Redflex pole mounted is using something in conjunction with 'K' band to detect speeding. The alerts you get are only coming from bounces once the system is activated, very smart, I/O I think and how they do it is coming with a bit more investigation. Look at the road surface before the camera and they use another detection before the I/O road sensor which I am looking into.

Potentially electromagnetic sensors in the road before the camera?

It will be interesting what you find given nothing was explicitly stated in the recent official information act request for information regarding what is used in NZ for speed enforcement..

Are you sure? I thought the dual radar system detected vehicles with the high K band antenna, then activated the lower freq speed tracking antenna.

Some have sensors in the road. Been doing work on my Reflex detector and noticed odd behaviour of the unit. I live in a rural area and it's difficult for me to go to town and catch the right traffic flows. I will figure it out eventually.

Are they like the original analogue cams, two strips across the road?

Yup this, I think the Higher frequency is out of range for normal radar detectors. Unless your home-made one can go that high (Doppler radar quoted as K band 23.924 - 24.325).

Yes it does work in that band. Interesting choice of camera as no major manufacturer wou;d be bothered making an RD sensitive to Redflex when in other countries there are so many other systems to consider. So the retail RD's are a compromise. I do have a solution that the Chinese manufactures could implement for the whole world to combat all types of radar and lidar but won't happen as it's very rare to find somebody thinking outside the box. Bankroll me and I can make it happen :)

Who knows what the Chinese want to prototype something. My idea is to use their existing RF boards, slight change in feed horn and completely new case.
I need to track down the manufacturer (OEM) not the suppliers. You might help by tracking down the board manufacturer of those cheap V7's, 'ANW' for me.

Are you able to upload a video of your Proof of Concept detecting redflex radar?

crowd funding could be one option... also volunteers on this forum could help....keen to see a product that could detect Redflex for sure!

No, I will not post anything here.

Thanks for the link, it looks like them, I will give them a try.

I'll be down in Dunedin in a few weeks, would be good to see it in action if you're free.

No! Last time I developed something that was very smart a tech that worked for the Government just smiled and 12 months latter they were selling it to industry. Going to run it by a friend who has the same background as me and because he's a drinking man and chases women I trust him. He knows what I am up to but only has pieces of the jigsaw that he helped me with.
Sorry, just very nervous. I even worry about the Chinese stealing the concept because it will work.

I feel like you are being overly protective over this.
No one is asking you to post a skematic or even show what it looks like.

Just a video demonstrating what you have already said what you have been able to achieve.

For example a video of you driving towards a redflex speed camera and it alerting at the distances you have quoted on here. You don't even need to necessaryly show us what the thing looks like... Let alone how it works.

I don't see how this could lead to your interlectual property being stolen from.

It's not about Redflex, it's about how to single out detectors that work in each country. Do you want me to drive to a Redflex and make something go beep beep, it could be just a con and quite frankly your missing the point, Redflex is easy but not with commercial detectors, what is the issue here is how do you single out the LE that suits your country without it being expensive. That's what I am protective of!

A lot less than before but I need to narrow the width a bit more. Can't get away from very strong signals though. To get real tech then can filter out by signature but don't know if they have the same everywhere. That would drop the falsing to almost zero but any microwave tech can design that, it's the way the detection is implemented.
Going by what I have found out the RF design may be from a Russian.

Would be far better if I could get somebody like Uniden interested.

Keep it in NZ, team up with @Mithheru He has done a great job with the Databases, I am sure both of you hardware + software could come up with something great.
