I think it's because they don't want to have the silicon|dollars|power budget of compressing the video. They externalise it to users having to buy stupidly big SD cards. My previous dashcam gobbled through 1.2GB for each ten minute file. There must be more to it than that. Even cheap smartphones can do realtime video compression. The hardware is probably commodity by now. |
