How exactly do mobile speed cameras work ??

I have don't a lot of research and have spoken to a number of my friends, but I always get different answers. I just want a straight answer
Well anyway I was going around 80km in a 70 zone on silverwater road, NSW
I was travelling towards bankstown, and on the other side of the road facing opposite of me was the ford territory, I quickly slowed down to under 70, as I passed the front of it.
Do mobile speed cameras work like regular cameras and get you as you pass them ? Or can they catch people from both directions, and even if you're on the opposite side of the road (I was facing the back of the ford territory) and drove past it at 70

Any advice will be great, thanks heaps!!

Not sure how it is in NSW, but in QLD we have vans that can catch you from both directions. However, they mostly only use the vans that can catch you from one direction in surburban areas.

The Ford territory does both directions. They have 2x IR cameras mounted on each direction.

It likely snapped you before you even slowed down.

How about motorcyclists ? If mobile speed cameras catch you from front on, they don't have number plates on the front ?

Yep for motorcyclist its a free pass if you manage to pull up quick enough, RTA has been trying for years to get front mounted number plates !

Those ford territory in NSW can catch you on a flat road, 2km in either direction, so you would have been caught even before you noticed it IMO

and motorcycles with front number plates will never happen, its kind of ironic how the RTA etc wants to impose road safety but wants to implement a front number plate on a motorbike.

What is the safety issue of having front number plates??

Some bikes have a do not have mounting point on the front as the forks are there.
If is on the fender mounted sideways the camera may not pick it up.

CBR, no mounting spots

Sure the government could make a law saying that all bikes must have front mounting points on the bikes.

I've seen them from a distance here in Sydney, slowed down as soon as I saw it and never received any fines.

Sometimes sit hidden after a bend though, sneaky ball lickers.

in case of an accident the front number plate may go into the driver

Or at the bottom of a hill

How do they work? They ping you with a laser and get a measurement from that. How close, probably 50 metres, more info here - http://www.rta.nsw.gov.au/roadsafety...lespeedcameras

"Previously there was one warning sign 50 metres before a mobile speed camera vehicle. There will now be 2 warning sign on the approach to a mobile speed camera. The additional warning sign will be placed up to 250 metres before a mobile speed camera vehicle."

In NSW they are just a few meters from the car itself.

In Victoria, hwys is one direction whatever the speed camera is facing, they'll catch the cars going the same direction. Opposite direction is lucky.

In suburban streets of 1-2 lanes flowing both directions is unlikely, i got caught doing the opposite direction 6km/hr above the speed limit thinking they don't flash opposite direction vechicles.

Usually an odd park mobile speed vehicle, is the obvious sign. I've seen them park on grass, i think footpath, behind really big trees, when i was heading down to philip island there was knee high crops and they were parking in it. Parking in front of cars is a common one especially on pascoe vale road where i memorised alot of the cars then one there was a odd commodore which i've never seen before, past it at 55km/hr and bam it was a speed camera. If you use suburban roads alot, it pays to memorise alot of the park cars.

The way they are park once you pass them, drive at normal speed for 100m is good rule.

Laser.

Distance from car and time for laser to be fired and bounce back even though the time is nanoseconds it can be measured.
