A systems administrator is reviewing a proposal for security camera installation in a data center. The primary objective is to monitor and record all physical access attempts to the server cabinets. Which of the following represents the MOST effective camera placement strategy to meet this requirement?
Focus camera coverage only on the main entry and exit points of the server room.
Position cameras to create overlapping fields of view, ensuring there are no blind spots along the fronts of all server cabinet rows.
Install pan-tilt-zoom (PTZ) cameras in the middle of each aisle to allow security personnel to track suspicious activity manually.
Place a single wide-angle camera at the end of each aisle to minimize the total number of devices required.
The correct strategy is to position cameras to create overlapping fields of view, eliminating any blind spots along the server cabinets. This ensures that all access attempts to any cabinet are visible and can be recorded. Placing cameras only at entry/exit points neglects the primary objective of monitoring the cabinets themselves. While pan-tilt-zoom (PTZ) cameras offer flexibility, they can only view one area at a time, potentially leaving other areas unmonitored; fixed cameras with overlapping views provide more reliable, comprehensive coverage. Using single wide-angle cameras can result in image distortion and may not provide sufficient detail to identify individuals or actions at the far end of an aisle.
