No, they are not all visible
Truvelo is generally used to refer to a speed camera manufactured by the South African company Truvelo Manufacturers (Pty) Ltd.
The Truvelo camera is usually a forward facing camera (it can also be rear facing) taking pictures using an flash gun fitted with a magenta filter [1] (the driver is less likely to be dazzled by the flash light). The reflected light provides the film with the correct exposure resulting in a clear picture of the driver committing the offence (considered as incriminating evidence).
Piezo-electric road strips, a known distance apart, are set into the road in front of the camera, and the time between compressions is measured to give the resulting speed of the vehicle. The system takes a single photograph along with four readings on a two axle vehicle and uses the average time for compressions to calculate the resulting speed. The photograph of the vehicle being analysed will be taken when its wheels reach the three narrowly spaced white lines across the carriageway which are present at all Truvelo installations.

Probably not in sunlight or if you were not looking in your mirror.
Inert cameras without a camera fitted flash only once, if a camera has been fitted (gits) then it will flash twice about half a second apart.
They compare the two photos and the number of lines in the road you passed over in half a second confirms the calibration of the radar unit.
I heard if you can brake hard enough to alter your speed by 3 miles an hour between flashes, then the unit will discard the photos.
Better a £60 fine and 3 points than risk losing the front end and destroying those shiney plastics on camera though eh?

Yes if you are going the opposite way to the vehicle being photographed , but in the UK they seem to flash for nothing. In south Africa speed Cameras flash to the front and when you go to pay the fine they will give you the photo that shows the car registration plates and who is driving.
It would be interesting to find out what happens in Europe.

if you do get flashed then when you get the fixed penalty notice ask to see the photo if they cannot provide it you can deny it.there is no case without the evidence.a lot of the time they have not got the photo to produce but rely on you paying up because you know you were speeding.
