  1. The GPS signal on my Huawei smartphone gets lost every few seconds. How can I fix this?

    Please make sure you’ve downloaded the latest update 3.3.0 from your app store. Then activate the following setting in your app:

    location_services

    Menu > Settings > General > Use location services

    In case you haven’t received the app update yet, please go to your smartphone settings and deactivate the following option transitionally until you receive the update:
    location_accuracy

    The path might vary depending on the model of the smartphone.

    go to top

  2. How does the app update the speedcam data?
    The database is being updated automatically every 7 to 10 days – at app start and given a stable internet connection.
    The database for mobile speedcams and dangers is being updated automatically every 5 minutes via the internet connection.
    The last update and the current amount of data you can check on the status information page. In order to get there, please press on the map pin (reversed raindrop) bottom right and then on the “i” that shows subsequently. The number of fixed speedcams and dangers should be at least 91.000 (as of Mar ’19).
    go to top
  3. Why does the battery drain even though a charging device is connected?
    We have tested several charging devices and have come across the phenomenon that not every charging device actually recharges the battery when apps are still running on the smartphone. We assume that inferior components in charging devices are responsible for this as the problem mainly occurred with cheap charging devices (including preinstalled charging trays in cars). Our tests show best results with original chargers by Apple and Navigon. These recharge the smartphone battery effectively while CamSam/Blitzer.de is running. There are four triggers which, combined, can cause a relatively high power consumption:
    a) The display is illuminated constantly
    b) The GPS-receiver continuously locates your position
    c) The app persistently calculates the distance to nearby cameras in your driving direction
    d) Roughly every 5 minutes the app connects to our servers in order to retrieve the latest mobile camera and danger data. In addition, when using the map, CamSam/Blitzer.de (PLUS) loads map data
    e) There are apps running in the background, even though they are not being used in the foreground.
    Every other app would encounter the same issue under the same circumstances.
    Thus we recommend to:
    a) Use a premium charging device
    b) Turn off the display once in a while and/or choose the Black Mode (Settings > General)
    c) Not to use too many apps at once and close unused apps in the background

