One of the difficult problems when setting up a CCTV system is choosing the right lens for your cameras as different lenses give different fields of view, and different levels of zoom. Some of the higher-end lenses also offer features such as Auto-Iris, and manual zoom/focus adjustment. Choosing the wrong lens can lead to a camera monitoring too small an area, or conversely not having enough zoom to capture events with clarity.
CCTV is covered in detail on the postgraduate-level university-accredited Security Management Stage 2 course. The next course takes place in the UK 11-22 October 2010. for details click here for the ARC website or contact Janet.
