This paper presents an experimental work on video surveillance system which is capable of monitoring a desired room for security purpose. The system will continuously keep track of particular location with help of camera installed and obtain database of image frames from video. Adjacent frames are compared for scene change and upon successful detection it will notify remote device such as mobile which is wirelessly connected to central system. Image compression techniques are used to utilize storage or transmission efficiency. Scene change detection is based upon MAFD (Mean Absolute Frame Difference) and Histogram equalized MAFD. Transform domain and spatial domain techniques are used for compressing the video frames.
