Has anyone checked to see if number plates like this are still legal?

It's called a Slicer, and for that reason it's illegal.

Guess I'll have to go the ironing board route then.

BEWARE: The cameras are very high-tech and high-resolution. They can read the details of your license disc in your windscreen. So if your numberplate were to "fall off" and you didn't notice, they would be able to get your details off your license disc and still bill you.

This was quoted elsewhere and the consensus there was its not true.

Personally I doubt of they read your license disc - just too haphazard to rely on - people put them all over the place and with reflections etc -its just too much of a hassle to deal with.

We need to verify this stuff before circulating it and starting rumours IMO.  

I do know that their system works on two hi res video cameras that determine the vehicles dimensions.  The use OCR to read your number plate if you dont have an etag. Remember they only have less than a second to do all this as the car flashes past, they cant afford to allow the system to go into backlog, so even with high speed computers the real time processing will be kept to a minimum.

I estimated the downward view of the cameras as 30 degrees from own examination if photo's of the gantries.

I would imagine the angle of view of the cameras is fairly narrow, ie it looks at the lane beneath it, maybe a bit either side.







I hear you Alan, but I got the info from a mate who I regard as a reliable "inside source". So should my number plate just happen to "fall off" I will also make sure that my license disc has a bit of mud, dirt, squished bug or whatever in a strategic place.  ;)

Would be such a shame if they managed to get my details from a license disc...  just making sure ALL bases are covered.  :thumleft:

IWould it then be possible for cars travelling slowly to be so close as to obscure their plates under the gantry? How close would you have to tailgate to obscure your plate?

Presume this would be way too close.  Take two cars. The height difference from the number plate on the one in front to the bonnet edge of the one behind is very little in most cases. You will probably have to get as close as 300mm to obscure a plate.  Riding in front of a truck might hide your plate but then you also need a truck in front of you to hide the front plate as the cameras look in both directions.

Also call bullshit on the licence disc story.

My deduction.
Your licence disc is about 80mm?  To read the information on it you need a good resolution/pixels of about 800x800?
If the camera only covers 4mx4m of the lanes then the image that they store have to be 40,000 x 40,000 pixels to be able to read the licence disc.
What mb size would that image be? How much storage space would you require to store millions of those images?
Even if they just store a part of the image I doubt if the cameras would run video at such a resolution.

If these cameras are as good as claimed why do we need even have e-tags? ::)

Does this mean they don't have the resolution to see me flashing my willy at them from inside my cage?  :peepwall:  :ricky:

It is strange that the Gautrain's fibre optics are sabotaged regulalry (e.g. by the taxi organisations) - but on this front, there is no 'knowledge' of now the systems are connected. Is it all wireless?

I am sure that info will surface over time.

That is a good point, and it probably comes down to the neccessity to register and have automatic payments otherwise the system will become too cumbersome as OUTA has pointed out all along.

I mean, from what angles must it be visible? Can it be tilted "slightly" backwards?

Why I ask is because I am involved with vehicle access control on our campus and no known camera can read the disk at present reliably enough to collect data from it while in motion, the vehicle has to stop and be manually scanned. :deal:
We are installing our own "e-toll" system because of that. :biggrin:

I shudder to think of what those cameras cost that read the number plates on the gantries, we have had to compromise cost vs resolution. On our fast entry lane we will not have cameras on the number plate, only on the faces of drivers.

b)   in an upright position or within 30 degrees of such position;
c)   in such a manner that each letter and figure thereon is clearly legible;
d)   in such a manner that the whole number plate is clearly visible;
e)   to the back of a motor cycle, motor tricycle, motor quadrucycle or trailer; and
f)   one to the back and one to the front of all other motor vehicles :
Provided that no person shall operate on a public road a motor vehicle first registered on or after 1 July 2011, unless the number plate fixed to such motor vehicle is affixed within 20 millimetres from the edges by means of 4 millimetres rivets or 4 millimetres one-way self tapping screws either directly onto the motor vehicle or onto an integral part thereof or onto an intermediate metal holding bracket which complies with the provisions of SANS 973 "Number Plate Carrier" approved by the Department of Transport, and which is attached to the motor vehicle in such a way that it cannot be removed while the number plate is affixed to it in the aforesaid manner.

I suppose so.

But to be completely unreadable (side on) to a camera you would need to tilt it by about 60 from degrees from vertical, but every little bit helps.
