It's a growing trend worldwide. Once they realised there are machines that can automatically issue fines, it was a no brainer!

I really do need the gps coordinates in digital format, as well as the speed limit and directional alert where possible. I don't really have time to review all the data and decide what to add and where.

Does your v1.04 version include Uniden's July 4th update also?
Yes it does. Everything from V1.02 onwards includes that Uniden Update.

@UnidenSupport This thread is becoming quite a useful focal point for reporting the gps updates. I am happy to keep providing this service, but it seems likely that Uniden and I are independently probably duplicating a lot of work. Whilst it is beyond my capability and scope for this project to implement a more automatic way for people to collect and submit the data, I wonder if Uniden might be inclined to consider to help accomplish this?

Previous it was suggested for example that there could be an easier way of reporting the gps updates, e.g.:

Your service to the community is indeed appreciated. However, the better, easier implementation of this effort would be using GIS. I don't operate in the free Google Maps / QGIS World so I wouldn't know how to do it without some research put into it. But in the ESRI ArcGIS world, I would create a simple ArcGIS Survey123 field form, with mandatory drop down menus covering the details you present in your first form. These would get posted to the map within 30 seconds or so. On the back-end you can download the database on a weekly, bi-weekly or monthly basis as your time allows, merge it with the existing Uniden database and post it for us to download. With your mad skillzzz, you surely would find a way to filter out duplicates and in doing so remove Uniden's entries that have dated or wrong information such as speed limits. This way we would have our own community-developed "Waze-like" database of end-user reported cameras.
I am therefore wondering, if perhaps Uniden and I could together provide an easier way of collectively update and revise the gps data for these detectors? This would make this reporting system much more open and in many ways better than escorts system since the updates are reviewed in more detail.

My systems are now automated to incorporate and format the data into the correct binary format. Currently, when I have the new gps data (in digital gps format) it typically just takes about 5 minutes to rebuild the entire binary file incorporate the new data, and reupload it back on here. Therefore if Uniden could provide a simple system for collecting the gps data in digital format (e.g. see my first post here), it really is no trouble for me to provide those regular updates. I am also not charging for my time/service, since I've already done most of the hard work.

Incorrect Speed Warning in both directions at the following location. There isn't a speed camera anywhere in the area. I'm running R3 with firmware v1.50 and getting the same false report with db190402.bin and the latest db190704.bin

32.428470, -96.228700

Okay, thank you for the update.

The database currently shows two monodirection alerts in that location set to 35 mph:
These are located at 32.4290619,-96.2280731 and 32.4275818,-96.2297211. Therefore I have marked these two for deletion.

There is also one other camera alert in the database close to this position at 32.4313202,-96.231163 (set as 15 mph monodirectional alert). Before I complete the build, please could you confirm whether this one also needs to be removed.

Thanks,

M.

Confirmed, nothing there in either direction.

Perfect timing! I checked this morning on my way back to Dallas from my weekend place at the lake.

Thanks

GPS data limit?

I'm guessing nobody knows the answer, so, I've decided I want to test the gps memory capacity of the Uniden detectors. My code has predicted the maximum limit is 65536 camera alerts. So far, the biggest file that has been tested on an R3 is the European database which has over 13,000 alerts. Just think if the prediction is correct, you might be able to get the entire world onto a single detector!

So, I built a complete gps database file ordered by latitude as per the Uniden standard US binary data format, and filled with random dummy gps data from around the world, and containing all 65536 alerts. All tested version of the R3, R7, DFR9 and DFR7 upload tools all accepted the file without complaint. However, I have not yet dared to upload such a big file as I don't want to risk my R7. Therefore I plan to use a DFR7 to test. I will build bigger and bigger files with more and more memory blocks of gps data, until either the DFR7 dies or I reach my predicted limit.

However, @UnidenSupport might already know the answer. Could you please confirm my prediction before I subject a DFR7 to potential destruction?

Sorry, that was probably not a fair request / comment. This information is also probably not something that needs to be known generally. I also now consider that perhaps some of this memory allocation could also be used for other purposes such as user marks and gps lock-outs, so it might not be so clear cut an answer anyway. It would however be useful to know the memory capability of the detector, as I don't really want to overload it. Especially if the upload tool was not contemplated to handle such large files. Trial and error probably the way forward.

I generally do test all developments before release. My code also now independently verifies all the data during the build process for compliance. This ensure it all falls within the known parameter limits (hence my query of the memory capability).

Looks like there's a non-existing speed cam alert here going in going in both direction along 695.
