  Video surveillance systems are increasingly used in different fields, from
the domestic to the commercial environment. Current systems are being improved
and complemented with new elements and functionalities. This paper proposes the
design of a video surveillance robot based on Raspberry Pi with the abilities
to perform tasks of motion detection, send video on real time, fire detection
and also, the possibility of control it remotely from the Internet. In order to
check the information received from the robot, as well as the video sent, a
client application has been developed to any device with an Internet
connection. In addition to this, in order to protect the information obtained
by the robot, a secure system is proposed, which uses different security
mechanisms to achieve this goal.
