1 Overview
Dahua VTO Intercom devices allow tenants to view and talk with visitors and remotely unlock
doors all from an intuitive mobile app and an interior color indoor monitor. Each outdoor station
includes a 1.3 MP wide angle camera with manual rear pivot, two-way talk and enables remote
functions such as snapshot when ringing and the ability to record video and audio messages
to a VTH series monitor.
SIP Compatibility
Dahua Intercom devices are compatible with the Session Initiation Protocol version 2.0 (SIP),
a signaling protocol for Internet conferencing, telephony, presence, event notification, and
instant messaging. SIP is widely used to initiate and terminate Voice Over Internet Protocol
(VOIP) calls, as well as connect physical devices to mobile applications. Dahua Intercom
devices are ideal for single-family homes as well as large residential complexes or commercial
properties.
