No need to install anything. Just open a terminal and execute the following command to get the temperature of your RasPi. /opt/vc/bin/vcgencmd measure_temp Automate the process The below script will automatically reboot your Raspberry Pi should it reach a specified threshold (maxtemp). First of all make sure you can reboot/shutdown your raspi without linux asking you for a password.  user@user:~$ sudo visudo Add the following to the sudoers file.  user ALL=NOPASSWD: /sbin/shutdown The script Save as temp.sh. Maxtemp specifies the temperature cut-off point, at which the Raspi will reboot.  #!/bin/bash #title :temp.sh #description :Checks Temperature of Raspberry Pi and reboots at maxtemp. #author :Mike M | www.linuxx.eu #notes :Add "user ALL=NOPASSWD: /sbin/shutdown" to sudoers file temp=`/opt/vc/bin/vcgencmd measure_temp | cut -c 6-7` maxtemp=75 if [ $temp -ge $maxtemp ]; then xmessage "Alert!

If you want to build a surveillance cam you might want to have a look at motion, but for simple video streaming I 'd go for vlc. Enable Camera Module sudo raspi-config Install VLC Media Player sudo apt-get install vlc Stream (RTSP)  raspivid -o - -t 0 -n -w 800 -h 600 -fps 20 | cvlc -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/}' :demux=h264 - w: width - h: heigt - fps: frames per second Viewing The RTSP Stream   You need a video player capable of RTSP (e.g. VLC). Open a network stream: rtsp://###.###.###.###:8554/ ###.###.###.### is the IP address of your raspberry pi. Also, do not forget the '/'  at the end, otherwise it won't work.
