THE CHALLENGE

Government office visitors are granted access for a specific purpose and are permitted only within designated zones relevant to their visit. Once past the entry register, there was no mechanism to verify that visitors remained within their permitted area. A visitor registered at entry could move freely across the office - including into restricted zones - with no detection or alert in place.
Manual registers captured who entered the building but nothing beyond that. Security personnel could not monitor visitor movement across all zones simultaneously, leaving significant gaps in access control that created security and compliance risk across the facility.
  • No tracking after entry

    Manual register captured entry only - visitor movement across zones was completely unmonitored.

  • Unauthorised zone access undetected

    Visitors could enter restricted or unpermitted areas without triggering any alert.

  • Security coverage gaps

    Guards could not monitor all zones simultaneously - movement between areas went unobserved.

  • No evidence trail for incidents

    No timestamped record of where a visitor was at any point during their visit.

THE SOLUTION

We deployed a face recognition system across the government office that tracks visitor movement from entry through all internal zones. Each visitor is enrolled at entry with their permitted zone assigned. As they move through the facility, the system continuously matches their face against the enrolled database and verifies their zone against their permitted access. If a visitor enters a zone outside their permitted area, an instant alert is sent to the security team.
Flow: Visitor enrolled at entry with permitted zone -> Face recognition active across all zone cameras -> Movement tracked in real time -> Zone checked against permitted access -> Alert sent to security if unauthorised zone entered -> Full movement log on dashboard

WHAT CHANGED AFTER

Visitor movement tracked beyond entry for the first time - Zone-by-zone visibility from arrival to departure.

Unauthorised zone entry detected in real time - Security alerted instantly on any permitted zone breach.

Manual register replaced with automated face recognition - No reliance on self-reported visitor information at entry.

Complete audit trail for every visitor - Full timestamped movement record available for security review and compliance reporting.
