Can a clever person answer this for me....?

Some Gatso cameras can tell the difference between a car and HGV, so if the limit is 60 mph for cars and for HGV's it is 40 mph, if HGV's pass the threshold of approx 45-50mph the camera would be triggered.
These cameras are widely used now in the UK so the answer to your question could be yes if it's this type of camera on the road you are talking about.
(Look up Gatso Camera it will explain)

yes , there is no way a speed camera can identify vehicle type , but when we ALL have electronic trackers fitted we will all be in the same boat !

There are several camera sites already set up, with the ability to catch speeding H.G.V.'s. The A303 north of Salisbury has two and there is one one the A446 north of Birmingham, for example.

There will be many more introduced in order to help to Government to raise revenue...

I happen to be a speed camera tech. It can only be set for the posted speed limit, and can't discern the difference between a regular vehicle, and an HGV. For the drivers of the HGV's it's a matter of trust, and if they exceed their 40 mph limit, they'd probably cause an accident anyway, which means it goes on their record.

simple

the camera is set to 60mph

it cant tell what is going past,so it blitzes everything over 60

No because the camera is only tripped when you break the 60mph limit on that road. It is not intelligent so it cannot tell the difference between Trucks,cars,vans,buses or anything else that passes through the beam.

The camera doesn't know the difference between a car or a lorry - it detects only the speed. If the speed is over 60mph which is the national speed limit for this road, it will register as a speeding vehicle.

HG V's are allowed to do 60. Speed camera's only measure speed not the type of vehicle. I have know them to flash bikes and even a large bird - although they would have trouble getting the fine off that one. There was a case of a speed camera flashing large white vans who were within the speed limit but it read that they were doing in excess of 80 mph!
Some camera's aren't accurate either. It was found that one had flashed drivers doing 32 in a 30 and though they were just over the limit - which is easy enough to do - they were reading a speed of 45 mph.
I think they have to be regularly serviced, so it anyone out there gets caught, check when the camera was serviced as this may be a handy loophole in the (stealth) law.

All the camera knows is that it has to snap vehicles exceeding 60 - it's essentially a pretty simple-minded bit of kit.

It would be very unusual for there to be two speed limits on one srtetch of road.The limit would probably be 60mph. for all vehicles which would include HGV's. I personally have never seen road signs giving a different speed limit to lorries.Many years ago, at least 30. all commercial vehicles had a speed limit of 40mph except on the few motorways then operating.There were no cameras then so the limits were controlled by the police cars.The 40 limit even affected light vans as it was for all commercial vehicles irrespective of size.This law was eventually repealed as more motorways were built.

I'm going to say maybe because you are allow only 40 mph (Because of driving HGV's) and cameras was set at 40 therefore anything over 40 will set the camera off.
Camera went off nailed you because you were speeding for your required limit!!
Just a thinking guess?

I am a very clever person but coming from a South Asian Village. Have to travel 96Km to see a train. I do not know the colour of UK. Sorry.

HGVs are required to run 10mph less then the national speed limit when it is applied. So, unless you've seen a sign that says they can only go 40mph, they can go 50mph.

The cameras are set to a speed, they can't tell the different types of vehicle, so they are set to the national or local speed limit. Simple as that.
