In this paper, we developed a concept of video monitoring system using a single mirror-drive pan-tilt mechanism. The system provides multiple zoomed videos with controllable viewing angle for each zoomed video and a wide-angle video. The system can be accessed by several users by connecting their personal computer (PC) to the server PC through the network. Every user is granted to change of their respected viewing angle of zoomed videos. The system is suitable for the remote observation deck for sight-seeing purpose. The system is composed of two high-speed cameras with wide-angle and zoomed lens, and a high-speed mirror-drive pan-tilt mechanism. The system implements a convoluted neural network-based (CNN-based) object detection to assist every user client identifying objects appearing on wide-angle and zoomed videos. We demonstrated that our proposed system is capable to provide wide-angle and zoomed videos with CNN-based object detection to four clients, where each client receives a 30 frames per second zoomed video.
