Dahua 2-wire apartment video intercom system

Hangzhou, China

As modern society rapidly develops, residents are looking for more advanced features in their intercom systems. However, old apartment buildings often do not have data network wiring in place to install IP based intercom system. The cost associated with rewiring has become a barrier in many intercom system upgrade projects. Now, Dahua has a solution to this dilemma with the launch of its latest 2-wire apartment video intercom system, providing a cost effective, fast, simple, and convenient way to upgrade analogue intercom systems.

The Dahua 2-wire apartment intercom system is comprised of a VTNS1006A-2 switch, a VTH5222CH indoor unit, and an outdoor station VTO2000A-X for small apartments and VTO1210C-X for large apartments to seamlessly integrate and managed with the software, Smart PSS, to easily operate and manage the entire system.

The intercom system features simple wiring, as the VTNS1006A-2 switch and the VTH5222CH indoor unit use a two-wire interface. The switch is connected to the indoor unit using any two wires, which are used for signal transmission and power. There is no polarity and the switch has a network interface to connect with external networks and communicate with regular IP devices. The maximum supported distance between the switch and the device is 100 metres, while the maximum supported distance between switches is 30 metres.

The system also retains Dahua's regular IP apartment system functions and satisfies the requirements of most large apartments. With the VTO1210C-X large apartment outdoor station, each unit can support a maximum of 20 outdoor stations and 1000 indoor monitors. Each switch can support a maximum of six indoor monitors and only two series connections are needed between switches. The maximum number of switch connections is 30 and can satisfy the requirements for high rise apartments.

Each household can install a maximum of five VTH5222CH indoor monitors which can be used for group calls, and calls can be answered anywhere within the household, from where, users may also communicate with each other through the indoor monitors.

Indoor monitors can monitor IPC in real-time. To connect with a wired alarm and detection devices, the system will be implemented with a 24-hour protection by using the Smart PSS management system.  The Smart PSS software can be downloaded - it is convenient and able to facilitate smart management of entire areas, plus it can be flush-mounted or surface mounted to suit different installation requirements.

The system supports a maximum of 25 households, 10,000 IC cards, and 3000 fingerprints. Modules are simply connected in series, which is easy and convenient.

For small apartment applications, the VTO2000A-X IP outdoor station series uses a modular design. The front panels and the VTO2000A-C camera module can be used in combination with different modules to form a system of 2, 3, or 9 modules to suit different needs.  The installation box can be either flush-mounted or surface mounted to suit different installation requirements.

In addition, many residents want to have the 'mobility' option to talk to the visitor while no one is at home. The 2-wire apartment system can offer a mobile function to meet this requirement: accepting a visitor's call through the intercom system and remotely unlocking the door after ID confirmation. The Dahua 2-wire apartment intercom system can also initiate real-time surveillance, capture screen shots, record video, receive alarm information remotely, and monitor the house in real-time to give users peace of mind whilst away from home.
