User’s Manual
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.
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.
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.
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.
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.
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.
