right i scoped it out after work but forgot my digi cam. im pretty sure that camera has been there for at least 6 months...
anyway it was a truvelo as correctly pointed out by recalluk. I looked closely and saw two circular 'peepholes' as opposed to the squares on the gatso. however it looked exactly like one. no blue livery as per truvelo
also no markings from what i could see but ill double check this for my peace of mind.
on the link that was posted above it says:
To avoid the 'flash' which is given out by a rear facing Gatso camera the Truvelo system uses an infra red flash which produces no visible 'flash' to the approaching driver. These rely on 3 white-lines in the road, painted just before the camera, and are triggered by strips in the road, used to gain the vehicles speed.
i did see bright flashes thats why i knew i had been flashed!!! maybe once or twice in quick succession! WTF?!
