I have an AutoVox A118 dashcam. It works as a dashcam should, but I want to add a Pi to my vehicle to add some functionality. Two main things I want to add are GPS through the Pi, and the ability to download the video files to my home network when in range of my Wifi.

The A118 has self storage, 32 GB.

I do not want to use an official Pi camera because of the smaller diagonal angle, and because of the short range of the ribbon cable. I also do not want to use a regular USB camera as they tend to be slower and of lower quality than the official Pi camera (unless you can recommend some great option, I've seen the official USB webcam list but don't know what kind of quality I can expect).

What I intend to do at the moment is to record the video with my A118 onto the mounted storage, and when home use the Pi to access those files and transfer them over Wifi.

The problem I am having now is that this camera, when first connected to either my PC or my Pi the camera asks whether it should act as a "Mass Storage" or "PC Camera".

Selecting "Mass Storage" on the camera, it acts as a regular USB flash drive, where I can access the files on it, but it cannot record. And when it is as a "PC Camera" I can record with the camera (have not tried using it as a regular webcam, but don't intend to use it as such with the Pi because of the lower quality video.

How can I interface the Pi with this camera to where I can control when it records, but record to the camera's storage, and access the stored files when needed?

    This question is not specific to the Pi - most Linux systems would be the same. You may get more answers on unix.stackexchange.com (delete reference to the Pi camera, which is irrelevant). – Milliways Apr 10 '18 at 3:35
  • The internal storage likely requires a special driver for the camera to store directly to it while being used as a camera. Sometimes such devices provide both mountpoints at the same time – crasic Apr 10 '18 at 6:21
  • @crasic Do you mean the camera could be mounted both to write to the sd card, and to the computer at the same time? Could you explain a little more, or point me to a reference of the concept, it's the first I've heard of this topic. – A.S. Apr 10 '18 at 12:44
