**1. Imaging of Surveillance Cameras**   The spectral power distribution with a central wavelength of 830 to 950nm and a half-peak bandwidth of around 40nm falls within the near-infrared spectrum, which is within the perceptible range of standard CCD and CMOS sensors. Consequently, real-time monitoring is possible both during the day and at night. As any object above absolute zero (-273°C) emits infrared radiation, CCD or CMOS sensors can detect both visible and infrared light during the day. Based on the principles of light refraction, longer wavelengths exhibit smaller refractive indices, while shorter wavelengths exhibit larger...
