2 Network Diagram
The network diagram below displays all the networking scenarios. Different models of the devices have different requirements. 1. For H series VTH and F series VTO.
When there are 6 devices (VTH+VTO) connected together, only a maximum of 2 devices can provide power output. 2. For G series VTH and S series VTO. When there are no more than 4 VTHs, the maximum current output of all the 12 VDC power is
500 mA. When there are more than 4 VTHs, the maximum current output of all the 12 VDC power is
300 mA. The power supply of HDCVI camera cannot be grounded. The product appearance is for reference only.

Cable Insertion Loss

Insertion loss refers to the situation of sending a signal from one end of the cable and receiving the signal at the other end of the cable. The calculation of cable insertion loss is as follows: Insertion Loss = 20 × Log (signal received/signal sent)

The cable insertion loss followed is collected from the laboratory environment, and is for reference only. The actual data might differ from that collected in the test environment.

4 Installation and Wiring
This chapter introduces the wiring of the device. The alarm input port is connected with dry contact. Do not install devices in environments that have condensation, high temperatures, dust
corrosive substances and direct sunlight. If the device behaves abnormally after you turn it on, cut off the power supply at once and
unplug the network cable. Power on again after you finish resolving the issue. Installation should be done by professional teams. Do not disassemble or repair the device by
yourself to avoid damaging the device. Contact after-sales service if you need any help. The recommended installation height of the device is 1.6 m from the ground.

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 1-4,094. 1. Find the mapping relationship between the DIP switch number and the address number you
plan to configure from the table. It follows a calculation rule that combines only the numbers listed in the Address No. to form a new address number. 2. Manually move the actuators corresponding to the DIP switches to the ON status, 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 relationship (DIP 3 equals to the address number of 4) in the table, and then manually move the actuator of DIP 3 to the ON status. 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 DIP 1 and DIP 2 combined together in the mapping relationship), and manually move both the actuator of DIP 1 and DIP 2 to the ON status. 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 1 combined together in the mapping relationship), and then manually move the actuator of DIP 8, DIP 3 and DIP 1 to the ON status.

Here is the list of commonly used VTH addresses (1-20) and their corresponding DIP switch number combinations.

Appendix 1 Cybersecurity Recommendations
Mandatory actions to be taken for basic equipment network security: 1. Use Strong Passwords
Please refer to the following suggestions to set passwords: The length should not be less than 8 characters. Include at least two types of characters; character types include upper and lower case letters,
numbers and symbols. Do not contain the account name or the account name in reverse order. Do not use continuous characters, such as 123, abc, etc. Do not use overlapped characters, such as 111, aaa, etc. 2. Update Firmware and Client Software in Time According to the standard procedure in Tech-industry, we recommend to keep your
equipment (such as NVR, DVR, IP camera, etc.) firmware up-to-date to ensure the system is equipped with the latest security patches and fixes. When the equipment is connected to the public network, it is recommended to enable the ”auto-check for updates” function to obtain timely information of firmware updates released by the manufacturer. We suggest that you download and use the latest version of client software. “Nice to have” recommendations to improve your equipment network security: 1. Physical Protection We suggest that you perform physical protection to equipment, especially storage devices. For example, place the equipment in a special computer room and cabinet, and implement well-done access control permission and key management to prevent unauthorized personnel from carrying out physical contacts such as damaging hardware, unauthorized connection of removable equipment (such as USB flash disk, serial port), etc. 2. Change Passwords Regularly We suggest that you change passwords regularly to reduce the risk of being guessed or cracked. 3. Set and Update Passwords Reset Information Timely The device supports password reset function. Please set up related information for password reset in time, including the end user’s mailbox and password protection questions. If the information changes, please modify it in time. When setting password protection questions, it is suggested not to use those that can be easily guessed. 4. Enable Account Lock The account lock feature is enabled by default, and we recommend you to keep it on to guarantee the account security. If an attacker attempts to log in with the wrong password several times, the corresponding account and the source IP address will be locked. 5. Change Default HTTP and Other Service Ports We suggest you to change default HTTP and other service ports into any set of numbers between 1024­65535, reducing the risk of outsiders being able to guess which ports you are using. 6. Enable HTTPS We suggest you to enable HTTPS, so that you visit Web service through a secure communication channel. 7. MAC Address Binding We recommend you to bind the IP and MAC address of the gateway to the equipment, thus
68

reducing the risk of ARP spoofing. 8. Assign Accounts and Privileges Reasonably
According to business and management requirements, reasonably add users and assign a minimum set of permissions to them. 9. Disable Unnecessary Services and Choose Secure Modes If not needed, it is recommended to turn off some services such as SNMP, SMTP, UPnP, etc., to reduce risks. If necessary, it is highly recommended that you use safe modes, including but not limited to the following services: SNMP: Choose SNMP v3, and set up strong encryption passwords and authentication
passwords. SMTP: Choose TLS to access mailbox server. FTP: Choose SFTP, and set up strong passwords. AP hotspot: Choose WPA2-PSK encryption mode, and set up strong passwords. 10. Audio and Video Encrypted Transmission If your audio and video data contents are very important or sensitive, we recommend that you use encrypted transmission function, to reduce the risk of audio and video data being stolen during transmission. Reminder: encrypted transmission will cause some loss in transmission efficiency. 11. Secure Auditing Check online users: we suggest that you check online users regularly to see if the device is
logged in without authorization. Check equipment log: By viewing the logs, you can know the IP addresses that were used to
log in to your devices and their key operations. 12. Network Log
Due to the limited storage capacity of the equipment, the stored log is limited. If you need to save the log for a long time, it is recommended that you enable the network log function to ensure that the critical logs are synchronized to the network log server for tracing. 13. Construct a Safe Network Environment In order to better ensure the safety of equipment and reduce potential cyber risks, we recommend: Disable the port mapping function of the router to avoid direct access to the intranet devices
from external network. The network should be partitioned and isolated according to the actual network needs. If
there are no communication requirements between two sub networks, it is suggested to use VLAN, network GAP and other technologies to partition the network, so as to achieve the network isolation effect. Establish the 802.1x access authentication system to reduce the risk of unauthorized access to private networks. Enable IP/MAC address filtering function to limit the range of hosts allowed to access the device.
