Thermal Imaging and understanding Temperature Anomalies

Thermal imaging is one of the most objective and scientifically grounded methods used in paranormal research. It detects infrared radiation (heat) and translates it into a visual temperature map, allowing investigators to observe subtle changes in surface or air temperature that are invisible to the naked eye.
Unexplained “cold spots” or localized temperature drops are often cited as indicators of paranormal activity — but to use this technology effectively, it’s vital to understand its scientific principles, limitations, and best practices for data capture and analysis.

What Thermal Imaging Measures

Thermal cameras detect infrared radiation emitted by objects and surfaces. Every material emits some level of IR energy based on its temperature — this is known as emissivity.

High emissivity (e.g., human skin, fabric): Emits IR consistently, easy to measure.
Low emissivity (e.g., metal, glass): Reflects IR energy, leading to false readings.

Understanding emissivity is essential when interpreting thermal images. What appears as a “cold spot” might simply be a reflective surface or air current, not a genuine temperature anomaly.

Common Causes of Cold Spots

Before attributing a cold spot to paranormal causes, eliminate these common explanations:

Drafts or Ventilation: Air conditioning, open windows, or unseen vents.
Structural Features: Thin walls, damp patches, or uninsulated materials.
Human Movement: Investigators themselves can alter airflow and heat distribution.
Thermal Reflection: Shiny surfaces reflecting cooler or warmer objects nearby.

Proper environmental control and documentation help separate natural temperature variations from potential anomalies.

Recommended Equipment

Thermal Cameras

Use a calibrated, high-sensitivity thermal imager capable of detecting small temperature differences (≤ 0.1°C).

Reliable models include:

FLIR E8 Pro / FLIR ONE Edge Pro – Compact, high-resolution, excellent emissivity control.
Seek Thermal Reveal Pro – Portable and cost-effective with precise spot temperature readout.
HIKMicro B-Series – Reliable imaging with built-in analysis tools.

Always calibrate devices before use, and avoid low-end cameras with limited dynamic range or inaccurate color mapping.

Accessories

Tripods: Keep cameras steady for accurate comparison shots.
Laser Thermometers: Use as spot verifiers alongside the main imager.
Environmental Sensors: Record humidity, airflow, and ambient temperature for context.

Field Methods

1. Baseline Scanning

Before any investigation, take baseline temperature readings of each area. Document all known heat sources such as lights, vents, and electronics.

2. Static Observation

Thermal anomalies are best detected from a fixed position. Set up the camera on a tripod and let it record passively. Movement introduces distortion and airflow.

3. Controlled Environment

Close doors and windows, and note any participants entering or leaving. Even body heat can alter room temperature over time.

4. Repetition and Verification

If a cold spot appears, return to the same location under similar conditions. If it cannot be repeated after environmental stabilization, document it as an anomaly — not yet paranormal, but noteworthy.

Interpreting Thermal Data

Cold Spots: Indicate areas with lower surface temperature; verify using multiple frames to confirm persistence.
Transient Changes: A sudden temperature shift that dissipates quickly often signals airflow or convection, not a supernatural event.
Shape and Edges: Paranormal “cold spots” are sometimes described as irregular, human-sized zones with soft edges; natural sources usually have defined geometric borders.

Use thermal analysis software (e.g., FLIR Tools or ThermApp Viewer) to compare readings across frames and note timestamps for correlation with other instruments (EMF meters, EVP sessions, etc.).

Data Review and Editing

Software Tools

FLIR Tools / ResearchIR: For temperature mapping, emissivity correction, and time-lapse comparison.
ThermApp Analyzer: Great for viewing side-by-side stills and highlighting anomalies.

Processing Guidelines

Preserve the original capture. Never overwrite or alter primary data.
Apply consistent color palettes (e.g., Ironbow, Rainbow, or Grayscale) for comparison.
Annotate with timestamps and sensor data for credibility.
Avoid artificial enhancement that exaggerates contrast or misrepresents temperature scale.

Scientific Context

Thermal imaging is grounded in physics, not mysticism. True temperature anomalies can be measured, reproduced, and analysed objectively. However, thermal variance alone is not proof of paranormal activity. It should always be cross-referenced with other data sources such as EMF fluctuations, EVP captures, or motion sensors. Environmental monitoring, control experiments, and critical thinking are the foundation of credible investigation work.
