Ultimately there is a reason GPS was added. In my opinion against redflex you need both the best K band you can get, as well as the best GPS you can get.
And, thanks to your work we have a pretty damn good database. The Kaimai Redflex location was precise.

Done some testing, Horizontal vs Vertical against a redflex pole cam, facing away from me.


Another test stationary with cam facing towards me I was get 1 bar horizontal and 4 vertical at

Drive by was same with vertical showing a great improvement,
Vertical 250-300m and Horizontal 150-200m cam facing me.
Vertical 150-200m and Horizontal 50-100m when drive towards cam facing away.

fyi, the fixed redflex outside 626 Coatsvill-Riverhead HW is not in the Uniden R7 database

This one is already in my V2.10 release. Built as -36.73802, 174.62157 with 80 km/h limit set to all directional alert as no other roads for false alert.

Thanks go to @josh521 for the testing on this earlier:

Here are the notes in the V2.10 build file for this:

** No camera on google. Leave for now but needs future review. Close to position marked on google earth
** However, josh521 commented “Just had another drive on the road,
** coordinate of redflex pole camera on coatesville-riverhead Hwy should be -36.738022, 174.621570 instead of 571 Coatesville-Riverhead Hwy
** (someone point this as Camera on google map)”
** therefore lets correct this one:
//BI -36.73802, 174.62157,ADSP,80
** Lets check this on streetview after a google update. It would still be nice to see the camera
** lets check the final position and orientation. (15.04.2019)

I run a r3 also. Will turn that on tomorrow see how it goes
I'd be really keen to hear if that works?! Doesn't seem to make sense though you would think the K band off setting would be global, regardless of Mrcd being on or off.

Nope MRCD is on K band and on my R3 I detected Redflex stationary cameras as MRCD so be interesting if the mobile vans also can get detected as MRCD.. Would mean no need to run K band on.
Tested this against a stationary redflex camera with mrcd on, on the r7 no radar alert only GPS alerted along Hillsborough road. Auckland.

@DEMON5 where abouts near Wellington did you encounter the MRCD? I turned MRCD on (on the R3) yesterday. I got two alerts today for a return trip in the same location near Wellington on SH1 where the dodgy van often hides (-41.17149257,174.83112089). I reckon its the radar traffic mount that is the cause of my alert. I wonder if its the same with you? I haven't yet passed a redflex van with the MRCD on, so too early to confirm. I have however passed several pole mounted redflex and no alert to these with MRCD.


I also figured MRCD would not be active if K band was set to be off. Evidently given that it is alerting I was also wrong! Fingers crossed that you have found a way to detect mobile redflex with the MRCD. That would be so nice to have on the R3!

Okay, I there was a red redflex van on SH1 in Mana opposite Z energy. Passed twice on the way out, and once again on the way back home about 1 hour later. No alerts for MRCD on the R3. Possible it was just not running at these times, but not looking promising. I did get about a total of 5 false alerts on MRCD at other locations along the route though.

The brand new R7 I got has now been updated for NZ GPS (V2.10 / 23 April 2019) and ready for its new owner. It is currently available on trademe, but I'm acceptable to any offers from forum members at a discount.

Yeah MRCD is a no from me to. A lot of falses and doesn’t pick up redflex vans. I’ve started using user marks where they normally are here in Auckland. I will contact you later in year @Mithheru. I’ll be keen for a r7 closer to Christmas.

I don't think they do that anymore. They used to ration film stock on the old cameras, the Redflex units just bang away all day.

On the subject of mobile redflex, I would quite like to build a tracking system! I wondered about making a small little tracking device that could be magnetically attached to underside of the van somewhere. Arduino nano is so cheap, and GPS is only around 10$NZ. I just need to think of a cheap way to power it, and how to transmit either radar to warn oncoming vehicles or else to somehow get it to connect to WIFI to send its GPS coordinates! Anyone got any thoughts/ideas that might help!?

Feed back R7 124.124.111 K segmented NZ version.
Now I have user muted the few auto doors that were in the redflex range, I forget its on until I pass a fixed pole or get a red light warning.
Still get a big hit on K from trains and occasional K from what I think is Audi and a Ka that lasts a few seconds from possibly a leaky detector in another vehicle.
Pole mounted cam facing me im getting a K alert before the gps warning.
Pole mounted facing away the gps alerts first but It looks like the voice alert is over the K alert as K is 3 bars during voice and alerting when voice message finishes.
When I find a van i will do some vid runs past it and post.

Turned of K and tried MRCD against pole. No warning at all.

Sounds like jail for stalking the police :oops:

@Mithheru - Is it possible to use your GPS database 2.1 in updating the R7 Au/NZ version from 1.37, or do I have to wait for Blulink to do it and manually mark locations in the interim?

How far is your GPS alert? I have selectable 400, 800, 1600 metres.

400m
Seams to be a diameter so 200m each side.
Edit; R7 I have no where to select warning range on GPS, just on and of, my distances are from real life testing.

The maximum range on the GPS should be 300m on the R3 / R7. So total of 600m diameter. With blulinks V1.37 there really are not so many locations where you'll get the full 300m warning from either direction. Therefore perhaps indicate the range on the GPS alert when assessing the R7 K radar detection.

In Australia database building, we found some situations where we would get false alerting even taking into account the 300m and directional alerts. Uniden has made a good call to limit GPS range to 300m otherwise in city centres etc, you'd get many false alerts.

Also note that the GPS quoted range is not very accurate as it depends upon resolution of latitude / longitude as well as the actual alert GPS position set for the camera in the database. If you really want to establish the range best thing to do would be to use your dashcam recording at 30 frames a second. Then review the footage for the exact frame the alert is recorded, and then either go measure the distance from there to the actual camera, or use the combination of your driving speed and the dashcam recoding frame rate and number of frames to calculate the distance.

I wouldn't be comfortable with 200 metres, considering where they put pole mounts. On the other hand 200 is a bit much for RLC's.
