Ok, I’ll start as if there were someone reading this forgotten and isolated, abstruse hideout :
Hi guys and gals ! (ahem) … I’m glad to present you an old project, trotting in my head (amongst many others that I hope to show you sooner or later). I’m speaking about motion detection, security camera etc… I’ve quite well advanced since January, yet I’ll start with the very beginning, teasing a bit my non existent audience.
To start, using the Pi to obtain a smooth streaming video wasn’t a sinecure, let’s take a look to a short video, presenting the said streaming and an auto connection to WIFI.
(MJPG-streamer + uv4l)
Since using raspistill and reading each pictures was very laggy, ~1.5fps, I investigated a bit on alternatives :
Using uv4l, 640*480 30fps :
uv4l itself uses 4% of proc, and ~40% used by MJPEG-streamer.
Concerning the Wifi adapter, I used an USB WIFI (802.11 b/g/n) adapter from The Pi Hut, RT5370 Wireless Adapter to be specific.
