Essay: CCTV camera technology-diversity
Various models of the CCTV cameras do exist. The evolution of the different models varies based on their diversity in the way in which they are used and the actual design and the scope of their coverage. The TV-PTZ2100A1/E1 model, for instance is a dome shaped CCTV camera that offers various capabilities of recording video images. This model of the CCTV camera has a very great optical zoom with a 10X point capability of zooming.
Major traditional models of the close circuit television do not have the zooming capabilities. The HITACHI WDR closed circuit television cameras, on the other hand, do not have the zooming capabilities. This normally leads to greater limitation of the security regulation. Additionally, most modern CCTV models encompass the integration of wireless capabilities such as the usage of infrared lights and Bluetooth techniques. Box cameras have however shown that they are more powerful and mainly have the WDR capabilities of the camera (Koch and McGrath 1996, pp. 54-335). Some of the cameras however do not have the capacities to withstand cruel weather conditions.
