Using the Autel Evo Max4T XE Thermal camera, settings and features

Thermal Camera Features & Spotting Workflows


1. Gimbal-Integrated Thermal Imager

  • Sensor & Resolution
    Uncooled VOx microbolometer captures 640×512 px radiometric video at 25–30 fps and stills with embedded temperature metadata Evo Max Series Manual.

  • Optics & FOV
    61° FOV, 9.1 mm F1.0 lens; focus from 2.2 m to ∞ Evo Max Series Manual.

  • Radiometric Methods
    Supports center-point, spot, and area temperature measurements Evo Max Series Manual.


2. Dual-Sensor Fusion & Ranging

  • Visible + Thermal
    Side-by-side, split-screen, or blended overlay of 50 MP visible and thermal feeds for context.

  • Laser Rangefinder
    905 nm LRF tags temperature readings with precise distance (5–1 200 m) and GPS coordinates Evo Max Series Manual.


3. Switching & Zoom

  • Interface
    Tap the “Thermal” icon to switch to IR view; tap “Zoom” to enter full-screen thermal.

  • Digital & Linked Zoom
    1–16× thermal digital zoom; on zoom-camera gimbals, thermal follows optical zoom up to ~4× .


4. Palettes & Image Enhancement

  • Color Palettes
    White Hot, Black Hot, Ironbow, Rainbow 1/2, Lava, Arctic, Medical, Tint, etc.—“Lava” excels at fire contrast Evo Max Series Manual.

  • Contrast/Brightness
    Manual sliders for image enhancement—higher values sharpen detail in low-contrast scenes Evo Max Series Manual.

  • Defog Mode
    Eliminates haze/smoke for clearer visuals in steam or smog conditions Evo Max Series Manual.


5. Radiometric Measurement Modes

  • High Gain (–20 °C to +150 °C)
    Greater accuracy for subtle temperature differences.

  • Low Gain (0 °C to +550 °C)
    Wide-range capability for extreme-heat scenarios .

  • Flat-Field Calibration (FFC)
    Manual FFC optimizes uniformity before critical inspections Evo Max Series Manual.


6. Temperature Tools & Alarms

  • Spot & Area Meters
    Tap for point readout; drag a box for min/avg/max over a region Evo Max Series Manual.

  • Isotherm Highlighting
    Pre-set bands (Off/Human/Fire/Custom) to mask out all but targets within thresholds Evo Max Series Manual.

  • Temperature Alarm
    Define high/low thresholds; on breach, the system flags value and coords in real time .

  • Emissivity & Reflected Temp
    Fine-tune emissivity (0.01–1.00) and background-reflected values for accurate readings on varied surfaces .


7. Data Capture & Export

  • Radiometric Photos (JPEG + R)
    Stills embed full temperature data for PC/SDK tools.

  • Radiometric Video (MP4)
    Records every frame’s radiometric info for post-mission analysis.

  • In-App Review & Offload
    Tag, preview, and download via Wi-Fi Super Download or microSD.


8. Fire-Spotting Workflow

  1. Warm-Up: Power on and let IR sensor stabilize (~1 min).

  2. Palette: Select “Lava” or “Ironbow.”

  3. Gain Mode: Use Low Gain if >150 °C; otherwise High Gain.

  4. Isotherm: Set lower bound just above ambient to isolate flames.

  5. Alarm: Program high-temp threshold (e.g., 200 °C); monitor flag alerts.

  6. Record: Capture JPEG + R for mapping or video for dynamic fire tracking.


9. Other Spotting Workflows

  • Search & Rescue (SAR)
    Night-vision fusion and high-contrast palettes to pinpoint human heat signatures; spot-meter to verify life signs.

  • Wildlife & Anti-Poaching
    Lava/Arctic palettes reveal animals in dense cover; linked zoom tracks targets at distance.

  • Electrical & Mechanical Inspection
    Area meters and isotherms highlight overheated components; emissivity tuning ensures accuracy on metals/plastics.

  • Building & Leak Detection
    Defog cuts through steam; radiometric photos document insulation gaps or moisture intrusion.

  • Maritime & Vehicle Surveillance
    LRF-tagged thermal readings locate small boats or vehicles at sea; high-mag hybrid zoom identifies distant heat sources.

  • Environmental Monitoring
    Use High/Low Gain modes for soil, water, or volcanic temperature trends; time-stamped radiometric video captures dynamic changes.


This unified guide equips you to leverage the EVO Max’s thermal payload across fire response, SAR, inspection, wildlife patrol, and beyond—unlocking comprehensive radiometric insight in every mission.
