All public opinion surveys have shown that safety cameras are acceptable if it is made clear that their purpose is to make the roads safer rather than to raise revenue. Camera systems have been operational in the UK since 1989 and, where deployed, have saved lives and reduced accidents. In the UK, the average distance between sites of camera posts is 1.5 km whereas the average distance between fixed-post camera sites in Louth and Meath is 8 km. There are in excess of 3,000 camera sites in the UK, of which approximately 2,000 are used for speed enforcement and 1,000 to monitor traffic light infringements. That demonstrates the belief by the authorities in the UK of the value of these cameras. In contrast, there are only 20 such cameras in Ireland. The 35 mm camera systems employ film cassettes which are capable of capturing 1,000 images and can be processed on a two to three day cycle.
