Tasmania's police are to be issued with body-worn cameras.
The $3.4 million investment to be announced in next week's budget is designed to gather video evidence while enhancing officers' safety.
Gavin Cashion from the Tasmanian Police Association has welcomed the news.
"Body-worn video cameras will be good for cops, make law-abiding Tasmanians and the community safer, but [be] extremely bad for crooks or those who choose to assault or obstruct officers," he said.
The first devices are due to be in use by the end of the year.
