Police using high-tech number plate scanners have arrested 140 people and seized drugs and stolen cars worth tens of thousands of pounds.
Officers have operated Automatic Number Plate Recognition (ANPR) vans across East and West Sussex over the past 13 weeks.
A Sussex Police spokeswoman said the focus had been on catching 'real criminals', including street drug dealers and travelling burglars.
The system, which uses technology similar to the congestion charging scheme, scans number plates and matches them to a database.
Stolen or suspect vehicles are flagged up to police, who can then make targeted stops and inquiries.
Sergeant Steve Black, of the ANPR unit, said: "What we have achieved far exceeds what we hoped.
"As well as the 140 arrests, we have recovered £56,000 worth of stolen cars, £31,500 of drugs have been seized and we have gathered intelligence on serious criminals.
"In a nutshell, 85% of the ANPR team's work is on people who are criminally active or have criminal records and we've targeted street drug dealers on foot and cycle, drugs houses and travelling burglars."
Sgt Black said the scanners had helped catch people who were already wanted by the police as well as those driving while disqualified.
"Because we have been casting a large net it also brought all sorts of other things to the surface, involving people at all levels of criminality.
"Our ultimate aim is to drive criminals from the use of the roads."
