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.
