Which factor is critical when using protective lighting in security measures?

The intensity of light is critical when using protective lighting in security measures because it directly impacts visibility and the effectiveness of the security system. High-intensity lighting can deter criminal activity by enhancing visibility in dark areas, making it more difficult for potential intruders to conceal themselves. Properly illuminated environments allow for clear observation and identification of individuals, which is essential for maintaining safety and security.

Moreover, increased light intensity can minimize shadows where intruders might hide, reducing the risk of unauthorized access to facilities. Choosing the right intensity also involves considering factors such as the specific environment, the nature of the potential threats, and the objectives of the security measures being implemented. Effective protective lighting helps to create a safer atmosphere and enables security personnel or surveillance systems to perform optimally.
