ABSTRACT
Lighting does two main things: enhance observation and deny camouflage. It is used to illuminate interior and exterior areas and strategic locations such as entrances and loading docks. Lighting applications consider safety and security needs in determining what to light and how much to light. There are different types of light sources available for security applications. When choosing the type of light, considerations include the cost, coverage, and service. You should also consider whether the lights are going to be used with closed-circuit television (CCTV), and whether the CCTV is black and white or color. Contrast and color rendition usage will be affected by the light source selected. The power source should be configured to have lights on separate circuits. That way, if a circuit fails, you will not lose all lights. In high-risk areas, lights should be connected to the emergency generator.
