Know your enemy

[Groenie]

As some clever dude said some time ago....

So what are the technical specs of these gantries, cameras, RFID stuff, etc?

I'm sure there had to be a tender doc, specifying all tech requirements. And then some information on what exactly was implemented.

Stuff like signal strength, angles of the cameras, field of view for each......

I think the more we know about this, the better we can fight it.

Interesting thread to watch. Electronic counter measures...

[Bensien]

Does it take the photo from the front or the rear? Is there a visible flash? Does it always flash or just in poor light?

[DRAZIL]

there is a weak point and that is ,the cameras have to be cleaned.
All one needs is a cloned Sanrail maintenance vehicle then find a maintenance worksheet or forge one and go do some midnight maintenance with hydrochloric acid, phosphorus, hammer and chisel...........

Ive just come back from Sweden where they have also installed these gantries without the support of the masses. The normally passive swedes have taken to shooting the cameras with paintball's.

I laughed when my colleauge told me the story and remarked on us having access to live ammo

The camera's ARE high-tech. They take a pic of you from the front and from the rear. They use 3g imaging software that calculates the length of your vehicle, and automatically apprtions your toll fee.

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.

And now I am REALLY going to set the cat among the pigeons....

There are traffic cops sitting in the Sanral control room. They are informed about vehicles without number plates, and then said vehicle is tracked using the freeway CCTV system, and the cops on the highway are told to pull you off and nail you.

Yesterday I used the N1 from Stormvoel to Rivonia, and back, and I saw large groups of Tshwane Metro cops on bikes at the major intersections. I saw guys that had been pulled over without plates.

Beware. KNOW your enemy.

always wear gloves - they have your fingerprints from your license
disposable vehicle or stolenborrowed sanrail vehicle
beware CCTV cameras - wear safety goggles,respirators
be fit - in case you have to run

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've been through 4 gantries with the bike and checking on the site it says I've only been through 3. I passed one between 2 big 4x4s. Don't know if that has something to do with it?

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?

Downward angle of 30 degrees means the triangle base is twice its height.

So measure the distance from your eyes to the floor, and stand double that distance away from you number plate and look at it.

That's the same view the camera has.

I am working on a few ideas. I suppose it would not be wise to discuss them here

[DeepBass9]

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

[DRAZIL]

these cameras operate on a 220 Volt system. All one has to do is find the distribution board that supplies the cameras and remove the neutral and replace it with another phase thus giving the cameras 380 volts which should fry something.

The municipality screws up like this often when working in suburbs.

Which means that a numberplate mounted further back under the tail piece would not be picked up ?

+1  There are emergency lanes under some gantries and these also have their own camera.

So if you are transporting an ironing board on your luggage rack, you are sorted!

Sanrail spys are everywhere and traitors who will sell out these ideas

Sorry should've been a bit more clear. Passed under one while lane splitting between 2 big 4x4s

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