gatsos flashing on approach

[s2ooz]

I keep getting flashed by a gatso on the approach to it (ie its covering the oncoming 2 lanes of a dual carriageway)

There were no cars on the opposing lanes - can I still get done?

I thought gatso's dint work for oncoming traffic?

They can't get you when you're approaching, they're not type approved. Relax and enjoy the drive as these 'safety' devices continue to distract you

here are some of the things that can set a gastro off when you drive towards it: HeadLights, if you are following a nother car closely with them on its even easier to set them off and SPEED, nomaly i've found just over 50mph is about right (Driving towards a camera set for 30mph), I understand from what the nice lady from the Plod told me this can vary from camera to camera, oh and before you think i was nicked, i'll tell you i phone the plod station to complian about the endless flashes i was getting...

Give em a bell, there very helpful coz they stoped the camera im talking about flashing....

I once got quite a scare in the early hours of a summers morning travelling at just over 120mph on a deserted (both sides) dual carriageway, when camera on the other side flashed, I've done this several times and the trigger point does seem to be about 120mph on this camera (Brechin N E Scotland). If they can vary the setting in both directions is this just to let them know how many of us are 120mph+ in the other direction, as surely it would be safer to set the thing circa 200mph to avoid any distractions.

I don't think so .... its more likley to be some- thing to do with the fequencey of the flash from the car headlight , i.e following another car closely, as yours is the right frequency probley caused by the crash barrier and its fixings which tend to give a flicker if veiwed from opposite side of road that frequencey when right sets the camera off..... hope that was understandable, minus any spelling mistakes....

K-band radar (as fitted in Gatsos) transmits at (around) 22GHz.

Visible light occupies 405THz (Red) to 790THz (Violet) ... very considerably higher than radar.

It would be very unlikely that a vehicle headlight would put out enough energy at the lower frequency to trigger a detector. Remember that absorption around 22 GHz is significant (which is why the frequency is used for short-range (police) radar).

Surely you want the things going off when you're heading towards them as a public service not asking them to be retuned or whatever? There's only so many shots in them so every one wasted is another motorist saved.

You never know, you might just help someone on 9 points avoid losing the roof from over their children's heads for no good reason.
