Mardi Gras revellers and police officers will train cameras on one another on Saturday night in a bid to avoid a repeat of last year's brutality allegations.
"It's going to be a bit of a recording fest," Surry Hills Police commander Tony Crandell told AAP.
The arrest of teenager Jamie Jackson Reed was at the centre of claims of police heavy-handedness at the 2013 parade.
Hundreds of angry protesters marched on Surry Hills Police Centre after footage emerged that showed a police officer throwing Mr Jackson Reed to the ground.
Superintendent Crandell, the NSW Police LGBTI spokesman, said officers with video cameras would be deployed for the parade and Sydney council had installed temporary CCTV cameras.
"Some of the difficulties with last year was that there was a lot of complaints made in relation to the exercise of police powers, and sometimes it's difficult to investigate matters where there's a lack of evidence," he said.
Police won't be the only ones wielding cameras.
A team of volunteers armed with legal training and video equipment will be recording interactions between officers and partygoers.
"There was a number of incidents that we were really shocked by and we had volunteers outside the party who were shocked by some of the heavy-handedness of police activities," Inner City Legal Centre director Daniel Stubbs said.
"If there is a problem, then (the video footage) becomes evidence."
This year's parade is tipped to be bigger than in 2013 with a record 140 floats poised to make the journey down Oxford and Flinders streets.
Among the parade's eccentric features will be a nine-metre, Strictly Mardi Gras trailer complete with a 98-member cast.
One of the minds behind the float, Strictly Ballroom director, Baz Luhrmann will attend the parade as will performers Delta Goodrem and Tina Arena.
Supt Crandell assured chaps-clad parade-goers, who were told to cover up last year, that police would show more discretion with their decency inspections.
"We don't want a situation where chaps have been worn for 35 years and on the 36th year, we say no," he said.
"I think they will be making a massive comeback."
