Thermal Imaging Basic Parameters
Infrared Resolution: 640*480
Super Resolution (SR): Enhanced to 1280*960
Detector Type: Uncooled Infrared Focal Plane Array (IRFPA)
Thermal Sensitivity (NETD): <30mK @ 30℃
（Note: NETD stands for "Noise Equivalent Temperature Difference", a key indicator of thermal imaging device sensitivity; the smaller the value, the stronger the ability to distinguish subtle temperature differences.）
Pixel Pitch: 17μm
Response Bandwidth: 7~14μm
（Note: This range belongs to the "long-wave infrared" band, suitable for detecting thermal radiation of most objects at room temperature and with strong penetration of smoke/fog.）
Image Frame Rate: 30Hz
Lens Field of View (FOV): 25° * 19°
Instantaneous Field of View (IFOV): 0.68 mrad
（Note: IFOV represents the smallest spatial range that a single pixel can detect; the smaller the value, the higher the spatial resolution.）
Minimum Imaging Distance: 0.25m
Lens Focal Length: 25mm
Focus Mode: Auto Focus, Manual Focus
Acoustic Imaging Basic Parameters
Microphone Channels: 162 MEMS Digital Microphones
（Note: MEMS stands for "Micro-Electro-Mechanical Systems"; MEMS digital microphones feature small size, high sensitivity, and stable performance, suitable for acoustic array imaging.）
Acoustic Image Field of View (FOV): 66° * 52°
Positioning Error: <0.05m @ 1m, 40kHz
Lateral Resolution: <0.45m @ 1m, 40kHz
Main Lobe to Side Lobe Suppression Ratio: >10dB @ 40kHz
（Note: This ratio reflects the ability of the acoustic array to distinguish the main sound source from interference; a higher value means stronger anti-interference capability.）
Sound Sampling Rate: 200kHz
Acoustic Refresh Rate: 25Hz
Working Distance: 0.3~100m
