A: When selecting the resolution of a thermal imaging module, factors such as application scenario, detection requirements, budget, and technical limitations should be considered comprehensively.

Medium resolution is suitable for applications such as nighttime perimeter surveillance, medical temperature screening, and search and rescue in fire scenes.

High resolution is recommended for industrial diagnostics, equipment fault detection, and scientific material analysis.

A: Uncooled Detectors: Based on thermistor effect (e.g., VOx, a-Si microbolometers), they absorb infrared radiation to alter resistance values without requiring active cooling .Operating in the 8–14 µm wavelength range, it features compact size and low power consumption, making it ideal for perimeter security, night surveillance, and vehicle-mounted night vision systems.

Cooled Detectors: Based on photon effects (e.g., HgCdTe, quantum wells), they require cryogenic cooling (typically -196°C to -80°C) to reduce thermal noise, achieving higher sensitivity and longer detection range. They are widely used in high-end applications such as defense, aerospace, and scientific research. However, compared with uncooled detectors, they have larger size and power consumption.

Frame rate affects image smoothness and dynamic target capture capabilities:
A: Uncooled cores: Typically 25–50Hz, suitable for general surveillance and low-speed motion scenes.
Cooled cores: Typically 30–120Hz, ideal for tracking high-speed targets.
Application advice: Use high frame rates for aerial imaging or fast-moving targets. For static temperature measurement or slow observation, lower frame rates reduce power consumption.
