<p>The final thesis named Tracking in Sensor Networks was created by the company Instrument control Sweden. The thesis work is to create a plug-in to an already developed software pro- gram, SkyView. Via the software program one should be able to control an IP-camera from AXIS, model 215 PTZ, with the appropriate protocol over a network.  An Application Programming Interface, API, was used to easily control the camera through SkyView. The interface is called VAPIX and is used to all cameras from AXIS. VAPIX sup- ports Hyper Text Transfer Protocol, HTTP, and Real Time Streaming Protocol, RTSP.  The video was sent through the camera with RTSP, thus an investigation resulted in that the protocol was best suited at streaming video. Steering commands to the camera was sent via HTTP. A small program was written, which was then integrated to SkyView. Features to be able to control the camera with the keyboard, mouse and a joystick were implemented. Zoom, bright- ness, focus and some more features were also added. The problem with the delay should be dealt with as soon as possible.</p>

This master´s thesis deals with design of security system, which transmits captured video using mobile systems. There are chosen representatives of cameras and motion sensors that could be used in the construction. The thesis also deals with the theoretical design of the transmission system, which consists of a camera, a motion sensor, an USB modem and a microprocessor, that manages all operations. There is also a proposed block diagram of a communication method. The security system is designed and tested in various conditions.

The goal of this thesis is to design a system which would allow video data streaming from a mobile device and real time playback using a standard web browser. The technological background and the implementation platform are both part of this thesis. Web Real Time Communications (WebRTC) technology was used for acquiring multimedia data on mobile device. This technology is natively supported in the latest major web browsers and in WebView component (Android version 5.0 and above). Sending push notifications from a server to a mobile device to start the streaming is done with Google Cloud Messaging technology. The resultant system allows a user to start the application on mobile device with easy web browser access. This starts the multimedia stream from device, which can be parametrized and secured by password. The benefit of this thesis is the overview of WebRTC technology and its demonstration. The IP camera implementation shows how easy it is to use the WebRTC in real applications.

Idag blir det vanligare och vanligare att system såsom kameror eller kylskåp är eller har kapabiliteten att vara anslutna till internet och kommunicera över nätet av sig själva, så kallade IoT-system. Att ett system är anslutet till internet innebär att risken för angrepp på systemet ökar, och att systemet, om infekterat, har potentialen att kommunicera med omvärlden för att exempelvis utföra denial-of-service-attacker. Detta examensarbete undersöker säkerheten hos en internetansluten kamera (IP-kamera). Målet är att identifiera sårbarheter, och om möjligt, utveckla angrepp som utnyttjar sårbarheter hos kameran, för att testa säkerheten hos systemet. Resultatet visar att systemet är sårbart för ett antal olika angrepp, främst man-in-the-middle och cross-site-request-forgery. / Today systems such as cameras or fridges with the capability of being connected to the internet and communicating without human intervention are becoming increasingly common, so called IoT-systems. A system being connected to the internet means that the system’s attack surface is increased, and the system can, if infected, be used by the attacker to communicate with the outside world to perform denial-of-service- or other types of attacks. This thesis examines the security of an internet connected security camera, (IP-camera). The aim is to identify vulnerabilities in the system, and if possible to develop attacks that exploit these vulnerabilities in the goal of evaluating the security of the system. The results show that the system is vulnerable to some attacks, mainly including man-in-the-middle aswell as cross-site-request-forgery based attacks.

The goal of this master's thesis is a creation of dataset capturing selected users' activities, network analysis of this dataset, design and implementation of method to detect selected users' activities and discussion of achieved results. 4 devices have been chosen for the creation of this dataset.

This master's thesis deals with design and implementation of system for securing and monitoring objects. The whole system is serving as an application getaway between typical TCP/IP network and heterogeneous network containing different end devices such as security cameras, microphones and some sensors (e.g. for temperature measurement). In case of detected event, the notification is created, recorded and the user is informed via administrative front-end. System can be managed from remote location and data from devices can be shown by web interface. Theoretical part of this project concerns with the analysis of different types of connecting devices and sensors and the possibilities of their usage for the monitoring systems along with description of communications protocols for each end device. The next part deals with the cameras interfaces, content analysis and connectivity with central server. Practical part describes methods and techniques used for implementation of system.
