Using a CCTV security camera in various places within a business has made protecting the company’s assets much easier and provides the evidence usually needed for successful prosecution. Depending on the type of business and its size will determine how many cameras will be needed as well as the types of cameras in use, and installation should be supervised by someone knowledgeable in closed circuit television systems.
Most businesses will want a video of customers and others as they enter the business and a CCTV security camera with an automatic aperture will be needed if the business hopes to have a usable image. Manual aperture settings might provide a good image at night, if the aperture is open wide enough but during the day when the sun comes out, the image will be washed out and useless. Resetting the manual lens for a good shot during the day will result in a shot that is too dark at night making the individual unrecognizable.
Anywhere a CCTV security camera is placed by a door or window there the available light is likely to change significantly should be equipped with an automatic lens. All of the CCTV security cameras should also be fitted with auto-focus lenses so that no matter how far the subject is from the camera, they will remain in constant focus.
