VLAN Configuration
Virtual Local Area Network (VLAN) is frequently and widely applied. It is the basic to divide the network.
VLAN is the network that multiple devices are logically organized as one network, regardless of the
physical location of the devices. Every VLAN is a logical network with all functions and attributes of
traditional physical network. Every VLAN is a broadcast domain, and the broadcast packet can only be
forwarded within one VLAN. The broadcast packet cannot be forwarded across different VLANs.
VLAN Based on Port
VLAN based on port is that one switch can divide the logical working groups by controlling
interoperability between two and several ports. Dividing the port VLAN reasonably can enhance
network security, improve bandwidth availability, and reduce the probability of broadcast storm. This
series of products support 4094 VLANs. When you create the VLAN, you need to select a VLAN ID which
ranges from 2 through 4094. By default, VLAN 1 is created, and it cannot be deleted.
Application Example
Networking Requirement
There are two users, user 1 and user 2. They need to be in different VLANs because the network
function and environment they use are different. User 1 belongs to VLAN 2, connected to the switch

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 from Dahua 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

User’s Manual
Quick Operation 18
1024–65535, 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 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.

User’s Manual
Quick Operation 19
Enable IP/MAC address filtering function to limit the range of hosts allowed to access the
device.
