HADECS 3 speed cameras explained
REDFLEXhadecs3 or HADECS 3 which is short for Highway Agency Digital Enforcement Camera System 3 is one the newest speed cameras to be installed on UK roads.
Following Home Office approval the first Redflex Hadecs 3 system went live on the M25 motorway between junctions 5 and 6/7 on the 22nd October 2014. Between the 22nd October and 25th November 2014 some 668 motorists had been caught speeding by the new speed camera, many of which are calling it a 'stealth camera'.
The Redflex Hadecs3 is being called a so called stealth speed camera by motorists and the media alike because the cameras are very small in size and painted grey rather than bright yellow (a colour that has become synonymous with speed cameras since 2003). This makes the new REDFLEXhadecs3 camera very hard to spot at the road side or within overhead gantries.
