For a normal CCTV camera (that is linked to a PC capture card) and on a fine sunny day.
Is there a typical distance you can read a number plate.
With one of the SafeCore CCTV 1/3" SONY Colour WDR & ICR(True Day&Night) Camera (Hi-Res.) cameras 752x582 picture element, 520 lines resolution, 0.1 Lux / F1.2 day, 0.001 Lux / F1.2 at night with IR switching and with effective IR illumination.

1 - Is there a typical distance you can read a number plate. 2 - Would I then be able to read a number plape at say 25m. 3 - What would the picture be like at night with IR on, or are they just too grainy 4 - Or are my problems only due to the PC capture card.
