The Dahua DHI-VTO3211D-P4 4-Button Villa Outdoor Station is part of Dahua's VTH Series. VTH series products are digital video intercom home stations that integrate monitoring, two-way communication, and door management.
The VTH devices use an IP network, SNMP (Simple Network Management Protocol) technology, and network encryption technology to achieve a stable system, robust functionality, convenient operation, and safer data transmission.
These devices allow tenants to view and talk with visitors, record call sessions, monitor the surroundings from outdoor stations and IP cameras and remotely unlock doors. Visitors can also leave messages, which can be retrieved from the indoor monitor.