  4. The app cannot determine my location (red satellite symbol). How do I adjust my location services (GPS settings)?
    See No GPS, searching for satellites – Problems with location services
    go to top
  5. Why doesn‘t the app optionally show currently inactive mobile camera spots?
    We have considered the implementation of inactive mobile cameras but have decided against it. One reason against the display of inactive spots is the enormous data traffic this would cause. The database of active mobile cameras is manageable and the database for fixed cameras contains approx. 90.000 spots which is still OK. However, there are 500.000 inactive mobile spots … and we’re still counting. You would hear a beep at each and every corner andconsequently deactivate this feature.
    go to top
  6. Why doesn’t my app show all fixed cameras?
    Presumably, the database for fixed cameras did not load properly on your smartphone. This database updates automatically every 7-10 days. This update however only takes place under the condition that the internet connection is steady and non-disruptive during the update process. The quality of the internet connection varies locally. Our recommendation: If you have wifi at home, please occasionally start the app home (in the mornings/prior to your drive) for the databases to load correctly. After approximately 10 days the data base for fixed cameras should be up-to-date. The number of fixed speedcams should be at least 91.000 (as of March ’19).
    go to top
  7. How can I report a speedcam/danger later?
    If you did not have the app at hand or if you noticed a speedcam danger too late, you can get in contact with our editorial staff. From Monday to Friday 8 AM till 7 PM you can reach them via WhatsApp chat: 0170 6000 110.
    For your report to be processed quickly, please give precise information such as exact location, max speed, driving direction etc. Please understand that we cannot answer WhatsApp calls.
    You can also reach our editors using this free hotline: 08000 50 51 52.
    Please use these numbers for danger reports only. In case of technical issues with our app please write an email to info@blitzer.de. You can also phone the technical support: +49 49 696 56 192.
    go to top
  8. Does the app alert me of Section Controls? What does the orange blinking „SC“ symbol mean?Of course CamSam (PLUS) will also alerts you of Section Controls. These record your average speed on a longer section. We show the usual danger sign for the beginning and the end of the section control.In addition to these you’ll see a blinking SC in the upper right corner. It will be blinking for 60 seconds at the beginning and the end to signal that it’s not a usual speedcam.go to top
  9. How much data volume does the app consume?
    We recommend that you use the CamSam/Blitzer.de in combination with a data flatrate. Approximately every 5 minutes the app will load 50 kB (less at night). This is equates to ca. 600kB and 14MB per day (24hrs permanent usage of the app). The data volume consumption depends on the number of cameras in the database. The fixed camera database will automatically be updated every 7 days (*only if you start the app and the internet connection is steady). This consumes ca. 4MB.
    go to top
  10. How can I report a fixed camera via the app?
    The fixed camera locations are imported from our SCDB database. In addition, you can report a fixed camera in our app. Alternatively, you can report them via our website http://www.Blitzer.de and add the information that it is a fixed camera. Our editorial department will treat this report separately. You can also send us an e-mail with detailed information about the fixed camera (type, location, direction etc.) to SCDB.info via gps@scdb.info or the report form
    go to top
  11. Why are there false reports? How are these locations deleted?
    The deletion/deactivation of active mobile cameras on our website works as follows:
    a) reports made by users/via website/hotline etc. deactivate automatically after 3hrs
    b) the editorial staff can delete the reports manually if there is a concrete reason
    c) app reports via the app are deleted automatically after 3hrs max.
    go to top
  12. What does the feature „seen (thumb up)/not seen (thumb down)” entail?
    You can give us feedback, immediately after you’ve passed a mobile camera spot, if you’ve seen the camera or not. Your feedback helps us in finding false reports and inactive camera spots and deleting them from our system. If a report receives a certain amount of poor feedback (predefined quotient) it will be deleted from our system, so subsequent users won’t get this report anymore. You should be aware of the fact, though, that mobile camera spots might be located on the opposing traffic lane! If in doubt, it is better not to give a feedback at all.
    go to top
  13. Direction-dependent alerts for mobile cameras?
    Currently, only for fixed cameras direction-dependent alerts are given. In the case of mobile cameras it is safer and more effective to have more reports. For one thing, the reporting during driving should be as easy and quick as possible (too many settings would be counterproductive). For another, errors could occur if users accidentally gave us the wrong direction or did not notice that there were cameras located on both sides of the road).
    go to top
  14. What does the number of users mean?
    In almost all versions of CamSam/Blitzer.de a number of users is shown. The first number shows the number of active users that are currently using the app (at a given point). By tapping on this number the display changes to the number of users in your surrounding area. This surrounding area is defined as a circular radius with a diameter of 50 km or a radius of 25 km (from your current position). This value has an informative character and cannot be changed by the user.
    go to top
  15. Why don’t I get any acoustic warnings (Bluetooth active)?
    Both smartphones/tablets with iOS and Android have implemented Bluetooth-protocols HFP (HandsFreeProfile), HSP (HeadSetProfile) as well as A2DP (Advanced Audio Distribution Profile). The first two profiles allow you to make phone calls via the Bluetooth connection; either via a hands-free device or a headset. The A2DP profile is responsible for the transmission of audio files.
    All audio alerts that are given by the app are audio files. In order for them to be transmitted via Bluetooth, the device that needs to be connected (usually multimedia systems in cars) must have an implemented A2DP profile. Otherwise, the playback of audio files via Bluetooth connection is impossible. Multimedia systems that currently do not have implemented A2DP profiles are Audi MMI and BMW Navigation System Professional, among others. In these cases please force the audio output through the speakers of the smartphone/tablet. If this audio output is too quiet, please read the following section.
    Note to iPhone users: Please make sure you have not accidentally activated the mute button on the side of the iPhone.
    go to top
  16. What can I do to increase the volume of audio alerts?
    In all smartphones there are several volumes, that have to be adjusted independently from each other:
    1. The volume of the phone ringing;
    2. The volume of each app;
    3. The volume of media playback (audio/video).
    While the app volume can be adjusted in the app settings, and the volume of the phone ring is irrelevant for the playback of an audio alert, the regulation of the media volume of the app is not that obvious.
    Since all acoustic warning sounds are audio files, you need to adjust the media volume in addition to the app volume. You can do this while you hear the alerts. As the duration of these sounds is short, you better adjust the media volume while playing back music in a music player app. The volume set for media playback will be used by CamSam/Blitzer.de as well.
    go to top
  17. Why are some reported cameras not shown on the website?
    The app and the website operate with two separate databases. Not all cameras that are in the app database will be displayed on the website http://www.blitzer.de. We have set some filters to minimize the number of false reports.
    go to top
  18. Why doesn’t the website open on my smartphone?
    The website http://www.blitzer.de is not optimized for smartphones. Therefore you cannot open it with a smartphone browser. Please use our app for your smartphone to receive camera alerts or report them on the road.
    If you don’t have an app-compatible smartphone, alternatively you can use our CamSam/Blitzer.de WEB App. Please open app.scdb.info in your smartphone browser. Note: You need a browser that supports HTML5 to run this web app!
    go to top
  19. Is the app also available for Symbian /bada / Windows Mobile?
    Symbian was an operating system that was only used by Nokia. Since the acquisition of Nokia’s smartphone division by Microsoft there haven’t been any smartphone releases for Symbian smartphones. The „Nokia Ovi Store“ that contained the CamSam/Blitzer.de app, among others, had closed. Following the app store closing there is no possibility to install new apps. Apps that have already been installed partially don’t work either due to expired licenses. We are not going to develop an app for bada as we are currently busy with other operating systems. In addition, we want to see what role bada will play on the smartphone market anyways. We won’t develop an app for Windows Mobile® 6.5 since we already have one for the subsequent operating system Windows Phone.

