1. Do they work in the dark?

I assume not.

2. With a fixed Scamera it has to have warning signs and be located at an accident blackspot.

Does this also apply to a Scamera van?

1. They can work in the dark and according to BiB sources on PH have been deployed in the dark.

However, they are far rarer in the dark/rain/fog etc (principly when needed more they don't deploy )

2. These are guidelines! Following the guidelines 15% of sites can be away from accident spots. I believe that vans at these sites don't specifically need signs, but most do.

Can anyone advise the time allowed by the Police to issue a notice if you are caught speeding with a Scamera Van.
I was doing 85ish on a 70mph dual carriageway and noticed a Camera van at the side of the road a little way ahead, slowed to just below 80mph, but I am not sure if I was in range prior to slowing. I have not heard anything to date but am not assuming that I am in the clear. This occured about 3 weeks ago now.

If it happened 3 weeks ago you should be okay as they usually issue within 14 days.

It may not have been a Scamera van it may have been a license / tax /insurance dodger van which will have checked that you had valid car tax etc.

If a van is on a bridge overlooking a road, it can't possibly have signs up, can it?

They are only guidelines.

They get more cash when hidden...

The Somerset scamera vans do operate at night, but I havn't seen one yet.

I've seen many in the daylight though, but have never once seen one displaying a speed camera warning sign ahead of their trap, even though their website claims they always do!

Are you refering to the Wiltshire scam vans sitting on motorway bridges? They may display a warning sign On the B road before the bridge, the fact that you obviously wouldn't be able to see it from the motorway wouldn't bother them in the slightest I'm sure!

Thinking about it, if they're prepared to park on the pavement, forcing pedestrians into the road and arrogantly letting their vehicle cause an obstruction on the brow of a bridge, I cant imagine they care much about the guidelines - if at all!

All in the name of safety! ££

A couple of weeks ago I witnessed a scamera van causing huge tailbacks while parked on a bridge overlooking the A38!

The ironic thing about these vans is that they are only effective (in terms of the speed measuring equipment working) when conditions are perfect for safe fast driving. When conditions are dreadful (and inappropriate speed is dangerous) the vans can't deploy

That's not irony, that's a great way to maximise revenue versus operator time...when conditions are bad, most sensible people slow down, so wouldn't be contributing any "tax"!!!

And the ones who are driving dangerously in poor conditions never get caught

Give the top 20 posters on SP&L a remit to reduce road deaths by a significant amount and they would. Give self funding government gravy train the same remit and road death reduction grinds to a halt!

It'll be easier to sneak up on them and chain their rear axle to the fence then.

They can be placed on the same road where any accidents have occurrred regardless of whether they are speed related or not. Eg 5km down the road from a badly designed junction thats a death trap.


Thats why we hate the ing things

All speed measuring devices work fine in the dark, they provide their own illumination (some invisible to the human eye) when necessary. The only thing that won't work very well is the supporting video evidence (Lidar, SPECS), the same evidence which provides evidence of who the driver was!

Specs is an infra red based system with its own illuminators works day & night fog & rain

Hi Declan.


I'm quite sure the corroborating video frame (for SPECS) is taken from a seperate camera which is based exclusively in the visible band.


Can IR (905) really pass through fog?

To a degree, yes. Certainly better than visible-spectrum light, as it's got a longer wavelength. But not a pea-souper.

Specs cameras are PIPs Technology units, the lens units are standard lenses that see both IR & normal light so yes it will look like a normal image in daylight, with a slight strange hue with the IR reflection off greenery.

I disagree. Two seperate cameras are used, the monochrome plate reader working exclusively in the IR band (spectral response) to eliminate effects from uncontrolled light sources, the other 'Colour Scene Overview' Camera working in the visible band as normal.

Here is what I reckon to be a good example of a set of ANPR images from a mobile unit; no daylight in one (can't see anything except retro reflective surfaces), no IR in the other:
