Introduction The 2-wire analog indoor station (VTH) uses a 7-inch touch screen and uses the 2-wire system for communication. It supports preview of VTO and HDCVI cameras; supports intercom between VTO and VTH; and also remote unlocking, as well as connection to DMSS App. 1.2 Function Analog Communication Supports 2-wire communication. Video/Voice Call Make video or voice call to other VTOs. Monitoring Monitor VTO and HDCVI cameras. Auto Snapshot Take snapshots when calling or monitoring, and store them in the SD card. DND (Do Not Disturb) Mute call notifications. Remote Unlock Unlock doors remotely. Arm and Disarm Arm and disarm 6 alarm devices. Playback Play back videos and pictures in the SD card. Record View call and alarm records. 1 Message View messages, including videos, pictures. Wi-Fi Networking Connect to Wi-Fi networks. 2 2 Network Diagram See the network diagram below to see all the networking scenarios. When there are 6 devices (VTH+VTO) connected together, only a maximum of 2 devices can be connected to power output port. The power supply of HDCVI camera cannot be grounded. The maximum power output allowed is 12 VDC/200 mA. Wiring One VTO and One VTH The two wires connected to the positive and negative terminals of OUT cannot be short-

circuited. Line termination terminal and branch terminal are optional in this scenario. Figure 2-1 Network diagram Wiring One VTO and Two VTH (cascade connection) 3 Figure 2-2 Network diagram Wiring One VTO and Two VTH (parallel connection) 4 Figure 2-3 Network diagram Wiring Two VTO and Four VTH The DIP number of each VTO cannot be the same. Otherwise, connection might fail. 5 Figure 2-4 Network diagram Wiring Distance Between VTH and VTO It is recommended that the distance between the line termination terminal and the 2-wire controller not exceed 3 m. 6 Figure 2-5 Max distance 7 Table 2-1 Wiring Distance RVV Cable AWG Max.

DIP switches allow users to quickly preconfigure the VTH a variety of settings or operating modes. RS-485 and power output port Used to connect to other devices; and connect to the power supply. Analog two-wire port Alarm port Used connect to the alarm input and output devices. Include 6 alarm input ports, 1 alarm output port and 2 camera ports. 10 Figure 3-3 Alarm port Figure 3-4 RS-485 and power output port 11 4 Installation and Wiring The alarm input port is connected as dry contact. Do not install devices in harsh environment with condensation, high temperature, dust, corrosive substance and direct sunlight. In case of abnormality after powering on the device, cut off the power supply at once, and unplug the network cable. Power on after troubleshooting. Installation should be done by professional teams. Do not dismantle or repair the device by yourself in case of device failure. Contact after-sales service if you need any help. The recommended installation height of the device is 1.6 m from the ground. Figure 4-1 Port description 12 5 DIP Configuration Configure the DIP switches to achieve the function you would like to program. At the rear panel of the VTH, there are two sets of DIP switches, each of which has a 8-switch. 5.1 DIP Switch Basic Mapping Rule Table 5-1 DIP Switch mapping relations and function DIP Switch No. Corresp onding Address No. Function DIP 1 DIP 2 DIP 3 DIP 4 DIP 5 DIP 6 DIP 7 DIP 8 DIP 9 DIP 10 1 2 4 8 16 32 64 128 256 512 Used to program the address of the VTH. You can set a maximum of 4094 VTH address by using the 12 DIP switches. 13 DIP Switch No. DIP 11 DIP 12 DIP 13 DIP 13 DIP 14 DIP 15 DIP 16 DIP 16 Function Corresp onding Address No. 1024 2048 ON: Connect to HDCVI camera through unshielded twisted pair (UTP). OFF: Connect to HDCVI camera through coax cable. Reserved. ON: Set the VTH as the extension. OFF: Set the VTH as the main VTH. 5.2 DIP Switch Coding Rules This section introduces how to configure the address of a VTH through the coding rules of DIP switches. By setting the switches in combination, you can get any value from 1-4094. 1. Find the mapping relation between the DIP switch number and the address number you plan to configure from the table. It follows a calculation rule that combing only the numbers listed in the Address No. only to form a new address number. 2. Manually move the actuator(s) corresponding to the DIP switch(s) to the status ON, so that the address of the VTH can be configured. For example, if you want to set your VTH address as 4, you need to first find the mapping relation (DIP 3 equals to the address number of 4) in the table, and the manually move the actuator of the DIP 3 to the status ON. If you want to set your VTH address as 3, you need to do the calculation (1+2=3; which equals to the value of DIP1 and DIP 2 combined together in the mapping relation), and manually move both the actuator of DIP 1 and DIP 2 14 to the status ON. If you want to set your VTH address as 133, you need to do a more complex calculation (128+4+1=133, which equals to the value of DIP 8, DIP 3 and DIP 1combined together in the mapping relation), and then manually move the actuator of DIP 8, DIP 3 and DIP 1 all to status of ON. Here is the list of commonly used VTH addresses (1-20) and their corresponding DIP switch number combinations. Table 5-2 Common VTH Address (1-20) and DIP switch numbers VTH Address DIP Switch Combination Coding Rule 1 2 3 4 5 6 7 8 9 10 11 DIP 1 DIP 2 DIP 2+ DIP 1 DIP 3 DIP 3 + DIP 1 DIP 2 + DIP 3 DIP 3 + DIP 2 + DIP 1 DIP 4 DIP 4 + DIP 1 DIP 4 + DIP 2 DIP 4 + DIP 2+ DIP 1 15 VTH Address DIP Switch Combination Coding Rule 12 13 14 15 16 17 18 19 20 DIP 4 + DIP 3 DIP 4 + DIP 3+ DIP 1 DIP 4 + DIP 3+ DIP 2 DIP 4 + DIP 3 + DIP 2+DIP 1 DIP 5 DIP 5 + DIP 1 DIP 5 + DIP 2 DIP 5 + DIP 2+ DIP 1 DIP 5 + DIP 3 16 6 VTH Local Operation 6.1 Home Screen Figure 6-1 Home screen No. 1 2 3 4 5 6 7 Table 6-1 Home screen description Name Description Main VTH If there is no icon appeared, then it means this is an extension.
