See chapter 8.7 - but which is really probably more for prior to an infringement getting to SPER / your later SPER notices, & prior to court (which may best best avoided). Used to be for process to request review of infringement / that you believe error may have been made - u write to a senior officer like district superintendent (not sure now).
Maybe phone transport dept & ask for advice & Google their website - check back of fine & initial SPER paper too for any instruction on how you might request review etc. Don't know if u can request the full photo, or how I go if car next to you/nearby/behind - they may already try to account for this,
Speed camera calibration
Well technically a lot of scientific testing equipment may need calibrating regularly & some even each use. It depends on the equipment type.
Think maybe a few years back it may have been that traffic speed cameras (eg hand helds, mobile ones) has to be calibrated/re calibrated a lot eg maybe even each use/day.
But I vaguely recall a special law being introduced somewhere to say that Police no longer have to do this anywhere near as much. My vague recollection is that this may not just be state specific, but that it might have been a federal law that was introduced - not sure - you would need to check state/federal law regarding police calibrating.
Part of the law change may have been more to help reduce drivers challenging tickets
Yeah, I'm Qld the last few years police keep saying they dropping the % margin they allow over the speed limit but won't say what that percentage so its a guess.
Then it's claimed most car manufacturers set car speedo so it overstates speed u are actually driving by a few kilometres - so it's claimed in media/on net - who knows if it's real or not or for which car brands ?

- speed camera calibration in QLD - eg see chapter 6 of the Jan 2017 QLD police manual for traffic matters - also chapter 9 mentions cameras
- the section on calibration in chapter 6 does mention a "National Measurement Act" too, & about manufacturers specifications, & about 12 monthly calibrations or something, but maybe this vary with camera (or not)
- they don't seem to have to calibrate their cameras as much as they used to
