True or False: Controlled lighting is necessary to limit brightness according to standards.

Controlled lighting is indeed vital in physical security as it can significantly impact visibility and surveillance capabilities. However, the assertion that it is necessary to limit brightness according to standards may not universally apply, which justifies a more nuanced approach.

Brightness levels are often dictated by specific requirements depending on the context, environment, and purpose of the lighting. While some standards may call for controlled lighting to ensure that areas are not overly illuminated, thus creating glare or blind spots that could hinder visibility, the necessity of limiting brightness itself can vary greatly depending on the situation. For instance, an area requiring high-security measures might benefit from brighter conditions to enhance surveillance effectiveness, while areas needing reduced brightness might prioritize user comfort or decrease the chance of detection.

Hence, the correct stance acknowledges that while controlled lighting is important for security, the requirement to limit brightness is not a one-size-fits-all regulation and may depend on the specific security needs, making the statement not wholly accurate in every context.
