Dummy Speed cameras

Hello all,

I appretiate that Telmap is a free service, but .................!

I recently used Telemap to navigate a route from a rural location in Northamptonshire to an address in Birmingham (UK), which took me along the M40 & M42 motorways.

I lost count of how many times the satnav advised me of a dummy speed cameras, all of which were not there (or signs of ever being there) and most of which were on the motorway.

It got that bad, that I turned off the audio until I reached the outskirts of Birmingham, where I re-activated it.

Also, the over-head gantry cameras at the junction if the M40 & M42 were listed as dummy cameras - which they're not!, they are very real and active!

As I mention, I know its a free service, but it drove me to distraction leading me to turn it off!!

Wots going on?

They are linked to the variable speed limit cameras that control the flow of traffic on the M42 near Solihull and the NEC exit

But what about all these non existant dummies that are all over the place?

Most of the boxes that look like cameras are simply empty boxes which is why they are called "Dummies" you won't get caught by an empty box and as its not a camera it has no place in a Speed Camera Database.

The dummy markers on the map are simply there to act as an aid meaning we know there is a box at that location but no camera (even if the empty box "looks" like a camera) - Mike

Why your software is warning of you dummy cameras is down to the supplier of the software, I don't get warnings for the dummy cameras using the PGPSW database on the devices I choose to install the data to - Mike

I know - that why I came to add a post here as I thought this was the place to advise on issue with Telmap.
If I'm wrong, I appologies, but in the past, any issues I've had with Telmap, they have been sorted here.

Just checking mate. Very Happy

Data from other sources can be a bit variable Rolling Eyes

MaFt. Are dummys included in the download data? I assumed that they weren't

Correct - dummies aren't included in the database downloaded from PGPSW. I travel along the M42 nearly every day, (J5 - J7), and I only get warned of one camera location in each direction (immediately north of J6).

dummy's are not included with the downloads because they're not cameras. the markers are shown on the submission map in abid to reduce the number of submissions we get sent in.

these particular dummies are spot on as we have had it confirmed many times by a local verifier with detection equipment and also from the company that handles the cameras on behalf of the Highways Agency.

all of this is academic though as the original poster is referring to the Telmap database and not ours.

Hang on... there's some confusion here, and two different issues getting combined when they shouldn't.

Firstly, Capers, you said:

This has gathered some interesting replies - which is great to see people wanting to help.
Please allow me to clarify a point or two.

I downloaded the BIS version of Telmap X5 onto my BB 9800 - which database it uses I can't be 100% sure about, all that I do know that it uses the one that Telmap downloads via the BIS data link.

The vast majority of the dummies indicated were on the M40, not the M42; but at the Jct of M40 & M42, Telmap advised that the gantry cameras were dummies.

I have again done the same route and got the same indication (as best I can remember) so I am wondering whether something has become corrupt in the data transfer.
As a step to remidy, I will remove Telmap from my phone and re-install to see what happens.

It does seem that the false alerts that you are getting is coming from the Telmap speedcam data as isuspect that unles you explicitly download our data you won't get it.
