Not always. Tag-based systems, using UWB, RFID or magnetic-field technology, detect only people who carry a working tag, while camera systems using computer vision detect people without any wearable but only inside the camera's field of view and in adequate light. Tags can sense a worker behind a rack or around a corner, which a camera cannot; cameras catch visitors, contractors and new starters who were never issued a tag. Many sites combine both: tags for the regular workforce and blind corners, cameras for anyone the tag program misses.
The full comparison is proximity detection technologies compared. A tag-based program needs process around the hardware: issuing tags at the gate, charging or battery replacement, checking that tags are worn rather than left in a locker, and a rule for visitors. A camera-based program needs clean lenses, mounting that covers the direction of travel, and a check of detection in the site’s darkest and busiest areas.
If the exposure is mixed, pilot both approaches in your worst zone. Count missed detections and false alarms separately, since a system that alarms too often gets ignored. The tag-based proximity detection and camera pedestrian detection pages compare costs and limits.
