A dash cam using raspberry pi and rpi camera, long-duration recording without frame drop

Raspberry pi Dashcam

rpi dash cam uses raspberrypi + rpi camera to create your own dashcam. It supports button control and LED indication. Very simple and minmal code. Most importantly, it has no frame drop!

During recording rpi dash cam requires very little CPU and memory source, it uses techniques like Theading and Event Queue to handle the workload between capturing and buffer saving. Thus solves the frame dropping problem many people are facing when recording long-duration video.

Tested on RPI3 model B with rpi camera V2. Demo video.
