Mobile cameras

[steve320ise]

Are the mobile cameras in vans set for a direction or do they do both at the same time, cheers

[HoHoHo]

My understanding is they face in one direction at any one time.

I was driving home on the M23 this evening at around 6:15pm (dusk) travelling in the outside lane with others and almost certainly in excess of the speed limit and a van was parked half a mile or so before the services by Gatwick and I'm now wondering if I'm about to receive a letter in the post! I slowed down but I'm not sure quickly enough.

The speedmeter (camera) will be operating out of one opening in the van (usually the rear door/window), and they can, and do, measure the speed of vehicles travelling towards and away from them.

Didn't know that, thanks.

Is that all the time or they have ability to operate in this fashion?

All the time. You've been caught.

I was OK having gone past but if it managed to focus on me coming towards then I'm looking at a fine and points I suspect.

I guess a two week wait starts (sorry to hi-jack the thread)

I was in the back of one recently. The operator can do either direction.

[steve320ise]

So its the operator who sets the direction then

The operator doesn't have to 'set' the direction - the speedmeters they use automatically determine whether a vehicle is approaching or receding.

Mobile "cameras" are actually speed meters - what you might call a speed gun. The device is often linked to a video recording machine. The "photographs" are actually stills from the video. Speed meters can detect the speed of vehicles incoming and outgoing. If the device is attached to a tripod then I suspect it might take a few moments to reposition. If not, then there wouldn't be a problem moving it around.

Not a bad attempt. Try this:

If not, then there wouldn't be a they are usually on fully floating/fluid heads so there is absolutely no problem moving it around to aim at and track vehicles.

Add it to your portfolio; no charge.

I was thinking about getting the speed meter from one end of the van to the other, or one side to another - depends how the van is parked and the topography. I've been in a revenue van - in a court car park when a demonstration was given to the court by the operator - so I'm familiar with the operation, thanks.

Careful agt, this poster also posts as emmaT, but I think it's our old friend Callaghan with his deluded, blinkered, retarded mentality. Looks like he's had a sex change mind you, or maybe it's his wife deputising. Either way best ignore him; i.e. don't feed the troll.

Thanks for the heads up. Although, in fairness to pitmansboots (dairymilk, emmaT?) - whatever you might think of him personally and his opinions, he does generally know what he's talking about when it comes to the mechanics of speed enforcement.

It's the same with the hand held laser speed guns. The officer just points and shoots, it doesn't matter whether the vehicle is coming towards or going away, you're caught!

I was with a traffic officer (at a speed trap in a 30 mph zone) and he pointed the hand held laser at the rear of a car that had just gone past us and which was driving away from where we were, the laser device indicated 38 mph [I had asked him the exact same question... can the device indicate the speed of a vehicle moving away from the device?]. Less than ten minutes later the same car returned, now coming towards us. The hand held laser device was aimed and, yes you've guessed it, it read 37 mph. The driver was stopped and said... "Oh! no, you haven't stopped me for speeding have you? I've already got 6 speeding points on my licence, if you do me I'll have 9!". The officer said... "well, ten minutes ago I recorded you going down the hill away from me at 38 mph and now I've just recorded you coming back up the hill at 37 mph, so that's 3 points from ten minutes ago and another 3 points from just now so, with the 6 points you've got already that makes 12 points in total, so you're looking at a ban!" "Oh! no!" said the incorrigible speeder, "but I have to take my daughter to school and back each day, Oh No! Oh No!"... "OK, I tell you what", said the officer, "I'm in a good mood this morning so I won't report you for the first offence, but here's a ticket for the second". He then proceeded to give the driver a stern lecture about keeping to the speed limit etc. etc.

What's really amazing about this story is that the driver must have known that we were there; she had driven past us not ten minutes earlier; she knew that there was currently a speed trap on this road (we were standing on the pavement with Hi-viz jackets on for all to see)... and yet, despite knowing all of that and knowing she had 6 points on her licence, she still drove towards us at more than 30 mph on the return journey!

And that level of observation & planning is why a lot of limits are stupidly low boys & girls.

hmmm he seems oblivious to the serious technical flaws in LIDAR (slip/multiple reflections/non-alignment between evidential 'pictures' and the actual object being targeted etc). These things should not be allowed to be used to prosecute members of the public.
