Which lighting technique is used to observe intruders at a considerable distance beyond the perimeter?

Explanation:
Observing intruders at a long distance is best achieved with a bright, highly directional light aimed outward toward the area beyond the perimeter. This glare projection creates a strong, high-contrast beam that makes a moving person or reflective gear stand out against the dark background as they enter the beam, enabling detection from afar. Flood lighting, while broad, washes out detail and reduces contrast at distance; soft lighting minimizes shadows and isn’t effective for distant detection; infrared illumination requires IR viewing equipment and is about night vision rather than producing visible glare for distant human observation.
