V8.0.2

There might be risk if you update the program. Make sure that you back up the data before update to

avoid failure and data corruption.

Update Instructions1.2

Refer to the following .xlsx file for the situations before and after update.

Update Note.xlsx

Update Methods1.3

Non-applicable versions cannot be directly upgraded to V8.000.0000002.0. You need to upgrade

to the applicable versions first (see "1.1 Applicable Version"), and then to V8.000.0000002.0. If

you upgrade to V8.000.0000002.0 directly, the system prompts an update failure. The data will

not be replaced, and the original version remains after the service restarts.

You cannot update when hot standby is configured. Remove the hot standby before updating

to V8.000.0000002.0.

After update, you need to reconfigure distributed deployment.

After update, the program cannot be downgraded to earlier versions.

Downgrade or update among different programs is not supported. For example, you cannot

update DSS7016D/DR-S2 to DSS4004-S2, or update DSS4004-S2 to DSS7016D/DR-S2.

Cybersecurity RecommendationsAppendix 1

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

Update Guide

between 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.

Update Guide

Enable IP/MAC address filtering function to limit the range of hosts allowed to access the

device.
