This technical document is published for information purposes by Guangzhou Video-Tech Electronics.
In a policy of ongoing improvement, Guangzhou Video-Tech Electronics reserves the right to modify
the contents of this document and the features of the products referred to herein at any time and
without prior notice. Anysuch modifications shall be reflected in subsequent editions of this document.

Section1 - Introduction
System Features
• With only 2 wires (no polarity) throughout the whole installation, the 2-wire DT system is a simplified installation
system with minimum wiring and powerful features. The minimum wiring drastically reduces installation times and
errors. By means of FM video modulation and ASK data transmission technology, system provides better
protection against interference, which guarantees best color quality at all points of the installation.
• Centralized power supply for the entire system. With advanced power management, the whole system use only
one power supply, so there is no power supply needed for any Monitor or other system parts.
• Use Plug-in connectors and DIP switchers for more rapid installation.
• Flexible cable connection to wire, support in-out, branching and mixed mode.
• Multi Monitors for one apartment/house in same User Code, and automatically switching the video.
• Online searching and diagnose function for installer.
• Using PC to program and diagnose the system.
System Capacity
• Max. 4 Door Stations, or 3 Door Station plus 2 CCTV cameras, or 1 Door Station plus 6 CCTV cameras.
• Max. 32 Monitors in a system, max.4 Monitors in same User Code.
• Proximity access control function, max. 1000 user ID cards.
• Maximum 150 meters distance from Door Station to the farthest Monitor.
System Extension
• Connect Door Strike and Exit Button to Door Station directly.
• Connect door bell and extra ringer to Monitor directly.
• Control staircase light or relay executors for second electronic lock.
• Connect up to 6 CCTV cameras by DCU unit.
System Function
• Name list intercom
• Inner call intercom among Monitors in same Room Code
• One Monitor can be programmed as Guard unit
• Color Memo or SD card DVR function

Villa Application
Although the DT system is mainly designed
for the small apartment system usage, it can
be used in villa or villa group applications.
Multi Monitors can be installed in a family with
the same User Code, or many houses can
be connected as one system, and all of these
Monitors can have calling conversation each
other.

Apartment Applications
This is the most common way that the system
is used. One building or multi buildings can be
connected as one system. Every apartment
can open the door, and the users in the
system can have intercom talk each other.

Use the power of the system to supply for the electronic lock, so that the lock can connect to the Door Station directly,
without an additional power supply for the electronic lock. Note that the Door Station can only output a 12Vdc power;
therefore the kind of lock used is limited.

The rated power of the lock must be less than 12Vdc 300mA when using direct lock connection method.
The GND must connect to the negative of the lock, and the COM connects to the positive.
Jumper set to 1-2 position for Power-to-Unlock safety type; set to 2-3 position for Power-off-to -Unlock type(in
this case the Unlock Relay mode should be set to Normally Closed on DT CONFIG software)
The 5th bit of the DIP switches is for the unlocking time setting, its set to off by default, for 1 second unlocking
time. If set this bit to on, the unlocking time is 5 seconds.
If different unlocking time is needed to be configured, the DT CONFIG software can be used to change the

Proximity ID Card Operation
• Up to 1000 user cards can be registered by the Door Station.
• Easy management with LED state and Sound hint.
• There are two master cards, one MASTER CARD ADDcard and
one MASTER CARD DELETE card, When adding a new master
card, the old one will be replaced automatically.
• Card reading distance is from 3 to 5 cm.
The Master cards are necessary when you add or delete user cards,
Please keep the Master cards carefully. However, it is much easier to
manage the ID cards using DT-CONFIG software.

There are three kinds of intercom function available in the DT system.
1. Guard Unit Call
A Monitor can be assigned to be the guard unit Monitor, by setting on the OSD screen of the
Monitor. When the user's Monitor is in standby, press call button or intercom button, the intercom
page will show up on the screen, than select and confirm 'Call Guard Unit' item, and the Monitor
will call the guard unit Monitor, when the guard unit Monitor answers the call, conversation with
the guard person is started.
2. Inner Call
When multi Monitors are installed in one apartment, inner call is available. Note that all Monitors should have the
same User Code, and the Master and Slave address should be set on the Monitor(see page 40 for detail
information).
When the Monitor is in standby, press call button or intercom button, the intercom page will show up on the screen,
than select and confirm 'Inner Call' item, and other Monitors will ring at the same time. When any Monitor answers the
call, other Monitors will stop ringing and go back to standby state.
3. Intercom Call (Namelist)
The namelist intercom is for apartment to apartment calling. The user in one apartment can call other apartments by
selecting the name on the screen. In this way, it's no need to remember the ID(User Code or room address) of the
other users. A complete name list of all the users in the system can be upload to the Door Station by the DT CONFIG
software, and then the Door Station will send the name list to all Monitors.

User Code Setup
In the DT system, every apartment must have a unique identification called User Code. The DIP switches are used to
configure the User Code for each Monitor.
• Bit-1 to Bit-5 are used to User Code setting. The value is from 1 to 32, which have 32 different codes for 32
apartments.
• When multi Monitors are installed in one apartment, these Monitors have to use the same User Code setting,
and the Master/Slave mode should be set on the Monitor.
• Bit-6 is line terminal switch, which have to be set to ON if the Monitor is in the end of the line(bus), otherwise set
to OFF. The end of the line is terminal that no other section will start from it.
