Final answer:
The security lighting levels rule of thumb for pedestrians and cameras is to ensure clear visibility and detection. Standards and guidelines from organizations like IESNA or OSHA can be used to determine appropriate lighting levels for pedestrians. Cameras should have optimized lighting levels to minimize issues like glare or shadows.
Step-by-step explanation:
The security lighting levels rule of thumb for pedestrians and cameras is that the lighting should be sufficient to ensure clear visibility and detection of any potential threats or hazards. For pedestrians, this typically means having enough light to see and navigate surfaces, obstacles, and other pedestrians safely. For cameras, it involves providing adequate illumination to capture clear and detailed images or footage.
For pedestrians, lighting levels can be determined based on established standards and guidelines, such as those set by organizations like the Illuminating Engineering Society of North America (IESNA) or the Occupational Safety and Health Administration (OSHA). These standards take into account factors such as ambient light levels, surface reflectance, and the speed and age group of pedestrians.
For cameras, the lighting levels should be optimized to minimize issues like excessive glare or overexposure, shadows, or underexposure. This can be achieved by adjusting the placement, angle, and intensity of the lights, as well as using additional equipment like diffusers or reflectors.
