Intercom System
A visitor presses the buzzer at the gate, but security is patrolling elsewhere and doesn't hear it — the visitor has to wait or call a staff member's personal phone just to get in.
TNT deploys an IP intercom system at the main gate, building lobby, and key access control points — allowing visitors to call and speak directly with reception/security on duty (via mobile app or a central screen), and release the door remotely on confirmation, no matter where the on-duty staff member is within the premises.
Architecture features
Two-way audio/video calling between visitors and reception/security on duty
Remote door release directly from the mobile app or central screen
Runs over IP network, not restricted to on-duty staff being at a fixed location
Integration with the access control system to log door-opening history
Supports multiple call points: main gate, lobby, parking, emergency exits
