In February, police in Knowlsey secured the first detection in the country using footage from the 'video badges' when they traced a 16-year-old student from Huyton who had racially abused a local shopkeeper.
The incident was captured by the camera, which was being worn around the shopkeeper's neck, and within days the offender's face had been circulated among local police officers.
A school liaison officer recognised him and his parents were informed.
The boy initially denied having been part of the group that had been in the shop but when he and his mother were shown the footage.

A convicted murderer who stabbed a blind man to death has been arrested in Oldham after going on the run from prison.
Arnold Pickering was arrested for being unlawfully at large at an address in Oldham, police said.
The 44-year-old, who was jailed for life in 1991 for killing a man he wrongly thought to be a paedophile, failed to return to HMP Kennet in Merseyside after leaving the Category C jail on day release on Saturday.
Merseyside Police said he was arrested by officers from Greater Manchester Police and is now in custody.
Greater Manchester Police have arrested a 44-year-old man for being unlawfully at large. The man was arrested at an address in Oldham at around 11.45am and is now in custody.
The UK has come to "care more about the human rights of murderers" than the victims bereaved relatives, according to a Conservative MP.
Philip Davies raised concerns that letting convicted criminals out on day release was not transparent enough and violent criminals were kept in prisons lacking the kind of security needed to keep them behind bars.
He told Good Morning Britain: "It seems the human rights of murderers seem more important than those of the victims and the law abiding citizens."

Pickering had been risk assessed as suitable for temporary release on licence by the Ministry of Justice, said Merseyside Police.
