Purpose

The MOBOTIX Thermal Validation App is designed to distinguish real temperature events from reflections, moving heat sources or transient disturbances. It enhances the reliability of Thermal Image Fire Detection (TIFD) in dynamic environments such as recycling plants, waste bunkers, or industrial halls with machinery movement. For a detailed introduction to the functions and general conditions of the MOBOTIX Thermal Validation App, please refer to the corresponding app documentation.

This checklist describes a best-practice simulated acceptance procedure to verify that the app and the TIFD system operate correctly with a suitable radiating reference source under controlled, simulated test conditions.

Preparation

  • Ensure the TIFD system and the MOBOTIX Thermal Validation App are properly configured and active.
  • Prepare a radiating reference source (e.g., blackbody radiator or equivalent) that meets the specified test conditions for accurate temperature measurement (minimum 3×3 pixel spot coverage in the test distance).
  • Set the reference source to remain stable and stationary during the entire test.
  • Note the configured alarm threshold temperature(s) (e.g., 80 °C).

1) Setup

  • Position the reference source within the camera’s field of view but cover it completely so it cannot be detected by the TIFD.
  • Begin the heating process of the reference source, targeting the configured threshold temperature.

2) Partial Exposure

  • As heating begins, partially uncover (≈50%) the reference source so that the TIFD can partially measure its thermal radiation.
  • Continue heating until the measured temperature in the TIFD image reaches the configured threshold (e.g., pre-alarm threshold 80 °C).

3) Learning Phase

  • Once the threshold temperature is reached, keep the setup unchanged for 20–25 seconds to allow the Validation App to analyze the heat signature.
  • During this period, confirm that the app displays a detected temperature spot within the defined measurement area in the TIFD’s live image, indicating that the object is recognized as a relevant hotspot.

4) Growth Simulation

  • After the learning phase, fully uncover the reference source to simulate the natural growth of a hotspot.
  • Observe the TIFD and confirm that the system immediately triggers the configured alarm (visual and/or via output interface).

Expected Results

  • The hotspot is correctly detected and displayed after the learning phase.
  • When the heat signature expands, the Thermal Validation App confirms the event being valid and the TIFD triggers the alarm according to configuration.
  • No false alarms occur during static or partially covered phases.
