Overview 

Dahua VTH devices are indoor monitors that 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. The VTH series is used as part of a video intercom solution with compatible outdoor 
stations. 
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.
