usb_cam_driver and usb_cam_resource

Overview

This driver is able to driver a usb cam. The pictures which are taken are stored on a NAS. That is done, because i want to share them between nodes.

Setup

Before you can use the driver you have to install streamer

sudo apt-get install streamer

Configuration

In your things.config file you have set activ to true and you have to configure the path to the photo store. In my enviroment i set the path to /home/pi/photos

[{path, "/home/pi/photos"}, {last_shot, 0}]

last_shot is used internal and stores the time when the last photo is taken.

Raspberry Pi -> Synology NAS Setup

In my env i have a raspberry which takes the photos and an raspberry which host the web applications. So, i had to do the following step on both machines.

Follow the instructions to setup the NAS : NAS

In your /etc/fstap file you have to insert the following line.

IP_OF_YOUR_NAS:/volume1/usbcam /home/pi/photos nfs nouser,rsize=8192,wsize=8192,atime,auto,rw,dev,exec,suid 0 0

and then you can mount it with :

sudo mount -a -o nolock
