Starting with Friday night's clash between Geelong and Carlton at Etihad Stadium, the vision from the cameras will be ingested in the same way as other broadcast camera feeds to provide the score review official all angles for any contentious calls.
The small cameras are placed inside new custom-designed goal-post padding so as not to interfere with the ball, and will face each other approximately 2.85m off the ground.
There will be a camera placed in each goal post, meaning four in total at both venues.
Mark Evans, the AFL's football operations manager, said the cameras were expected to clear up a number of inconclusive situations.
"So far this year, we get a conclusive result in about 75 per cent of video referrals from goal umpiring decisions where this is doubt on the field for the umpires," Evans told Channel Seven.
"Of the 14 decisions so far this year where we haven’t been able to determine a result of the referral by using the video and have referred back to the umpire’s original call on the ground, we think that maybe 8-10 of those instances would be aided by these cameras."
The extra cameras are hoped to increase certainty around issues such as whether the ball has passed one side of the post or another, whether it has flicked the post on the way throughl, and if it is touched before or after the goal-line in marking contests.
Evans said plenty of work had gone into their installation.
"The preparation for this trial has taken some work, as we’ve needed to install cabling through concrete to prepare for the camera installation, and we are using the two venues where we play the most matches as the basis for the trial," he said.
"The hardest decisions for us to adjudicate at the moment are whether a ball is touched just before or just over the line, or whether it is touched in the air, or whose foot touched the ball close to the line.
"The cameras should hopefully be able to give us results on many of these."
