After we made Zipcar, we though about expanding this system. Current Zipcar system is working with radio signals, but I wanted to make system that works on internet.

So, first work is to make video streaming service that works on internet.

Hardware: Raspberry pi, Raspberry pi camera(this is not webcam)

If you search on the internet, you will see many webpages that uses ‘mjpg‘ method. Actually I tried two methods

1. mjpg-streamer library
2. mjpg method without using library(article),

But both methods had too much latency. It was about 4~500 ms. Too much for real time control system.

Luckily, I saw this article and some people said that ‘gstreamer‘ is much faster(in the comment).

So, tried gstreamer. I wanted to write how to use gstreamer. However there is already wonderful video in youtube.

After I used ‘gstreamer’, there was no latency.

Thanks to Brynlea Gibson. Her video helped me a lot. There would be no problem if you just follow this video.

Result: Better to use gstreamer rather then mjpg-streamer, if you need low latency system.
