Mr Trafford said while parking officers were trained in how to defuse aggressive behaviour, sometimes it was not enough.
"Our staff do unfortunately deal with difficult situations including verbal abuse, physical abuse, aggressive behaviour and threats," he said.
"These cameras will help hold those responsible to account and provide clear evidence in the case of disputes.
"Other councils with similar devices have found that when cameras are worn, fewer conflicts escalate and conflict situations are less likely to turn aggressive, which gives confidence to staff and the public."
Mr Trafford said the council had strict guidelines for the use of body cameras.
"The cameras on parking officers will not be used for surveillance but for when the officer finds themselves in a threatening situation and feel unsafe. Parking officers will also wear ID tags advising they are wearing a body camera."
Parking officers will trial two types of cameras over the six weeks.
The collection, storage and use of any personal information captured by the cameras will be managed in the same way as other information is managed in accordance with the Privacy Act.
