When laying out and designing a video security system, the first consideration is the placement of cameras. Yet one of the most overlooked aspects of the design and installation of many video security systems is exactly where the focal point will be and precisely what the camera will see. Although the placement of cameras is all about the object or viewing area, end users must consider many factors to get optimum system performance.
Camera-view position and how it relates to overall system performance is a function of many considerations. Object focal point and distance, camera elevation, direction of the camera lens, viewing angles, lighting and the end user's own perceptions are all critical factors in system design.
