In my thesis I have presented the concept, history, developement and the usages of the modern video surveillance systems. I explain how the recorded video is used within the various types of aplications. There are a lot of inteligent video applications such as video motion detection, camera tampering detection, image enhancement, people and object counting, people tracking, automatic number plate recognition etc.
In the second part of the work I used an open source iSpy application to build a practical video surveillance system. I used a Philips web camera, IQEye IP camera and a Canon 1100D digital camera to make video recordings and to compare the image quality. I recorded a person who was walking in front of the camera at three different distances. In the first recording she was around 3m away from the cameras and went from one end to the other in the camera’s view. Than the distance was reduced to 2m and in the end to 1m. I analyzed the recordings and measured various parameters such as the size of the face, the height of the person etc. In the end I described the usage of remote IP cameras. I present the setup process using the iSpy and IP Camera viewer 3 applications, and then I compare their functions.
