I have had a radar detector some 12 months and use it on trips in the car and on the bike. The detector has never given an alert on a fixed camera. It works with the camera vans parked on the side and the HP.

I am wondering how often the fixed units are operational? My radar detector seems to be programmed corrrectly and I believe both the van based camera units and fixed cameras are on KA band.

There are three units I pass on a regular basis: Ngaranga Gorge, Petone SH, Upper Hutt SH. These units have never triggered the detector.

Yet Ngaranga and Petone defiantely have cameras lots of the time ...

If they are digital they probably work on piezo electronic detectors embedded into the road surface whereas the van cameras, being mobile, use a laser or something......

Fixed cameras use no radar, but sensors under the road surface similar to traffic lights.

Look at the road surface next time you ride past a fixed camera box.

You will need a radar with GPS alerts for them.

Fixed camers work on sensors in the road!!!!!!!

My detector is a Uniden GPS type and lets me know where every fixed/redlight camera is (whether operational or not). It also warns me of any suspect spot where plod might regularly be found, and also will warn of random vans and HP (mostly) I can update it at anytime on the internet. Would be cool though to know when those fixed cameras are actually active for sure.

Yep. Fixed cameras have two strips across the road with a loop between them. The two strips are to measure your speed and the loop is to ensure there is a vehicle present. Mobile cameras use radar.

Yup and they are quite distinctively hexagonal in shape. Look for tarsnakes just past the camera position that look like this ...

You'll often see more than one, they can be in as many lanes as there are lanes on the road going in *both* directions. The picture you get will have "Lane 2" along with the date/time stamp. (I read about it ... ok?)

Up to four lanes. A,B,C,D :)

Why is it that some traffic lights don't detect bikes, yet the speed cameras do?
Luckily they got that one sorted for us.

Thanks for all the info. My assumption was so wrong. Now I must be more careful; especially when the number plate end is facing the camera.

It's an EM sensitivity setting that can be adjusted. Contact the local council and they can sort it. If it won't trip for you try putting your side stand down on one of the lines and give the engine a bit of a rev - makes a bit more EM noise and usually triggers even the most recalcitrant sensor.

Yeah, four lanes. IE Pak highway camera doesnt get the opposite left lane, and I've always ripped past there, cage or bike.

I've found that the fixed cameras never get triggered by my bike. Too small perhaps? (The bike that is!)

I get worried when people speed past fixed cameras in the middle of the day, and say "Oh but I didn't see it flash!"

They dont flash in the middle of the damn day - the sun is out!

I guess they'll find out when they get their photo in the mail:devil2:

If it wouldn't be possibly the most stupid thing I'd have ever done (and there's a fair amount of competition for that award), it'd be fun to write to the bastards in blue and ask for the photo of me (facing forwards) going past a camera with my front wheel a good 50cm or so off the deck. I know the date and I know the location. Reckon I could claim it for research purposes?

For legal purposes, the above paragraph does not form a confession, but is simply me bullshitting. Honest, m'lud.
