrated pan-tilt-zoom (PTZ) motorized gimbal controlled via CAN bus or RS-485 interface, supporting both cockpit-mounted touchscreen and remote tablet-based operation over Ethernet/Wi-Fi.
• Pre-calibrated factory calibration traceable to NIST-traceable blackbody references; supports field verification using external reference sources per ISO 18434-1 guidelines.

Sample Compatibility & Compliance

The TIS 640 operates independently of sample preparation—acquiring non-contact surface temperature distributions from dynamic, uncooperative, or hazardous targets including burning structures, moving vehicles, wildlife, and perimeter fences. Its optical design complies with EN 62471 (photobiological safety) and meets electromagnetic compatibility requirements per EN 61000-6-2 (immunity) and EN 61000-6-4 (emissions). The system’s firmware and configuration logs support audit-ready data integrity protocols aligned with GLP principles. While not FDA-regulated, its measurement repeatability and calibration documentation are suitable for inclusion in ISO/IEC 17025-accredited laboratory quality management systems where thermal imaging serves as a documented inspection method.

Software & Data Management

Control and visualization are managed through Workswell’s proprietary TIS Control Suite, deployable on Windows-based industrial PCs or Android tablets. The software provides real-time dual-stream video rendering, user-defined measurement regions (spot, line, area), automatic min/max/center temperature readouts, emissivity correction tables, and alarm-triggered image capture. All thermal metadata—including timestamp, GPS coordinates (when integrated), lens parameters, and calibration status—are embedded in standard JPEG/AVI exports. Exported datasets conform to ASTM E1933-19 Annex A1 format for thermographic reporting. Remote firmware updates and configuration backups are supported via secure HTTPS channel, with optional password-protected user roles (operator, technician, administrator) compliant with basic IT security hygiene practices.

Applications

• Fire Service Operations: Rapid identification of hidden fire extension, flashover risk assessment, victim localization through smoke or darkness, and post-fire hotspot verification—reducing exposure time and improving incident command decision latency.
• Civil Security & Border Surveillance: 24/7 perimeter monitoring under total darkness, fog, or light foliage; detection of concealed persons or vehicles based on thermal contrast against ambient terrain.
• Wildlife Ecology Research: Non-invasive nocturnal behavioral observation, population censusing, and thermal signature cataloging across species—without requiring animal handling or artificial illumination.
• Industrial Asset Monitoring: Mobile inspection of electrical substations, pipeline integrity, roofing moisture ingress, and mechanical bearing temperatures during routine patrol routes.

FAQ

Is the TIS 640 certified for use in explosive atmospheres (ATEX/IECEx)?
No—the TIS 640 is not intrinsically safe certified. It is rated for general industrial and emergency response use under IP67 conditions but must be operated outside classified hazardous zones unless installed with additional explosion-proof enclosures meeting local regulatory requirements.
Can the system output radiometric data streams via RTSP or ONVIF?
Yes—thermal and visible video streams are accessible via standard RTSP URLs; ONVIF Profile S compliance is supported for integration into third-party VMS platforms such as Milestone XProtect or Genetec Security Center.
Does the system support external GPS synchronization and geotagging?
Yes—RS-232 or NMEA 0183-compatible GPS receivers can be connected to the control unit; all captured frames include embedded geographic coordinates and UTC timestamps when enabled.
What is the expected operational lifetime of the microbolometer detector?
Workswell specifies ≥10,000 hours of continuous operation under nominal environmental conditions (−10 °C to +50 °C ambient), consistent with industry-standard uncooled VOx microbolometer reliability metrics.
Is firmware update capability available over-the-air (OTA)?
Firmware updates require local connection via Ethernet or USB; OTA functionality is not implemented due to cybersecurity constraints inherent in vehicle-mounted critical infrastructure devices.
