Speed Camera - Oh Shit!

lol.. good idea.. buts thats what the flash is for ! (about 1/10,000 of a sec duration). You would still be in focus in a Mig29 at Mach 2.

Look at some pf the photos from Wanganui, Sherriffs was going as fast as you can on a street and there are some fantastic shots of him in perfect clarity!

Most cameras use a "moving shutter - curtain approach". That means different parts of the film are exposed at different times. So, even with a fast "flash", the shutter of the camera will be open for much longer. Its called the flash synch speed. In virtually all modern cameras it is 1/60th to 1/120th of a second, making the LCD idea very effective.

was going out this morning and had to go over the bridge, the white van was there just past all the road works (heading south over the bridge) i was doing about 95 at the time but no number plate at the front so should be fine, this was about 9.30 this morning.

Only reason why they sit there is because they know people dont do 80 till they hit the bridge.
So easy money for them

Probably got snapped in the cage by that one this morning, unfortunately. Was doing 100ish, but plenty of other cars in the frame.

There are people that slow down for the bridge? Interesting...

I still havent't had my bike speed camera fine but I think I may have accidentally been snapped from the front on Onewa Rd. a week ago

Has anyone actually tried the LED on PLATE idea or is it still just an idea and not tested ?

There is a white or red van on the lead out to the bridge northbound just after the 80Km/h sign when coming up from the second to last on-ramp to the bridge. its there every 2-nd weekend. been doing that root dayly for 2 years now, its there with + - 1 week difference sometimes.

Yes, before Christmas there were a couple of bikes with radar guns in the same spot. Was doing 75-80kph (the limit) in the middle lane, pulled out into the rightmost lane (speed limit changes to 100kph further up the road) and grabbed some throttle to keep up with lane speed, 90-95kph. Saw the bike cops and shat myself, watched them in my mirror as they leaned in to talk to each other and watch my bike ride off. Never got a ticket in the mail. Probably were surprised to see a CB250RS go that quick (or maybe they were admiring the new fork gaiters). Might've been the two bike cops who were racing down the same motorway (wasn't it?) at high speed

They would've been sending off a fair few tickets that day. It used to be 100kph there but with the road works it's down to 80kph -- why I don't know, they're all protected behind massive concrete barriers, and it's not like they're running across four/five lanes of motorway traffic, there's overbridges for that. It has effects on bridge congestion too, by not opening up the limit earlier. Might be some OSH thing.

Use the LCD panels to cover about 1/2 of your number plate each.

Use a simple oscillator to turn one LCD dark at a time. ie one half of your plate is always blacked out.

If you switch at (say) 30 hz, the human eye will see your plate normally, due to persistance of vision.

However, your number plate cannot be photographed unless the camera has an open shutter time of twice your on/off cycle time.

And at 30hz, thats 1/15 of a second, by which time your bike has moved around 1m at the 50kph speed limit. ie blurred unreadable photo.

Its an easy way of turning speed cameras off, no need to burn 'em with an old tyre.

Easy, cheap, effective, might even be legal !

yes u put this on your plate . but which way faceing out or in

What an unbelievable clever idea.....I don't know if it realy works, but it would be worth a try just to find out.....

Location was on the approach to the harbour bridge, 8.00 am on a Sunday morning. I actually remember that day with some clarity, there was very little traffic...

Started riding on the road in 198? something? 1 ticket in 20 odd years is pretty good.

I'm going to write in and get the photo - it'll look lovely in a frame on the wall, just hope I wasn't scratching my arse or something...

i'm sorry can you see whose driving?

could be anybody...hes got a helmet on.....

it aint me....

honest.

and thus u save urself 230 bucks

**danchop** · 6th January 2008, 07:43

i still dont get how you got snapped on a bike cause the camera would have to be on the other side and cant fiquire it getting a good view of plates over the barriers?the 80kmh limit is permanent and goes right through until the newmarket overbridge
