Security issues are discussed nowadays at all areas
of our day life. Monitoring of objects as well as peoples (does
not matter if from good or bad idea) is needed at every place
and every time. Problem can be seen only in the large amount
of financial costs for hardware devices and needed space for
video recording. Our goal is to design and develop a low cost
solution for monitoring of various areas (view of camera),
which are needed to cover. We use a standard USB camera
attached to a PC/laptop via a USB port, or embedded laptop
camera to monitor of some space. USB camera has the task of
scanning the surroundings and in case of detection of some
movements (of people or objects) to begin a recording
operation of video stream which can be stored on a local data
store. Advantage of such solution is multi camera possibility.
Paper also deals with motion detection method description
using a differential method. Change of the input video using
the grayscale method and other adjustments associated with
the elimination of noisy areas and the preparation of imaging
to detect (Thresholding-thresholding, Erosion, edge detection)
was also used as part of the project was also used. By these
minor adjustments it is possible to achieve smaller error rate in
detection, what results in filtration of external influences (such
as weather changes).
