That's not true. Those cameras are only used for the world cup.
In the Premier league they rely on the broadcast cameras.
You are right I was misled ! That definitely blurs the lines. According to Givemesport : VAR uses cameras than run at 50 frames per second, with one picture taken every 0.02 seconds. According to FIFA, the
VAR system had a success rate of 99.3 percent, up from the 95 percent of correct calls by referees without
VAR.
However there is light at the end of the tunnel (statement from yesterday (for me +8 GMT) :
football law-makers IFAB (International Football Association Board) have stated that VAR should NOT be used for marginal offside decisions.
Lukas Brud said the IFAB will issue guidance on how to implement the technology with regards to offside, which will essentially mean telling the English authorities that it cannot measure such marginal offsides - as they are not clear and obvious.
"Clear and obvious still remains - it's an important principle. There should not be a lot of time spent to find something marginal," Brud said. "If something is not clear on the first sight, then it's not obvious and it shouldn't be considered. Looking at one camera angle is one thing but looking at 15, trying to find something that was potentially not even there, this was not the idea of the VAR principle. It should be clear and obvious."
Your statement had me scurrying to investigate though. It's seems that the quality of those broadcast cameras can vary .. it may not always be the mobile versions we see Sky, for example, using but fixed cameras installed at the ground, or it could be soon if they aren't in use yet - I can't find a definitive answer to that..
Only introduced towards the end of last season, Intel’s True View camera technology could provide another angle – or multi-angles – for BT Sport and Sky punditry.
The Emirates, Anfield and the Etihad Stadium are the three stadia to have installed the 38 x 5K cameras that ring the pitch (in a deal with Intel) and allow for footage to be viewed from any angle – including from a player’s perspective.
The system uses the UHD cameras to capture volumetric data which Intel servers then process to generate three-dimensional replays from every angle.

This is interesting and seems it's the way forward planned by the PL :
So unpopular has the system become amongst supporters, frustrated by the lack of communication inside stadiums and the time taken to make decisions, that anti-VAR chants are now a regular feature during games.
One of the major frustrations for fans has been the time VAR requires to check offside decisions, a result of the often lengthy process involving the video official manually generating a new offside line across the pitch for each incident. However, the Premier League plans to adopt new
‘limb-tracking technology’ to increase the accuracy and speed of offside decisions.
Developed by goal-line technology creator Hawk-Eye, the new system will
use multiple cameras in order to create an ‘automated offside line’, freeing up video referees from the time-consuming task of manually constructing the line.
“The technology will track the back foot of every outfield player in each VAR game, providing a constant offside line for video referees to assess instantly, whenever a decision is deemed too close to be ruled on solely by the on-field officials,” reports the
Daily Mail.
The ‘limb-tracking technology’ will only be used for checking offside decisions, leaving the Premier League still with a number of other concerns to address.

At this point it’s worth considering a few points you might not know about VAR. Those thick lines laid across the screen to illustrate Sterling’s offside are largely for our benefit; the VAR official uses a much more precise line just one pixel in width. The pass is measured not from the moment it leaves David Silva’s foot but from the first point of contact between the ball and his boot.
....there are several high-speed variables at play which VAR is being asked to calibrate precisely with 50-frame-per-second cameras. VAR isn’t automated; it’s a man in a room with a Hawk-Eye technician by his side trying to marry up several moving parts on a screen very quickly. He is asking for blurry frames to be stopped and minuscule lines to be moved and dots to be joined with armpits, and only once he’s made those choices does he get an answer.
If goal-line technology is comparably definitive to tennis’s Hawk-Eye – the ball is in or out, goal or no goal – then tight offsides are more like cricket’s ball-tracking, where we think we have the answer but we can’t be sure. In the United States’ MLS, VAR is used only for clear and obvious errors and that extends to offsides – if the video official isn’t certain after a quick check of the replay, the game goes on, much like cricket’s method of sticking with the umpire’s call on marginal LBWs. The Premier League has instead followed the Bundesliga model of black or white, despite a thin line of grey ...
The Premier League is open to change with all this. It has worked tirelessly behind the scenes to create a version of VAR tailored to protecting its product of fast football and it will evolve accordingly over the coming seasons. It has already learned one lesson from the Bundesliga, which came under criticism over long breaks in play as referees checked their pitch-side monitors: referees in the English top-flight have instead been encouraged to trust the advice of the VAR most of the time.
And if I'm reading this right then VAR allows for a 13cm margin of error ? So where is this seen ? In the thickness of the lines we see on TV - even though those aren't the lines used to assess ? https://www.givemesport.com/1498162...an-not-every-offside-decision-will-be-correct
But going back to that IFAB statement Givemesport said :
The IFAB have stated that this information is not new, so why have the Premier League chosen to ignore it and sour a number of games throughout the season?
Mike Riley and PGMOL (Professional Game Match Officials Limited) surely need to have a long hard look at themselves for helping fuel such dismay for the new technology. It's only been the marginal offsides that have stirred up such rage from fans and if they weren't even necessary, then it's a pretty spectacular fail by the English officiating authorities.
