discover the device.
4.3 VLAN Configuration
VLAN (Virtual Local Area Network) is frequently used during actual application; it is divided into
multiple network basics internally. VLAN is to organize several devices into one network
logically, regardless of the physical location of the devices. Each VLAN is a logical network,
which is equipped with all functions and attributes of traditional physical network. Each VLAN is
a broadcast domain; broadcast packet can only be forwarded within one VLAN, not across the
VLAN.
VLAN Based on Port
VLAN based on port means that one switch can realize the division of logical working groups
via controlling interoperability of between two and among several ports. Dividing port VLAN
reasonably can greatly improve network security and bandwidth use ratio, besides it reduces
the probability of broadcast storm. The model supports 4094 VLAN; it needs to select a VLAN

11
ID when creating VLAN, ranging from 2 to 4094. The switch creates VLAN1 by default and
VLAN1 cannot be deleted.
Application Example
Networking Requirement
There are two users, user 1 and user 2. These two users need to be in different VLAN due to
different network function and environment. User 1 belongs to VLAN2, connecting to switch
port G1/1 (Gigabit Ethernet 1/1); user 2 belongs to VLAN 3, connecting to switch port G1/2
(Gigabit Ethernet 1/2).
Figure 4-2 VLAN networking
Configuration Steps
The switch configuration is shown as follows.
1. Log in to the device. Refer to "4.1 First Login by Console Port".
2. Run the following command to create VLAN.
SWITCH #configure terminal
SWITCH (config)#vlan 2
SWITCH (config-vlan)# exit
SWITCH (config)#vlan 3
SWITCH (config-vlan)# exit
3. Run the following command to distribute ports into the VLAN.
SWITCH (config)# interface GigabitEthernet 1/1
SWITCH (config-if)# switchport access vlan 2
SWITCH (config-if)# exit
SWITCH (config)# interface GigabitEthernet 1/2
SWITCH (config-if)# switchport access vlan 3
SWITCH (config-if)# exit

Appendix 1 Cybersecurity Recommendations
Cybersecurity is more than just a buzzword: it’s something that pertains to every device that is
connected to the internet. IP video surveillance is not immune to cyber risks, but taking basic
steps toward protecting and strengthening networks and networked appliances will make them
less susceptible to attacks. Below are some tips and recommendations on how to create a
more secured security system.
Mandatory actions to be taken for basic device 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
device (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 device 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 device network security:
1. Physical Protection
We suggest that you perform physical protection to device, especially storage devices. For
example, place the device 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 device (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 1024~65535, reducing the risk of outsiders being able to guess which ports you
are using.

13
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 device, thus
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 device 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 device, 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 device 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.
