Capture zone

- Wide angle provides shorter capture distance and increased capture angle,

but could result in the better image quality and stability.

- Tele angle provides longer capture distance and reduced capture angle,

but could result in reduced image quality and stability.

- While a license plate can still be read by human eye, license plate

capture software might not be able to recognize it.
