The fields of application of machine learning algorithms have no limits thanks to the focus of scientific research and its great impact on comfort in our daily life. Basically, with Artificial Intelligence (AI), the computer has become able to do tasks that were impossible in the past. The image processing strength and performance of the computer combined with Artificial Intelligence has contributed to the emergence of a new intelligence called facial recognition which contributed to the development of surveillance camera technologies and made them more effective.If, for example, When a company installs a surveillance camera without linking it to high-tech, its performance will still be limited in case the lighting level decreases , Blackout , Gradual change of lighting. Sudden change of lighting, shadows falsely detected as objects , and so on . This is the aspect that our paper deals with: the importance of Developing intelligent software that allows a camera to learn the faces of employees of a company in order to note their entrance hours , tracking their movements in crowd .The paper will be divided as fellow : first General introduction about camera de surveillance system. Second, we are going to highlight how the Artificial intelligence develops facial recognition Third, presenting the impact of facial recognition in video, Fourth ,presenting of web application based on AI in order to enhance the system of camera de surveillance.
