Mr. Cornelius O'Donohue:

We do not have any issues with the technology per se. There are limitations to any piece of technology. With the particular camera and radar system used at present in some cases one cannot proceed with prosecution because of where a second vehicle is in the image. We look at the data behind capturing the image, with regard to what the radar detected, to identify an offending vehicle but it is not always clear. The new technology makes it easier to identify the offending vehicle if two vehicles are in the image. We check all of the images and the data behind them. Radar constantly sends out a signal and receives results which are plotted in a graph we can examine. When we do so we decide whether an image can be let through. This limitation at present does not cause a problem with convictions because we do not let the images concerned through the process. The dual grader will allow more images to come through the validation process and more fixed charge notices will be issued. If two cars are side by side in an image we will have a better chance of identifying an offending vehicle with the new technology. This is slightly more difficult to do at present. Anything which goes through the system is perfectly validated and the new technology will allow us validate more images and approve more fixed charge notices.
