Victorian police will staff a new 24-hour help line and have the power to collect DNA samples from suspects without a court order, as the Andrews Government strives to curb the state's rising crime rate.

Key points: New $200 million 24-hour help line, people can report crime or make inquiry

Body-worn cameras will also be rolled out statewide, all highway patrol cars will be fitted with automated numberplate-recognition technology and a new training base will be built for elite police.

The Government is spending more than $200 million establishing the police hotline as an alternative to the triple-0 emergency service.

It will handle an estimated 30 per cent of calls that are not urgent.

Premier Daniel Andrews said people would be able to speak to a police officer to report a crime like a burglary or make an inquiry.

"This is about giving people another option," he said.

"It's all about having access to Victoria Police in a convenient way, but also managing demand to triple-0."

The Government has embarked on a week-long law and order blitz in a bid to tackle a 13 per cent spike in the crime rate, counter perceptions Labor is soft on crime and blunt Opposition attacks.

On Sunday Mr Andrews announced the Government would spend more than $2 billion recruiting 2729 police over four years, including 415 specialist family violence officers.

Modern technology 'as important' as more police

Under the changes to DNA collection, police would no longer have to obtain a warrant to take a sample from a person over the age of 15 who is suspected of committing an indictable offence.

The samples would be destroyed if the suspect was not charged or found not guilty.

Police Chief Commissioner Graham Ashton said the body cameras would save officer's time, capture useful video evidence in family violence cases and improve police accountability.

Mr Ashton said the use of modern technology was equally important as the boost in police numbers.

"This brings Victoria Police to the front of the queue in policing in this country," he said.

Police will get three new helicopters and a plane worth $63 million.

All 220 highway patrol cars will be equipped with automatic numberplate-recognition technology and capable of scanning 2,500 plates per hour.

A new $27 million training base will be built for the elite Special Operations Group, bomb squad and Critical Incident Response Team.

The Government is also banning the use of cash to pay for scrap metal in a bid to stop the trade in stolen cars and industry infiltration by organised crime gangs.
