Multanova cameras hidden in "wheelie bins" behind trees will form part of a two-pronged crackdown on speeding motorcyclists to be announced today. In a bid to end a 'rort' which has seen speeding motorcyclists dodge more than $14 million in fines since 2000, speed cameras will be linked to high-resolution digital video cameras to capture front and rear shots of errant bike riders. Although motorcycles are photographed by speed cameras, police have not been able to prosecute speeding riders because the bikes do not have a front numberplate and cannot be identified. Front numberplates have not been required on motorcycles for more than for 20 years after a coronial finding that a metal plate on a bike had been responsible for decapitating a pedestrian. But an interim measure to be announced today by Police Commissioner Karl O'Callaghan will close the loophole. Under the companion camera plan, a hidden Multanova would photograph the rear registration plate at the same time as the digital video camera records the speeding motorcycle from the front. Police would then cross-reference the still and video images with time codes to correctly identify the bike's registered owner and issue a fine. Speeding car drivers detected by the hidden companion cameras could also be sent an infringement notice. But neither riders nor drivers would know they had been caught speeding because they were unlikely to see a camera flash and the fluorescent signs that tell motorists they have passed a speed camera would not be used. In a further sign of the tough stance police want to take on motorcyclists, who are about 19 times more likely to be killed on WA roads than car drivers, the companion camera sites would not be released to the media for broadcast or publication. Although only one companion camera unit would be used initially at random sites across the metropolitan area, several more could be in use within months. The companion cameras would be used until the start of the repeatedly delayed $7 million Capspeed project and the outcome of a Victorian project to find a suitable front identifier for motorcycles that was safe, durable and detectable by speed cameras. More than three years ago, Police Minister Michelle Roberts first announced an attempt to solve the problem. She posed for a photograph on a WA police motorcycle with a front licence plate sticker similar to those being tested by South Australian police.
