The Police union is celebrating the decision to work towards rolling out body cameras - but wants it done right. 

Police Commissioner Richard Chambers says staff are assessing options for equipping frontline officers with the technology. 

The Police Association says it could clear-up misconceptions in the field, reduce complaints, and lead to more guilty pleas. 

President Chris Cahill says body-cameras have become the international standard. 

He says many officers in Australia don't want to deploy without the technology.
