High sensitivity and resolution: Cooled detector with low noise, thermal sensitivity (NETD) <20mK, and excellent detail resolution;?
Strong atmospheric penetration: MWIR has high transmittance in specific atmospheric windows (e.g., 3-5 μm), and is suitable for long-distance observation because it is less affected by interference from fog, smoke and soot.

Low sensitivity: usually 30~50mK, lower than cooling type (<20mK), weak detail resolution, easy to overexpose high-temperature targets (need dynamic range adjustment).
Slow response speed: frame rate is usually ≤60Hz, not suitable for ultra-high-speed dynamic scenes (such as ballistic tracking).
