A. Lighting: * Deter: Intruders are less likely to attempt a break-in if an area is well-lit, as it increases their chances of being seen. Detect: Bright illumination makes it much easier for security guards or CCTV cameras to spot and identify an intruder who does attempt to enter. C. Signage: * Deter: Signs like "Warning: Armed Response" or "No Trespassing" warn potential intruders of the consequences, discouraging them from proceeding. D. Sensor: Strictly a detective control. It alerts you to an intrusion, but it cannot physically stop someone or act as a visible deterrent unless paired with an alarm or light.
Lighting Preventive/deterrent: Illuminates areas to discourage unauthorized activity. Detective: Enhances visibility for security cameras or personnel, making it easier to identify suspicious behavior. Sensor Detective: Detects motion or unauthorized access, triggering alerts to security personnel. Deterrent (indirect): If intruders know sensors are present, they may avoid the area.