  20. Which alert symbols might appear?Below you’ll find a short overview of symbols that might appear on your display while using the app. In each case, the symbol inside the circle or triangle is crucial; variations – depending on the operating system and types (e.g. mobile and fixed) – are possible.Safety Cameras & Traffic Control

    go to top
  24. ANDROID: I have activated energy saving modes. How do these affect my app?
    In order to work properly, our app needs access to your phone’s location services, the internet and the phone memory, among others. If you’ve restricted the access, in some cases it won’t work corretly. One of these restrictions might be the energy saving mode. This might prohibit the app from accessing the location services in the background. Please make sure you don’t have any restrictions active.In the following are examples of two different smartphones to show you how these settings that need be changed might be called. The exact names might vary from one phone to another. Our app should not be „optimized“ by your smartphone.

    manually

    Ex. 1: Huawei P20 PRO, Android 9.0: Go to Settings > Battery > App launch > > CamSam/Blitzer.de PLUS should NOT be Managed automatically but „Manually“.

    special_access

    Ex. 2: Huawei P20 PRO, Android 9.0: Also, go to Settings > Apps > Three dots > Special access > Battery optimization > >Gehe bitte zusätzlich zu Einstellungen > Apps > Drei Punkte rechts oben > Spezieller Zugriff > Battery optimization Not allowed > All apps > CamSam/Blitzer.de PLUS Don’t allow. Only this way you can make sure that the app isn’t negatively influenced by optimizations.

    protected_apps
    Ex. 3: Samsung Galaxy S8, Android 8.0:
    Please go to Settings > Device Maintenance > Battery > Unmonitored apps and please add our app in case it’s not yet listed there.Since the setting can be called differently from phone to phone, here’s another example from another phone.unmonitored_apps
    Ex. 4: Honor 7, Android 6.0
    Settings > Advanced settings > Battery manager > Protected apps and add our app there.

  25. ANDROID: What functions do the phone buttons have (activate background mode)?
    Android smartphones usually have three or four buttons. In general, by pressing the home button you return to the android surface without closing an app. The app continues running in the background. The back button closes an app if the ultimate/highest plane is reached. I.e. if you start CamSam/Blitzer.de and subsequently tap on the back-button, you’ll receive a confirmation pop up asking you about the closing of the app.
    go to top
  26. ANDROID: What do the various changing colours of the CamSam/Blitzer.de icon in the status bar signify?The CamSam/Blitzer.de Icon appears in the status bar after you’ve pressed the home-button of your smartphone and have made the app, thus, switch into the background (see previous question). When you’re using our app while on the road and everything’s fine, i.e. your GPS position cam be determined precisely and your internet connection is perfectly fine, the CamSam/Blitzer.de symbol will be green. When red, the app is trying to alert you of the fact that the GPS signal weak and your position cannot be determined accurately enough (for more, see „No GPS, searching for satellites – Problems with location services“ If your internet connection is insufficient, the icon will turn grey.
    go to top
  27. ANDROID: Is CamSam/Blitzer.de compatible with Android Auto?
    With Android Auto, several functions of the Android smartphone can be controlled using the communications system of your car. The compatibility list of apps is compiled by Android and, unfortunately, CamSam/Blitzer.de is not yet listed. However, CamSam/Blitzer.de still remains available to you, even during the usage of Android Auto – and here’s how: Please go to app-settings Sound > Audio output and choose the Bluetooth profile „Bluetooth A2DP“. Subsequently, press the sound-test button (while in the car) in order to make sure that the connection has successfully been established and the acoustic warnings are reliably given by the audio system. (Tested with Pioneer avh-x8700bt Radio)

  28. ANDROID: The app signals „No GPS“ in the widget/background. Which settings need to be adjusted?By pressing the home button or turning off the screen, you can send our app from the fore- to the background. The continuation of the work in the background is only granted if the app doesn’t experience any restrictive settings. Please make sure our app doesn’t accidentally slip into these restrictions. Please see here for advice FAQ #20.
    go to top
  29. ANDROID: How do I close the app automatically (e.g. with Tasker)?
    The Broadcast-Intent to close CamSam/Blitzer.de automatically is as follows: de.blitzer.KILL_APP . This Intent is available from version 2.5.1 onwards.
