Reading a vehicle number plate is difficult
for a standard CCTV camera. The main problem is the
exposure caused by headlight at night, but even during
the day the light reflection on the number plate can
make the number recognition virtually impossible. Our
filter can block
CWL means center wavelength, FWHM means full
width at half maximum |
