I get asked about license plate recognition all the
time. With the newer high definition
megapixel network cameras it has become easier to achieve. It is all about pixels per foot. The more pixels on the object the more likely
you are to capture a license plate.
A minimum of 45 pixels per foot are required to be able to
capture a license plate. This is measured
in the horizontal field of view. Meaning
the correct camera and lens combination is required to capture a license
plate. 
These pictures are captured with an Arecont 5 megapixel day
night camera which is recorded to an exacqVision network video recorder.
We at Protection Plus Security Services are experts in video
surveillance systems and have installed numerous high definition video
surveillance systems for our customers.
