 +
 +Compile the mjpg-streamer
 +
 +  $ cd mjpg-streamer
 +  $ make
 +  $ sudo make install
 + 
 +
 +Run a test.

 +
 +If the MJPG-streamer needs to be started automatically at system startup, you can create the configuration file /etc/init/mjpg_streamer.conf for Upstart :
 +
 +
 +  description "MJPG-streamer /dev/video0"
 +  start on runlevel [2345]
 +  stop on runlevel [016]
 +  script
 +     /usr/local/bin/mjpg_streamer -i "/usr/local/lib/input_uvc.so" -o "/usr/local/lib/output_http.so -w /usr/local/www/www" >> /var/log/mjpg_streamer_upstart.log 2>&1
 +  end script
 +
 +The script for starting a multiple cameras:
 +

 +Kui remote masinas pole enne tehtud, siis teha esmalt kataloog:
 +
 +  mkdir .ssh
 +
 +Kauglabori veebiserveris www-data kasutaja alt:
 +  sudo -s
 +  su www-data
 +  bash
 +
 +
 +(kui korra juba tehtud võib vahele jätta)
 +  ssh-keygen -t rsa
 +  cat ~/.ssh/id_rsa.pub | ssh [remote-kasutaja]@[remote-masin] "cat - >> ~/.ssh/authorized_keys"
 +Kui key olemas, aga vana host, siis teha enne remove, nt:
 +  ssh-keygen -f "/var/www/.ssh/known_hosts" -R usora-artica.noip.me
 +
 +Kontrollida, kas remote host õigused on paigas:
 +Kataloogi õigus:
 +  chmod 700 ~/.ssh
 +faili õigus:
 +  chmod 600 ~/.ssh/authorized_keys
