"Speedometer Radar Camera" detects road signs using the camera while driving. It displays your current speed with a speedometer along with the last detected speed limit. Color and sound of the speedometer indicate when you are too fast. This makes Speed Limit warning Camera a very useful driving app always showing current speed with the speedo and current limit. It recognizes over 40 road signs.

► Working principle of Speedometer Radar Camera
Speed Limit warning Camera is not considered to always display the current speed limit at any time and place, instead it is a road sign recognizer for selected road signs. These signs are shown in the App Store. This means that e.g. within a town the default speed limit is not displayed because there are no road signs for the default speed limit. Please bear that in mind when using Speedometer Radar Camera app. Also please read the liability disclaimer below. The speedometer gets it's data from the GPS and is used to determine wether you are above or below the actual limit of the last detected road sign.

► System requirements of Speed Limit warning Camera
Speedometer Radar Camera requires an iPhone SE, 6 or higher running under iOS 10 that must provide the extension 'Metal Performance Shaders'. There is no support for iPhone 5 or lower and there won't be in the future due to hardware constraints.

► Limitations of Speed Limit warning Camera
Speedometer Radar Camera does a computational intensive job that formerly was limited to mainframes. Therefore there are some restrictions:

- At night and in adverse lighting conditions the recognition of road signs might fail due to iPhone camera limitations.
- The app is optimized for German road signs. However in many countries the signs are very similar and therefore the app should work there too. Unfortunately there is yet no support for US speed limits.
- There is no support for 'end of limit' signs yet and no support for place/city signs that might also decrease the speed limit according to local traffic road regulations.
- Sometimes road signs in narrow turns are missed due to the limited view angle of the camera
- Sometimes there are missed or false road sign detections
- Speedometer is updated every second

Need 110km/h speed limit detection

This is quite a good app, and reasonably reliable for what it is trying to do.
I am using it in Australia, and it does not seem to recognise the 110km/h speed signs. Instead it tells me the limit is 10km/h!
The 110km/h speed limit is the standard limit throughout Australia for motorways.
Can 110km/h be added in a release soon, or is it already there and something wrong with my setup?

Sometimes v useful

When the app picks up the speed sign it is great. Speedo pretty accurate. Would be excellent if I could select the speed limit in the speeds at the bottom of the screen when it misses a sign. This would help a lot at night when it doesn’t detect the signs at all. The little green circle seems to detect signs, but doesn’t change the speed environment. The camera doesn’t always focus either, which makes it hard to detect the speed sign. With a few tweets this would be perfect.

Excellent app, it could do with a different sounds and I can’t find speed signs to configure.
