4 To mount your Smartphone as a dashcam (Window mount from Mobilefox) (optional) a License Plate Camera and a USB Video Grabber (optional & Raspberry 2 or higher provided) + (EasyCAP USB Audio/Video Grabber Fushicai UTV007 chipset) 4

The output of your car charger should have 5V and the recommended current capacity

5 List of all Raspberry Pi s (April 2017) Please make sure that your Raspberry gets enough power and the right Voltage. The output of your car charger should have 5V and the recommended current capacity for your model is written on the list. To mount your Raspberry & camera in the trunk you can use this car mount tape. HPX ZC0025 5

6 Configuration WiFi Hot-spot A network is needed to get a connection to the Raspberry Pi. In this example we use the Hot-spot function of our Smartphone or Tablet to get all devices connected. Go to Settings More Tethering & portable hotspot Set up your WiFi Hot-spot with a Network name and Password and save it. Automate WiFi Hot-spot ON/OFF in car (optional) If you want to automate the activation of your Hot-spot when you get into your car and turn on the ignition, there is a good app to do this. Download and install Automate from Google Play Store The next steps works only if you have a Bluetooth radio in your car. 6
