Question

Poor accuracy of Speed Camera data Go5200


I use a Go5200.
I have used various TomTom's for years and up until the last 6 months or so the speed camera location data (and road work speed restrictions) was excellent. I have noticed recently that the accuracy is far less good than it used to be. Long standing motorway road works speed restrictions and average speed cameras are not going from the device when the road works have been long gone and new speed restrictions and average speed cameras are not appearing when they have been in place for some considerable time.
I am sure my device is updating correctly over wifi - the maps certainly update.
Any ideas anyone?
Thanks,
Julian

Hi
@JulianF

For general improvement using the Tomtom Speed Cam Database over the default settings

Use a Computer voice...
Also....
From the main screen... Tap (.... Menu) -> Setting -> Sounds & Warnings...
Set... 'Warning Type' to... Read Allowed... (Important... Needs a Computer Voice set in the Voices menu)
Speed Cameras & Hazards... Set to ON
The next 10 Setting ALL set to Always
The next 4 Settings ALL set to ON
The device will now say....
'Fixed Camera'
'Mobile Hot Spot'
'Red light Camera'
Spoken Traffic delays

Edit....
Speed Cams
If you keep a check on the Traffic-bar... The device gives you a visual Warning of the next Fixed or Mobile Speed Camera many miles before you reach the camera
Even more info if in the 'Setting menus' you setup a Wide Traffic/Route Bar

While I agree the audible warning is a little to close... If you keep a check on the Traffic-bar... The device gives you a visual Warning of the next Fixed or Mobile Speed Camera many miles before you reach the camera i.e... 10 miles in the image below
Even more info if in the 'Setting menus' you setup a Wide Traffic/Route Bar


2.5 miles ???... Where in the UK is there a dead straight perfectly flat section of road 2.5 miles long

Hi

"No" I'm not the slightest bit stupid, I'm a realist... The height of a camera in a van I would have thought was about 1.5 metres, you need line of sight to see and check the speed of the vehicle, the slightest rise or curve in the road would restrict the line of sight
Granted a Motorway bridge/gantry will give a more elevate view...

But 2.5 miles ???... Where in the UK is there a dead straight perfectly flat section of road 2.5 miles long

"The height of a camera in a van I would have thought was about 1.5 metres" is what you said sorry but sorry it doesn't matter your wrong, why do you think that the marks on a road are there? it is so that a camera in the van or on a bridge can scan your reg and work out your speed over a distance it does NOT matter if there are curves in the road as long as the camera can keep sight of you, I know this (fact)

Hi

You obliviously have no Idea how a Mobile speed Camera/Camera van works
Try Wikipedia... Radar gun
https://en.wikipedia.org/wiki/Radar_gun

You have now moved the discussion onto Fixed Cameras
The Marking on the road are for Fixed Cameras where 2 photographs are take at a precise time interval, they then compare the 2 images to see how many of the white lines the vehicle has travelled past over between the photographs... From that info they can calculate the speed of the vehicle....
