PY103.16 Physical Security Practice Test

Exterior security lighting should be designed around recognized guidelines to provide consistent visibility while controlling glare and supporting security objectives. Following lighting design guidelines helps set appropriate illumination for each area, ensures uniformity so there are no dark pockets or harsh transitions, and avoids glare that can blind people or wash out camera footage. This approach strengthens security by improving detection of people and objects, aiding guards and surveillance systems in identifying faces or license plates, and deterring concealment. Relying on aesthetics, lighting only at entrances, or blasting brightness everywhere misses the need for balanced, area-specific illumination, can waste energy, and may create glare or overexposure for cameras. Instead, plan lighting for all critical zones—entrances, perimeters, walkways, parking, and loading areas—so visibility supports security while remaining efficient and comfortable.
