1 Overview
The Dahua Intercom Modular System is a complete intercom solution that offers full customization of
the entire system. This intercom system starts with a 2 MP outdoor video intercom module that offers
a wide-angle view lens, high-resolution images even in dark environments, and two-way talk. Then,
add optional modules that offer door access capability (card reader, fingerprint reader, and keypad),
call buttons, information text display, and status light indicators. The system also offers optional
accessories to flush-or surface-mount a two-or three-module intercom system.
